A Data-Driven Approach to Stormwater Quality Analysis in Two Urban Catchments

The StormTac Web model, representing a low-complexity conceptual model (LCCM), was applied to two urban catchments featuring stormwater quality controls, a stormwater pond or a biofilter. The model calculates annual average runoff from annual precipitation and land-use specific volumetric runoff coefficients and baseflows (in storm sewers), which are multiplied by the corresponding mean stormwater quality constituent concentrations obtained from the recently upgraded StormTac Database, to yield constituent loads. The resulting runoff loads pass through the stormwater quality control facilities (a stormwater pond or a biofilter) where treatment takes place and its efficacy is described by “reduction efficiencies”. For the four selected stormwater quality constituents (TP, Cu, Zn, TSS) and two study catchments, a 201-ha residential Ladbrodammen and an 8.2-ha Sundsvall traffic corridor, the compositions of stormwater entering and leaving the control facilities were calculated by StormTac Web and compared against the measured data. In general, the calculated concentrations were smaller than the measured ones, and these differences were reduced, but not eliminated in all cases, by considering uncertainties in both calculated and measured data. Uncertainties in calculated values consisted of two components, a flow component (assumed as 20%) and a concentration component, which was assumed equal to the relative standard error (RSE) of the data in the StormTac Database. Explanations of differences in calculated and measured stormwater data were discussed with respect to temporal changes and trends in environmental practices and stormwater quality monitoring and enhancement by treatment.

Economic feasibility of in-motion wireless power transfer in a high-density traffic corridor

Electricity is expected to become a dominant power source in the transportation sector, but under a stationary recharging model, electric powered vehicles still suffer some disadvantages relative to conventional vehicles. Recent developments in wireless power transfer (WPT) technology can enable an alternative vehicle recharging model wherein power is supplied to vehicles while they are moving, mitigating the need for charging stops and high-capacity on-board energy storage. One of the greatest concerns associated with dynamic WPT is that the required infrastructure costs would be prohibitively high; however, the life-cycle costs and benefits of such a system have been under-researched. In this work, we apply a systems-level assessment to a case study of a WPT charging system located on the densely trafficked I-710 corridor in Los Angeles, California. Detailed cost estimates for electronics and implementation, high-fidelity energy consumption modeling, and survey-derived adoption projections are applied to evaluate scenarios of economic feasibility and environmental impact. Results show that a “1st-of-a-kind” system can achieve a payback in 20 years while maintaining operating cost advantages relative to petroleum fueling. System economics are shown to improve substantially with “nth-of-a-kind” capital costs. Discussion focuses on the effect of uptake trajectory on economic viability and detailed economics outcomes for light duty and heavy duty vehicles. • WPT roadway usage by both LDVs and HDVs improves system economics. • High utilization enables economical 1st-of-a-kind system. • Mature system achieves 20-year payback and driver cost savings (LDV: 58%; HDV: 37%). • Drastic emissions reductions provide non-monetized societal benefit.

A Grade Identification Method of Critical Node in Urban Road Network Based on Multi-Attribute Evaluation Correction

Accurately identifying the key nodes of the road network and focusing on its management and control is an important means to improve the robustness and invulnerability of the road network. In this paper, a classification and identification method of key nodes in urban road networks based on multi-attribute evaluation and modification was proposed. Firstly, the emergency function guarantee grade of road network nodes was divided by comprehensively considering the importance of road network nodes, the consequences of failure, and the degree of difficulty of recovery. The evaluation indexes were selected according to the local attributes, global attributes, and functional attributes of the road network topology. The spatial distribution patterns of the evaluation indexes of the nodes were analyzed. The dynamic classification method was used to cluster the attributes of the road network nodes, and the TOPSIS method was used to comprehensively evaluate the importance ranking of the road network nodes. Attribute clustering of road network nodes by dynamic classification method (DT) and the TOPSIS method was used to comprehensively evaluate the ranking of the importance of road network nodes. Then, combined with the modification of the comprehensive evaluation and ranking of the importance of the road network nodes, the emergency function support classification results of the road network nodes were obtained. Finally, the method was applied to the road network within the second Ring Road of Beijing. It was compared with the clustering method of self-organizing competitive neural networks. The results show that this method can identify the key nodes of the road network more accurately. The first-grade key nodes are all located at the more important intersections on expressways and trunk roads. The spatial distribution pattern shows a “center-edge” pattern, and the important traffic corridors of the road network show a “five vertical and five horizontal” pattern.

The assessment of the soil mineralization processes along the traffic corridors from urban and rural areas in Romania

The soils of the green areas located near the traffic corridors accumulate different pollutants, especially heavy metals, which have an important impact on the microbial decomposition processes. The extracellular enzymes can be used as an indicator of the metabolic activity of the microorganism communities. Four extracellular enzymes - α and β glucosidase, alkaline phosphatase and alanine aminopeptidase - were assessed in green areas close to the traffic zones in several urban, peri-urban and rural localities in Romania. The data showed that the highest values of enzymatic activities were registered in rural areas. At the same time, the spatial dynamics of the studied enzymes revealed an important variability between the three types of sampled areas, without a clear pattern of their distribution.

From the Vicus to the House of the Painter : Archaeological research in Aquincum Civil Town in the past 20 years (2000–2020)

Unlike the legionary camp and the Military Town, the area of Aquincum Civil Town was not built up after the Roman Period, and, therefore, it is available for research with the exception of two traffic corridors that have existed for hundreds of years and the residential area and a factory (Gasworks) on the outskirts of the present-day city. Therefore, our understanding of the settlement has continuously evolved for 130 years now and knowledge continued to accumulate in the past 20 years. Moreover, modern development projects, authenticating excavations, and the review of archaeological assemblages that had been brought to light earlier yielded a wealth of new information, which in some cases fundamentally changed our perception of the Civil Town’s topography and chronology.

Quantifying Land Use/Land Cover Change and Urban Expansion in Dongguan, China, From 1987 to 2020

Dongguan has experienced the most rapid urbanization since the Chinese reform and opening policy. To analyze the urban expansion in this city, in this study, 12 land use/land cover maps were produced using a multiple classifiers system on the Google Earth Engine platform. A long time-series land use dataset from 1987 to 2020, was achieved. The results indicate that, during the past 33 years, the urban area increased by 13.84 times and reached 1483.06 km <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> in 2020, whereas cultivated land and forest continually decreased because of rapid urbanization. By analyzing the changes in urban forms and landscape indexes, Dongguan experienced a diffusion–coalescence–diffusion phase, and its urban expansion can be divided into three stages: The early-age urbanization stage (1987–1996), the rapid urbanization stage (1996–2011), and the intensive urbanization stage (2011–2020). The development of the economic and dual-level administration of Dongguan expanded the urban area surrounding the towns and traffic corridors, and, finally, formed a connected urban area. The urban expansion, just like sparking spots firing the prairie, is special and conforms to a Dongguan urbanization pattern.

Geopolitički i bezbednosni aspekti kosovsko-metohijskog čvora

Due to the intertwined and parallel interests of the great powers in Kosovo and Metohija, a kind of geopolitical knot has been created, as a field of aggressive geopolitical actions by non-Balkan and Balkan neighbouring political factors, which is reflected in current events, making them politically and security complex. After 2008, we have witnessed the unilaterally recognized so-called independence of Kosovo, which continued the process of internal transition and territorial fragmentation of Serbia that is clearly marked as a challenge and threat even in the current geopolitical and security context. Therefore, the paper has tried to show and explain the importance of the southern Serbian province, first of all emphasizing its geographical and geopolitical importance as a central area on the Balkan Peninsula, which makes it very important for the control of traffic, economic, communication, strategic and other corridors. The second part of the paper presents a geopolitical analysis of the current events in the south of Serbia and the consequences for the country's internal political structure and international position. In addition, the security aspects of the Kosovo-Metohija knot have been analysed, with a focus on national security and security problems caused by the violent exclusion of the Serbian territory and the self-proclamation of the so-called independence of Kosovo, in order to find sustainable solutions for the security situation in the south of Serbia.

The City of Zagreb Lower Town Urban mobility development program

Common development issues in historic city centers are dense urban blocks (with buildings that do not follow modern construction standards), narrow traffic corridors, and low mobility of pedestrians and cyclists. Modern solutions, like smart traffic control systems, parking restrictions, the introduction of speed limitations and dynamic yellow lanes, increasing control of existing yellow lanes, and the establishment of multimodal solutions, are introduced to eliminate traffic problems in these areas. When it comes to the abovementioned development issues, the historic Lower Town area in Croatia’s capital Zagreb, with residential and commercial buildings and infrastructure dating from the beginning of the 20th century, is no exception. Following a very strong earthquake that hit in March 2020, severely damaging the structures in Zagreb’s historical center, a program for the complete reconstruction of this area is being developed, which will contain the Urban mobility development program. This paper presents the process and the results of Zagreb City’s Lower Town urban transport reprogramming performed by the University of Zagreb, Faculty of Civil Engineering. The main premise of the Zagreb historic center reconstruction program is that the quality of life in the area will be improved through the regeneration of neglected and unorganized city blocks, as well as the planning and construction of new public spaces. The aspiration is the transformation of Lower Town into the "15-minute city". The prerequisite for this is (1) improved mobility and (2) reshaped transportation system, with the emphasis on cost-effective technical solutions and the integration of zero-emission modes of transport, and green mobility. At the same time, it will be necessary to preserve buildings and infrastructure that are part of the identity of the City and to prevent the transformation of the reconstruction process into a process of gentrification.

Novel Policies are Required to Reduce Pediatric Lead Exposure from Legacy Lead (Pb) in Soil and Air

In 1925, a U.S. conference on lead (Pb) additives tacitly approved their use in petrol. Over five-decades an exponential increase of air lead occurred from commercial marketing of leaded petrol and the sale of automobiles. The ability to measure microgram quantities of Pb was unavailable to medical researchers until the late 1960s and early 1970s. The clinical application of advanced analytical technology demonstrated that pediatric lead exposure was excessive. Beginning in the mid-1970s, actions were taken to curtail Pb additive and decreases of pediatric lead poisoning coincided with decreased air Pb from leaded petrol use. Exogenous Pb exhaust particles are absorbed through inhalation and ingestion routes of exposure. Exogenous Pb is metabolically mistaken for calcium and stored endogenously in bones, teeth, and other tissues. Endogenous Pb has intergenerational effects. All organs, most notably the nervous system, are affected. Clinical studies indicate that there is no safe level of Pb exposure. A worldwide ban on leaded petrol was achieved on August 30, 2021. Banning leaded petrol corresponded with marked decreases in lead exposure. However, exogenous Pb dust persists in soil as a legacy from the era of leaded petrol. Soil Pb is remobilized into the air. Because of traffic congestion and Pb dust emissions, population centers are of particular concern. An exceedingly strong association exists between soil Pb and blood Pb indicating that at the community-scale Pb dust mitigation is necessary to decrease pediatric Pb exposure. Urban soil Pb and blood Pb studies indicate the risk of excessive exposure from legacy Pb dust in communities is highest where the median soil Pb is ≥ 50 mg/kg. The objective of this article is to demonstrate the practical application of an advanced hand-held analytical instrument to map Pb in children’s playgrounds adjacent to a major traffic corridor. We illustrate soil Pb mapping and then consider mitigation procedures for primary prevention of legacy Pb. Mapping soil Pb provides an informed basis for advising parents and encouraging community mitigation responses for reducing pediatric Pb exposure from legacy Pb dust. The soil health-plant health-animal/human health signaling nexus is compromised by legacy Pb. For the medical pediatric community, the existence of legacy lead requires new policies to address intervention of the soil-air-blood linkages of the Pb exposure pathway.

Size-Segregated Elemental Profile and Associated Heath Risk Assessment of Road Dust along Major Traffic Corridors in Kolkata Mega City

Particle size distribution (PSD) of road dust has significant repercussions on atmospheric pollution by road dust resuspension. The PSD of road dust at a few major commercial, traffic, and residential sites in Kolkata mega city was analyzed in the size range of &lt;28–2000 µm. Predominance of the coarse size range (212–600 µm followed by 106–212 µm) was observed. In size-segregated road dust, Fe (4.02–31.2 g kg−1) dominated other elements and was followed by Mg (2.13–10.9 g kg−1), Mn (79.2–601 mg kg−1), Li (395.8–506.8 mg kg−1), and others. Fine particles (&lt;28 μm) had higher elemental concentrations than coarser ones. Cd and Li showed the highest degree of enrichment compared to the Earth’s crust, but only Cd posed significant ecological risk due to its high ecological toxicity. Individual elements did not post significant non-cancer health risks, except for Li in children. However, the cumulative non-cancer risk from all toxic elements for children was almost four times higher than the acceptable level. Lifetime exposure to carcinogenic elements at the current level may pose 5 to 6 times higher cancer risk in the adult population than the acceptable risk of one in a million.

Mere Nuisance or Growing Threat? The Physical and Economic Impact of High Tide Flooding on US Road Networks

High tide flooding (HTF) already affects traffic in many US coastal areas, but the issue will worsen significantly in the future. While studies show that large storm surge events threaten to be ever more costly, less damaging, but more frequent HTF events remain understudied and potentially carry a comparable economic impact. This study advances our understanding of the risks and impacts of HTF on vulnerable traffic corridors using hourly tide gauge water levels, sea-level rise projections, and link-level spatial analysis. It is the first study to estimate HTF economic impacts for varying levels of intervention, including reasonably anticipated driver-initiated rerouting and ancillary protection of adjacent property. The 2020 annual national-level costs of $1.3 to $1.5 billion will increase to $28 to $37 billion in 2050 and $220 to $260 billion in 2100 for medium to high greenhouse gas (GHG) emissions scenarios, respectively. Total costs over the century are $1.0 to $1.3 trillion (discounted 3%). Additional cost-effective protection by building sea walls or raising road surfaces could significantly reduce 2100 costs to $61 to $78 billion, but there remain many barriers to adopting least-cost adaptation decisions, and these gains may only be realized with careful planning and information sharing.

Scheduling of Traffic Entities Under Reduced Traffic Flow by Means of Fuzzy Logic Control

This paper presents the design of a fuzzy logic-based traffic scheduling algorithm aimed at reducing traffic congestion for the case of partial obstruction of a bidirectional traffic lane. Such a problem is typically encountered in rail traffic and personal rapid transportation systems with predefined and fixed traffic corridors. The proposed proportional-derivative (PD) fuzzy control algorithm, serving as a traffic control automaton, alternately assigns adaptive green light periods to traffic coming from each direction. The proposed fuzzy logic-based traffic controller has been compared with the conventional traffic control automaton featuring fixed-durations of green light intervals. The comparison has been carried out within a simulation environment for four different probability distributions of stochastic traffic flows at each end of the considered traffic corridor. Results have shown that the proposed fuzzy logic-based traffic controller performance is far superior to that of the conventional traffic control law in terms of achieving shorter vehicle queue lengths and less disparity in queue lengths for all considered simulation scenarios.

Locating ship strike risk hotspots for fin whale (Balaenoptera physalus) and sperm whale (Physeter macrocephalus) along main shipping lanes in the North-Western Mediterranean Sea

The Pelagos Sanctuary is the only pelagic marine protected area in the Mediterranean Sea, instituted for the conservation of cetaceans. Considering the number and size of commercial and touristic ports located along its coasts, this protected area is highly impacted by human activities, and especially marine traffic. Fin whales and sperm whales are regularly sighted in the Pelagos Sanctuary, and ship strikes with large vessels are one of the main threats affecting these two species. Mapping hotspots of distribution along main shipping lanes could be an effective conservation tool, as they directly allow locating high risk areas. In this work, we used data collected during summer from 2009 to 2019, along main marine traffic corridors in the central region of Pelagos Sanctuary. Ship strike hotspots have been identified, considering the persistence of distribution hotspots over the 11 years period. Hotspots occurrence has then been predicted over the entire Pelagos Sanctuary area applying Generalized Additive Models, allowing for ship strike risk assessment over the marine protected area. Our results highlighted the recurrence of important areas for both species along shipping lanes characterized by high vessel traffic, identifying regions where to address conservation measures.

The characteristics of spatial expansion and driving forces of land urbanization in counties in central China: A case study of Feixi county in Hefei city.

Urbanization in Central and Western China has attracted increasing attention in the advent of new-type urbanization in China and the age of 'Global Urbanism'. Although land urbanization is at the epicenter of Chinese urbanization, its process and driving forces in counties beyond the Eastern coastal areas are less known. This paper therefore seeks to investigate the spatial expansion and driving forces of land urbanization in Feixi county, a relatively advanced county neighboring Hefei city proper in Anhui province in Central China. Based on the land-use change survey data, remote sensing interpretation data, and statistical yearbook data of Feixi county from 2002 to 2016, it is revealed that the overall scale of urban land in Feixi county increased remarkably, though with obvious temporal and geographical variants. The year 2009 appears to be the cutting line between quantity-based land urbanization and quality-based land urbanization. Land urbanization rate is sensitive to both geographical distance and traffic accessibility to Hefei city proper. Driving forces of land urbanization in Feixi county are summarized as: (1) central city expansion, (2) government-led industrial park construction, and (3) large industrial projects along traffic corridors. A better understanding of urbanization in Feixi county cannot be fulfilled without taking into account the wider spatial process in Hefei city and the Yangtze River Delta city-region.

Monitoring and Assessing the Environmental Noise along a Busy Traffic Corridor of Ahmedabad City, India

Noise pollution is a growing problem across the world and one which many people may not be aware of the impacts on their health. The environmental noise, and in particular the road traffic noise, remains a major environmental problem affecting the health and well-being of millions of people. With this background, a comprehensive ‘noise pollution assessment study’ was undertaken for a busy traffic corridor of Ahmedabad city of India. The traffic corridor which spans around 22.25 km passes through a mix of different areas like educational, commercials and residential. A two week long field survey was carried out on this corridor during 10-23 May, 2018 at 24 locations spread over the entire corridor. The assessment reveals that the average noise level always exceeded the prescribed guidelines of World Health Organization (WHO) for the daytime noise (75 dB (A) for Industrial area, 65 dB (A) for Commercial area, 55 dB (A) for Residential area and 50 dB (A) for Silence zones), which is quite alarming. For a major portion of the traffic corridor (79.6%), even the minimum noise level was above the permissible average noise level which is a matter of great concern. The highest noise level observed was 86.0 dB (A). Clubbing the ranks of the traffic corridor segments for the noise indicators like LAeq, Lmin, Lmax, L90, L50, L10 and LNP revealed that locations like Akhbarnagar followed by Naranpura were in the nosiest. Looking to implications of the high noise levels on the human health and productivity, it is important to initiate suitable mitigation measures. The present comprehensive study brings forth the spatial and quantitative aspects of noise pollution across the busy corridor of the city which would be of great help to the civic administration in understanding the magnitude of the problem and subsequently initiate suitable mitigative measures.

Comparison of conventional high speed railway, maglev and hyperloop transportation systems

Increasing the speed of transportation has been a subject that human beings have been working on for many years. Because of insufficient traffic corridors, the interest of more passenger in limited time and the advancement of railway technology, the high-speed ground transportation systems have developed. Nowadays, these time-saving transportation systems are becoming important increasingly and systems that will ensure these are implemented and new ones are being researched. High speed ground transportation systems can be divided into three categories: Conventional high-speed railway, Maglev and Hyperloop transportation system. Within the scope of this study, it is aimed to investigate the advantages and disadvantages aspects of high speed transportation systems by comparing in terms of speed, capacity, energy consumption, cost and environmental effects. Conventional high-speed railways can provide high capacity, comfort and safety and reliability thanks to enormous operational experience as regards other systems. The Maglev technology can offer more remarkable travel times, energy efficient and better operational performance. However, high investment cost and incompatibility with other modes are seen the disadvantage features of this technology. The Hyperloop technology is a considerable innovative transportation system which is popularized with publishing design document by Elon Musk in 2013. Projected high-speed and appealing travel times can be evaluated as the advantages of the Hyperloop transportation system. However, there are safety, reliability, comfort and engineering design challenges to overcome in this technology. Taking everything into consideration, the Hyperloop transportation system has potential to be an alternative mode to other systems.

Impact of COVID-19-Related Traffic Slowdown on Urban Heat Characteristics

Governments around the world have implemented measures to slow down the spread of COVID-19, resulting in a substantial decrease in the usage of motorized transportation. The ensuing decrease in the emission of traffic-related heat and pollutants is expected to impact the environment through various pathways, especially near urban areas, where there is a higher concentration of traffic. In this study, we perform high-resolution urban climate simulations to assess the direct impact of the decrease in traffic-related heat emissions due to COVID-19 on urban temperature characteristics. One simulation spans the January–May 2020 period; two additional simulations spanning the April 2019–May 2020 period, with normal and reduced traffic, are used to assess the impacts throughout the year. These simulations are performed for the city of Montreal, the second largest urban centre in Canada. The mechanisms and main findings of this study are likely to be applicable to most large urban centres around the globe. The results show that an 80% reduction in traffic results in a decrease of up to 1 °C in the near-surface temperature for regions with heavy traffic. The magnitude of the temperature decrease varies substantially with the diurnal traffic cycle and also from day to day, being greatest when the near-surface wind speeds are low and there is a temperature inversion in the surface layer. This reduction in near-surface temperature is reflected by an up to 20% reduction in hot hours (when temperature exceeds 30 °C) during the warm season, thus reducing heat stress for vulnerable populations. No substantial changes occur outside of traffic corridors, indicating that potential reductions in traffic would need to be supplemented by additional measures to reduce urban temperatures and associated heat stress, especially in a warming climate, to ensure human health and well-being.

Life cycle environmental impact of a high-speed rail system in the Houston-Dallas I-45 corridor

The Houston-Dallas (I-45) corridor is the busiest route among 18 traffic corridors in Texas, USA. The expected population growth and the surge in passenger mobility may result in a significant impact on the regional environment. This study uses a life cycle framework to predict and evaluate the net changes of environmental impact associated with the potential development of a high-speed rail (HSR) System along the I-45 corridor through its life cycle. The environmental impact is estimated in terms of CO2 and greenhouse gas (GHG) emissions per vehicle/passenger-kilometers traveled (V/PKT) using life cycle assessment. The analyses are performed referring to the Ecoinvent 3.4 inventory database through the phases: material extraction and processing, infrastructure construction, vehicle manufacturing, system operation, and end of life. The environmental benefit is evaluated by comparing the potential development of the HSR system with those of the existing transportation systems. The vehicle component, especially operation and maintenance of vehicles, is the primary contributor to the total global warming potential with about 93% of the life cycle GHG emissions. For the infrastructure component, 56.76% of GHG emissions result from the material extraction and processing phase (23.75 kgCO2eq/VKT). Various life cycle emissions of HSR except PM are significantly lower than for passenger cars.

Defining priority areas for blue whale conservation and investigating overlap with vessel traffic in Chilean Patagonia, using a fast-fitting movement model

Defining priority areas and risk evaluation is of utmost relevance for endangered species` conservation. For the blue whale (Balaenoptera musculus), we aim to assess environmental habitat selection drivers, priority areas for conservation and overlap with vessel traffic off northern Chilean Patagonia (NCP). For this, we implemented a single-step continuous-time correlated-random-walk model which accommodates observational error and movement parameters variation in relation to oceanographic variables. Spatially explicit predictions of whales’ behavioral responses were combined with density predictions from previous species distribution models (SDM) and vessel tracking data to estimate the relative probability of vessels encountering whales and identifying areas where interaction is likely to occur. These estimations were conducted independently for the aquaculture, transport, artisanal fishery, and industrial fishery fleets operating in NCP. Blue whale movement patterns strongly agreed with SDM results, reinforcing our knowledge regarding oceanographic habitat selection drivers. By combining movement and density modeling approaches we provide a stronger support for purported priority areas for blue whale conservation and how they overlap with the main vessel traffic corridor in the NCP. The aquaculture fleet was one order of magnitude larger than any other fleet, indicating it could play a decisive role in modulating potential negative vessel-whale interactions within NCP.

Inter-urban travel forms one of the main spatial and economic features of any nation&rsquo;s economic landscape. Understanding and forecasting inter-urban movement is a crucial input for urban and regional transportation planning. This study therefore was carried out to develop trip generation model of selected cities in Niger State. Questionnaire survey was carried in three main urban centres in the state namely; Minna, Bida and Suleja. Four (400) copies of questionnaires were administered at the three major public motor parks where travelers usually board vehicles for inter-city travels Niger state.&nbsp; Using multiple stepwise regression model analysis, six independent variables namely; travel distance (TD), travel time (TT), population (PP), public institution (PI) and fare charged (FC) were regressed against the dependent variable (Y) which is inter urban travel flow (ITF). However, only 2 independent variables; that is population (PP) and fare charged (FC) were good and significant for explaining the variation in the flow of inter urban trips in the state. Two variables record R2 of 1.00 which implies 100% contribution to explanation of the variation in the inter-urban travel in Niger State. The study also discovered that Minna-Suleja route constitutes the heaviest traffic corridors in the state. In view of these findings, it was recommended that adequate public transport provision should be made to meet inter urban travel needs within the state by NSTA and a more comprehensive regional transportation planning for the entire state is recommended to cover other important towns that could not be covered in this study. &nbsp; Key words: Inter urban, travel, pattern, flow, generation, attraction.
