Traffic Impact Assesment Practice in Indonesia

Construction of a new traffic should consider its effect on the road network around the construction. Effect on the road network seen by the size of the building will be planned. Assessment is done by looking at whether the development affects the access roads around the building (site impact), affecting access roads and intersections in one direction around (traffic impact), or to affect the road network in the city that need consideration to change the city development master plan (master plan).Analysis of the impact of traffic in Indonesia has become a liability since the issuance of Law No. 22 Year 2009 regarding Traffic and Road Transportation but in practice they face many obstacles because the Act is not equipped with its implementing regulations. The existence of these guidelines it is important to harmonize the implementation of the traffic impact analysis in the area (provincial/ district / city).Benefits of Traffic Impact Analysis is quite large but is still faced with some fairly complicated problems when applied in developing countries. Limapornwanitch (2020) has studied the Implementation of Traffic Impact Assessment in Southeast Asian Cities: Case Studies of Thailang and The Philippines and stated that the implementation of the analysis of the impact of traffic in Southeast Asia are faced with major problems that trouble the institution (institutional), no / not available procedures / standards, lack of knowledge and lack of budget. These four problems if left unchecked can accumulate into a bigger problem is the uncontrolled land use. Limapornwanitch (2020). For the condition of Indonesia, the biggest problems facing today is the lack of determination of a standard model to be applied in the analysis of traffic impacts.

Estimating vehicle miles traveled (VMT) in urban areas using regression kriging

SummaryThe recent increase in demand for performance‐driven and outcome‐based transportation planning makes accurate and reliable performance measures essential. Vehicle miles traveled (VMT), the total miles traveled by all vehicles on roadways, has been utilized widely as a proxy for traffic impact assessment, vehicle emissions, gasoline consumption, and crashes. Accordingly, a number of studies estimate VMT using diverse data sources. This study estimates VMT in the urban area of Bucheon, South Korea, by predicting the annual average daily traffic for unmeasured locations using spatial interpolation techniques (i.e., regression kriging and linear regression). The predictive performance of this method is compared with that of the existing Highway Performance Monitoring System (HPMS) method. The results show that regression kriging could provide more accurate VMT estimates than the HPMS method and linear regression, especially with a small sample size.

BOOSTING CATEGORISATION SYSTEM IN THE UK TRICS DATABASE AND DEVELOPING NEW TRIP PRODUCTION MODELS

In the UK, TRICS is a national trip generation databases and system. It is recommended to be used in quantifying traffic impacts of new residential developments. Thus, any enhancement in its methodology will positively influence the transport assessment process. This paper has three objectives; first, to examine the possibility of proposing new statistically-proven grouping for the TRICS residential land use subcategories. The second objective is to use the proposed grouping to construct parsimonious models for home-based trip production that can aid in quantifying traffic impact assessment. The third objective is to examine the validity of the developed models against two of the most internationally recognised trip information systems; the UK TRICS and the US ITE Trip Generation Manual. The statistical analysis ended up with new more accurate grouping where based on it eight trip production model were built. The developed models were found to be practical and rigorous.

Road traffic noise impact assessment in a breeding colony of cinereous vultures (Aegypius monachus) in Spain.

There is a global and growing concern with regard to anthropogenic noise impact on wildlife and natural habitats, but it is difficult to find consensus regarding scoping and assessment tools. This study adapts noise mapping procedures, common to most European countries, to a low traffic road (below 1000 vehicles per day) noise impact assessment in a breeding colony of the largest bird of prey in Europe. Results show that nest sites are located avoiding road traffic Leq levels higher than 40 dB. This means a road-effect zone of up to 500 m width from road margins, which previous scientific literature only refers in cases of traffic volumes higher than 10,000 vehicles per day. This finding is a noticeable impact by road traffic noise that reduces the breeding potential habitat more than 11% within the study area. This work shows the feasibility of expanding common methods and mapping tools for assessing and managing environmental noise in protected areas, which has worthwhile implications for both acoustics and conservation.

Traffic Impact Assessment: A Case of Proposed Hypermarket in Skudai Town of Malaysia

This paper deals with traffic impact assessment (TIA) of a proposed commercial development in the neighbourhoods of Skudai Town in the Johor Bahru region. We used three regimes: Trip Rate Analysis, Cross-Classification Analysis, and Regression Analysis to assess the future traffic expected to be caused by a development – a proposed Tesco hypermarket (TH) in Skudai. The obtained mean trip rates were critically examined for forecasting traffic. The results indicated no significant variances from the estimated mean entry trip rates as mentioned in the Trip Generation Manual, Highway Planning Unit (HPU) of Malaysia. The estimated mean trip rates were used to measure the performance of a critical intersection in the immediate vicinity the development. The critical Intersection was analyzed using SIDRA software to estimate the delay – a criterion for determining the level-of-service (LOS) provided to motorists. Traffic projections made for horizon year 2025 depicted a LOS ‘F’ with 2716.9s of average delay. Traffic improvements were also proposed to mitigate the impact of future development and traffic conditions. The study provided a framework for the estimation of trip rates for Malaysian conditions along with some guidelines for their adoption. These insights to TIA can assist developers or local authorities in decision making.

Assessing the Influence of Traffic Impact Assessments on Land Use Development and Decision Making

Russian agriculture is one of the industries operating in the unstable economic situation in a developing market taking into account risks of the world economy, economic, political, and climatic factors. The role of agriculture is to provide people’s needs for food, significant effects on employment, the efficiency of domestic production, and way of life in rural areas by obligatory preserving food security in Russia. One of the major tasks for agriculture is the development of innovations and investments aimed at improving the competitiveness of the domestic agricultural sector. Russia’s membership in the WTO since 2012 is getting a particular importance in the innovation and investment support of agriculture. The strategy of innovative development of the Russian Federation until 2020 “Innovative Russia—2020” assumes three possible options for innovative development: inertial (directed on imports), catch-up development and a local technological competitiveness and a variant of achieving leadership in leading scientific and technical sectors, and fundamental research. A positive point is that the strategy provides an algorithm of state support of the innovation cycle. The innovation cycle is the process associated with the sequence of innovation transformations (scientific or business ideas) in products, technology, business process and launches it on the market for commercial use. A positively developing regional aspect is of great importance.

Developing a Generic Methodology for Traffic Impact Assessment of a Mixed Land Use in Dhaka City

A proficient transportation system has a great importance on the infrastructural as well as the overall economic development of a country. But the traffic volume of Bangladesh especially of the capital city Dhaka is growing at an alarming rate with the large number of population and development projects. The result is ultimately an inefficient transport system with traffic jam, congestion, irregular parking, low level of service, injured road network etc. A traffic impact assessment or TIA is an evaluation of the potential effects that a particular development’s traffic will have on the transportation network in its impact area. TIA includes formulation of traffic management schemes and recommendation of infrastructure for possible transportation and traffic problems that will be encountered during the construction and operation phases of projects. This article primarily focuses on developing a framework of TIA methodology for a mixed land use in context of Bangladesh. This study will use the TIA process to evaluate the effects of an ongoing project on its adjacent roads’ transportation system. From the ultimate result it is seen that, before the project was completed, the level of service of the New Market-Science Laboratory section of Mirpur road was E at base year condition (2009), but after the completion of the project the level of service of the same road has been turned into F at 2013.

Traffic Impact Simulation for Road Construction Project

With the increasing traffic contradiction between supply and demand, urban traffic problems have become quite complex. Reasons for traffic congestion have become much more diverse. During the construction of urban road project, the surrounding road network will encounter a huge impact, traffic problems therefore emerged. Simulation is an important means for transport impact assessment, which has an important role for construction traffic impact analysis. Accordingly, traffic simulation is particularly important for policy setting and traffic organization. Taking an improvement project of Changjiang rapid road in Zhongshan city for example, this paper used the professional simulation software Vissim to analysis the impact of Qiwan road during the construction project. The simulation and traffic evaluation results can give some forward-looking and targeted measures about traffic safety, traffic organization, road facilities alteration and so on. The traffic impact analysis results shown that traffic safety and high-efficiency transport system must protected by good traffic re-organization projects and the simulation method is an effective mean to actualize traffic impact assessment.

The traffic impact assessment to the project of Nguyen Hue walking street

The government of Ho Chi Minh City has a plan to develop the current Nguyen Hue avenue to the walking street. In order to evaluate the feasibility of the project, it is necessary to conduct the traffic impact assessment. By using the simulation technique, several scenarios have been developed to identify the relevant solutions for the traffic improvement in this area. The traffic assessment is conducted via a process of OD demand analysis by using four-step model, which is improved from the previous model, HOUTRANS (2004) (The Study on the Urban Transport Master Plan and Feasibility Study in City Metropolitan Area). The proposed scenario, which can be considered as the most relevant solution for this project, is to convert some roads around Nguyen Hue avenue into one-way streets. Specifically, Ton That Thiep, Ngo Duc Ke street and Nguyen Hue avenue are changed into one-way streets in the direction of Pastuer and Dong Khoi street. Hai Trieu, Mac Thi Buoi, Huynhh Thuc Khang street are converted into one-way streets in the opposite direction.

An intersection turning movement estimation procedure based on path flow estimator

AbstractEstimation of intersection turning movements is one of the key inputs required for a variety of transportation analysis, including intersection geometric design, signal timing design, traffic impact assessment, and transportation planning. Conventional approaches that use manual techniques for estimation of turning movements are insensitive to congestion. The drawbacks of the manual techniques can be amended by integrating a network traffic model with a computation procedure capable of estimating turning movements from a set of link traffic counts and intersection turning movement counts. This study proposes using the path flow estimator, originally used to estimate path flows (hence origin–destination flows), to derive not only complete link flows, but also turning movements for the whole road network given some counts at selected roads and intersections. Two case studies using actual traffic counts are used to demonstrate the proposed intersection turning movement estimation procedure. Copyright © 2010 John Wiley & Sons, Ltd.

Regional traffic impacts of logistics-related land use

The outsourcing of logistics activities to logistics service providers leads to a demand for new logistics-related land development. At the moment (minimising) regional traffic generation is not a major decision criterion for site selection and development. For a sound traffic impact assessment, information on trip generation of logistics facilities like transfer depots, distribution centres and warehouses is necessary. Surveys conducted in the case study region Hamburg, Germany, provide such information. Applying the survey results, different logistics land use development scenarios are assessed in this paper. The results show that strategic location of logistics areas can reduce traffic and traffic impacts.

Engineering modeling of traffic noise in shielded areas in cities

A computational study of road traffic noise in cities is presented. Based on numerical boundary-element calculations of canyon-to-canyon propagation, an efficient engineering algorithm is developed to calculate the effect of multiple reflections in street canyons. The algorithm is supported by a room-acoustical analysis of the reverberant sound fields in the source and receiver canyons. Using the algorithm, a simple model for traffic noise in cities is developed. Noise maps and exposure distributions of the city of Amsterdam are calculated with the model, and for comparison also with an engineering model that is currently used for traffic noise impact assessments in cities. Considerable differences between the two model predictions are found for shielded buildings with day-evening-night levels of 40-60 dB at the facades. Further, an analysis is presented of level differences between the most and the least exposed facades of buildings. Large level differences are found for buildings directly exposed to traffic noise from nearby roads. It is shown that by a redistribution of traffic flow around these buildings, one can achieve low sound levels at quiet sides and a corresponding reduction in the percentage of highly annoyed inhabitants from typically 23% to 18%.

A Study on the Local Trip Generation Characteristics of Government Office Land Use

The trip generation characteristics of the eight government office complexes in Quezon City are examined through site characteristic survey. The preliminary estimates of person trips generated by this type of land use are obtained and assumed A.M. and P.M. peak hour factors needed for traffic impact assessments are established. Result analysis suggest that the estimated weekday trip rate in person trips is a reliable rate for Philippine use however, peak hour rates which are derived based on some assumptions need to be verified through detailed traffic survey. Initial step which entails site characteristic survey from the established ITE methodology are conducted. The trip generation rates for government office complex type of land use and suitable for local use are ascertained.

Low frequency noise impact of road traffic in the Netherlands

Current traffic noise impact assessments are usually based on broadband A‐weighted noise indicators. A more complete picture and better correlation with annoyance and health effects may result from indicators that include temporal aspects and frequency character. These aspects are currently under investigation at RIVM. This paper gives an evaluation of low frequency noise impact from road traffic in the Netherlands. The results are based on low frequency noise maps covering the entire road network. In particular the effectiveness of various types of noise control measures, such as noise barriers or walls, porous asphalt layers and reduction of noise emission, with regards to low frequency impact were studied. The results indicate for low frequency noise levels, powertrain noise and freight traffic in general, are of major importance for environmental quality.
