Revitalizing Urban Mobility:A Comprehensive Analysis of Traffic Flow and Sustainable Solutions at the Un-signalized Taxila Intersection

In recent years, traffic congestion has become one of many cities’ most significant financial and ecological concerns worldwide. It also costs citizens a substantial amount of time and fuel. Many experts believe that identifying traffic congestion characteristics is the first step in reducing traffic congestion. This study aimed to determine the extent of traffic congestion and fuel consumption at Taxila Chowk. The research’s primary methodological tools were a traffic volume survey and peak hour volume study using Aimsun software. According to this study, auto-rickshaws, bicycles, motorcycles, and trucks were the most common modes of transportation. Traffic flow is particularly heavy in the morning, noon, and evening hours. It was revealed that the H.M.C. road is the most congestion-prone route compared to the other four routes. Also, the distinctive design of rickshaws and bus stands and the misplacement of fruit and vegetable markets play a considerable role in Congestion. The level of service of the four routes is almost intolerable, and the sole P.O.F. road that offered comparable better services to city commuters is an acceptable illustration. The study has also identified the amount of fuel consumption on each route, focused on the environmental impact of Congestion due to emissions of green gasses, and provided feasible solutions in the form of alternatives.

Inbound traffic capture link-design problem independent of assumptions on users’ route choices

In some traffic management situations, a cordon (a set of points at which traffic flows into a given area) is set in a road network to establish a reference for the location of equipment to implement traffic measurements and controls (e.g., traffic volume surveys and congestion charging). However, few studies have focused on the optimum location of a cordon. We devise a problem denoted the inbound traffic capture link-design problem to select the optimum combination of links for inclusion in a cordon. We regard this combination as the minimum number of links that can capture traffic on all routes, under the condition that there is a path between nodes inside the cordon that is not captured. We formulate this model by employing the graph theory concept of the minimum cut, and use the concept of a Steiner tree with auxiliary network flows to express the constraint of ensuring that there is an uncaptured path inside a cordon. After a basic formulation, to obtain an identical cordon, we devise two subsidiary schemes. In addition, we perform a linear relaxation of our method to reduce its computational cost. The results of computational experiments confirm that our model selects the optimal cordon location formed by a combination of capturing links and also outputs an identical cordon as a boundary line of an area. As the model is computationally feasible, even when applied on a large network, we believe it will have a wide range of practical applications.

A study on source separation of traffic vehicle noise using deep learning

In order to reduce the environmental damage caused by road traffic noise, it is not only necessary to measure the amount of traffic by vehicle type and the resulting noise level but also convert them into big data for monitoring them. To achieve this, a monitoring system needs to be developed that can more accurately classify vehicle types and evaluate the noise level of each vehicle in motion. In recent years, the development of AI has significantly improved the performance of vehicle counting systems, and these systems are already being used in traffic volume surveys. However, a system that simultaneously measures traffic noise and converts it into data has yet to be developed, and the specification and prototyping of such a system is of utmost importance. This paper presents a Traffic Monitoring System, a novel system that automatically collects data on road traffic noise, which includes a noise source separation system to evaluate traffic noise, and strives to establish the related elemental technologies. Specifically, the Traffic Monitoring System uses cameras and microphones installed on edge devices to acquire road video and audio, and the system then performs vehicle detection, vehicle speed estimation, and noise evaluation for each vehicle.

Analysis and Evaluation of Methods Used in Measuring the Intensity of Bicycle Traffic

The work presents the methods of collecting and processing data with the use of devices used in individual measurement methods. Based on the collected video materials, the number of vehicles was determined, which at both measuring points actually exceeded each of the tested cross-sections of the bicycle path. More precise determination of the means of transport was divided into three categories: bicycles, electric scooters, and PT (personal transporters). The data collected with the use of each of the devices was properly processed and aggregated into a form that allows for their mutual comparison (they can be used to manage the energy of electric vehicles). Their greatest advantages and disadvantages were indicated, and external factors that had an impact on the size of the measurement error were identified. The cost of carrying out the traffic volume survey was also assessed, broken down into the measurement methods used. The purpose of this paper is to analyse and evaluate the methods used to measure bicycle traffic volume. Four different measurement methods were used to perform the practical part, which included such devices as a video recorder, microwave radar, perpendicular radar, and a meter connected to an induction loop embedded in the asphalt. The results made it possible to select a rational method for measuring the volume of bicycle traffic. The measurements carried out allow optimization of bicycle routes, especially for electric bicycles. The results indicate the method of physical counting of vehicles from video footage, thanks to which it is possible to achieve a level of measurement accuracy equal to 100%.

EVALUASI KINERJA LALU LINTAS SEBELUM DAN SESUDAH ADANYA FLYOVER GANEFO MRANGGEN (DEMAK)

The flyover construction is an effort to break down traffic jams in Indonesia. One of them is the construction of the Ganefo Mranggen (Demak) flyover. The work on the construction of this flyover has been initiated by the Bina Marga Office of Central Java Province since 2015. When this research took place in 2021, the flyover was still in the process of being completed. So the purpose of this paper is to know the degree of saturation when the flyover is functioning. In this study using research methods in the form of data collection. Because this research is an investigative activity to obtain facts from known symptoms, seek factual information, collect data for evaluation. In this study, secondary data from the Office of Highways 2019 was used. Data collection was obtained from literature studies and direct surveys. Secondary data is data obtained directly from the Related Office. This data is in the form of traffic volume survey data and road geometry. The result of this research is that after construction of the flyover the degree of saturation is reduced which was originally for the direction of Semarang - Purwodadi of 0.45 with a service level of C to 0.17 with a service level of A. As for the opposite direction or the direction of Purwodadi - Semarang, the degree the initial saturation was 0.81 with service level D to 0.33 with service level B. So it can be seen that the flyover construction has a significant impact on the service level of road performance.Keywords: flyover, degree saturation, point of conflict

Study of traffic volumes

"The area of transportation planning deals with transportation facilities (usually streets, roads, walkways, bike lanes, and public transit lines)." It is vital to assess the present state of traffic volume and anticipate the future state of traffic volume in this field traffic volume survey. The purpose of traffic volume studies is to determine the number, movement, and categories of highway vehicles in a given region. An attempt was made to grasp traffic patterns throughout various time periods using data collection. The characteristics of the traffic flow at that crossroads also have an impact on traffic control. As a consequence, the study's findings are valuable in controlling traffic at the intersection and giving some corrective measures to improve traffic safety in the region. Based on the findings, corrective actions such as road widening or enhanced public transit may be recommended.

Analisis dan Mitigasi Emisi Gas Buang Akibat Transportasi (Studi Kasus Kabupaten Magetan)

The Intergovernmental Panel Climate Change (IPCC) states that transportation contributes 13.1% of emissions (IPCC, 2006). Magetan Regency plans to support Indonesia in reducing emissions by 20% by 2040 by analysing and mitigating greenhouse gas (GHG) emissions generated by the transportation sector. The analysis was conducted by calculating greenhouse gas (GHG) emissions based on traffic volume survey data and calculating the fuel oil (BBM) used to obtain the amounts of emissions generated. From the analysis, it was found that CO2 emissions generated by the transportation sector in Magetan Regency amounted to 3,105,318.08 tons/year in 2020 and had the potential to increase by 3.31% per year. As mitigation actions, three activities are proposed, namely the use of public transportation, the movement of walking to school and greening. From the three actions, the total emissions are expected to be reduced by 1,422,516 tons/year or equivalent to 45% reduction of total emissions if the three proposed activities are implemented. If this is implemented, Magetan Regency will be able to contribute 0.22% of GHG emission reduction by 2040. If all districts in Indonesia also implement this mitigation, the transportation sector will contribute 9.15% of the emission reduction in Indonesia in 2040.

Brief design and numerical calculations for a secondary road

Based on the traffic volume survey, the standard traffic volume conversion is considered, and then the road traffic volume is predicted. Through the calculation, the maximum annual average daily traffic volume in the design life is obtained, and then the road grade and design speed of the design road are determined. The Annual Average Daily Traffic (AADT) is converted into Directional Design-Hour Volume (DDHV), and then the number of lanes of the road is determined. Collect the terrain data of the route area through the field survey, and then carry on the interior design. The route schemes are compared and the optimal route scheme is selected. AUTOCAD and a professional road design software were used to assist in the design of road line selection, horizontal curve design, vertical section design, cross section design and drainage design. Through the calculation, the design parameters such as the maximum synthetic slope, the average slope and the minimum length of superelevation transition section are obtained. Afterwards, the parameters in horizontal curve, vertical curve and superelevation-widening were checked manually.

Method for Obtaining Better Traffic Survey Data

Road traffic surveys determine the number and type of vehicles passing by a specific point over a certain period of time. The manual estimation of the number and type of vehicles from images captured by a camera is the most commonly used method. However, this method has the disadvantage of requiring high amounts of manpower and cost. Recently, methods of automating traffic volume surveys using sensors or deep learning have been widely attempted, but there is the disadvantage that a person must finally manually verify the data in order to ensure that they are reliable. In order to address these shortcomings, we propose a method for efficiently conducting road traffic volume surveys and obtaining highly reliable data. The proposed method detects vehicles on the road from CCTV (Closed-circuit television) images and classifies vehicle types using deep learning or a similar method. After that, it automatically informs the user of candidates with a high probability of error and provides a method for efficient verification. The performance of the proposed method was tested using a data set collected by an actual road traffic survey company. As a result, we proved that our method shows better accuracy than the previous method. The proposed method can reduce the labor and cost in road traffic volume surveys, and increase the reliability of the data due to more accurate results.

DESIGN OF A TRAFFIC SIGNALISATION SCHEME AT OLA-OLU INTERSECTION, ILORIN, NIGERIA

Ola-Olu intersection in Ilorin metropolis, Nigeria, is a 3-legged intersection in a typical urban centre of a developing economy. It is presently traffic warden controlled at morning peak period on weekdays and occasionally in the evening when there’s an event in a neighbouring public event centre that is expected to increase the traffic at the intersection. It is observed that the delay experienced at the intersection is quite high and traffic crashes at the intersection is a weekly occurrence. The study thereby aims at ameliorating the hazards by designing a fixed-time traffic signalization for the intersection. The objectives are to i. determine the geometric layout of the intersection ii. determine the traffic volume and vehicular turning movement pattern and iii. design and provide the signal timings at the T-intersection. Traffic volume survey and geometric layout survey were carried out at the intersection and analyzed to determine the optimum cycle length and signal setting using the Webster’s method. A 3-phase fixed time traffic signalization of 155 seconds cycle length was designed for an effective signal traffic control. The green time for phases 1, 2 and 3 are 102 seconds, 16 seconds and 22 seconds respectively. The implementation of the traffic signal will enhance both traffic flow and safety at the intersection.

Exploration on Pavement Surface Conditions Attributed To Mineral Freight and Logistics Operations on Kuantan Road Network

The most active mineral mining operations in Malaysia are located in Kuantan, Pahang. The rapid increases of the minerals operations are of concern due to its significant impacts on the environment and human health. While effects to the environment and human health are a great of concern, the effect to the transportation system also should not be neglected. With the continuous growth of these industries, there will be more heavy vehicles generated on road transporting minerals related products leading to several issues especially on road pavement damages. Pavement damages are always associated with its optimum function and may contribute to road crashes. There are several factors that influenced the pavement damages such as weather changes, quality of material use, improper maintenance and traffic operations. This study was conducted to explore the pavement damages occurrence based on traffic operation which focusing on heavy vehicles composition as centre for critical analysis. To achieve this study, the identification of regular routing used for minerals logistic operation from the mining source to the port was chosen as study location. This study was conducted by using visual observation survey and traffic volume survey. A set of historical data on route inspection supplied by Road Care also been used for analysis. Then, data obtained were analyzed using road disability level and road rating assessment. The result shows that the road rating leading to Kuantan Port was less satisfactory (rating C) with the marks of 7.27 and the highest type of damage found was cracking with 36% followed by rutting (33%) and potholes (31%). The outcomes from this study were hoped to bring some understanding on the impact of heavy vehicles towards transportation system within a local road network in Kuantan.

Performance of Exclusive Bus Lanes in Chennai

A bus lane is a lane which is provide only for operating buses and used to avoid traffic congestion. The current bus transit system in Chennai, known as MTC (METROPOLITAN TRANSPORT CORPORATION), is accommodating about 4 million transport units sufficient to accompany increasing number of passengers. Buses have to share the lane with other vehicles, which affects their capacity, speed, reliability, and quality of service. Due to traffic congestions, travel during peak hours in Metropolitan cities has become unattractive. An attempt has been made in this paper to provide lanes only for operation of buses. Three arterial roads connecting Kelambakkam to Sholinganallur, Chennai central to TambaramVandaloor zoo to Tambaram were selected for the study. Traffic volume survey was conducted in these areas. Based upon the survey conducted and analysis made, suggestions are proposed for the exclusive bus lanes for theselected area where traffic congestion is more during peak hours.
