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.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation research focuses on modeling traffic conditions affected by disruptive events such as work zones, incidents, and hurricanes. Using a combination of field data and simulation experiments, this research tried to address the relationship between disruptive events and their impact on traffic conditions and driver behavior. The first half of the dissertation assesses the impact of work zones. First, a data-driven assessment of the traffic impact of work zones using different data sources was conducted. A tool was developed for practitioners to estimate the delay and travel times of planned work zones. Second, traffic flow and speed prediction models were developed for work zones in order to assist with the better scheduling of work activity. Machine learning approaches were used to develop the prediction models. In addition to work zone effects, the effects of another special event, baseball gameday conditions, were also studied and traffic prediction models were developed. Third, using naturalistic driving study data, classification algorithms categorized work zone events into crashes, nearcrashes, and baseline conditions. In the second half of the dissertation, the focus shifts to the effect of emergency on evacuation. Two chapters in this section present the results of different traffic management strategies -- 1) contraflow crossover and ramp closure optimization and 2) reservation-based intersection control in connected and autonomous vehicle environment.

Transyogi Road is the main road used by transportation originating from the Depok city, Bogor district, Bekasi city and Bekasi district. The Transyogi Road and the networks connected to it have experienced a significant increase in traffic density each year, this fact is based on the indicator level of the VC ratio on the Transyogi and surrounding road segments which have reached 0.8 at busy times. With the increase in trips generated from Bekasi Regency and an increase in residential density in Depok and Bogor, it has the potential to increase generation and the traffic attraction from and to the area is affecting by the construction of the Cimanggis - Cibitung toll road. This Traffic Impact Analysis aims to predict the impact of the construction of the Cimanggis - Cibitung Toll Road on the Jatikarya exit, and determine the form of improvement needed, harmonize the decisions regarding land use with traffic conditions, the number and location of access, and alternative improvements . This study method uses 4 (four) transportation modeling, analysis of road capacity, vehicle speed .. From the results of this study, it was concluded that before the toll road the Transyogi road had a performance with a V / C ratio of 0.8 and an average speed of 20 km / hour (if do nothing), while after the exit of the jatikarya toll was operated the V / C ratio was 0.7 and the average speed is 23 km / h (do nothing). While the performance of Transyogi road in the design year 2025 without performing geometric improvements (do nothing) has a road performance with a V / C ratio of 0.98 and an average speed of 12-13 km / hr.

The Impact

Industrialization can benefit individuals, communities or states as it opens new opportunities for economic, social and human development. The stream of globalization is impelling Bangladesh to adopt the technologies of the Fourth Industrial Revolution. Bangladesh has pursued export-oriented industrialization, with its key export sectors include textiles, shipbuilding, fish and seafood, jute and leather goods etc. Communication system plays a very important role in accelerating the place of industrialization of a country. Along with the industrialization, communication system of Bangladesh has also been greatly improved. Various major projects have already been implemented and many more new projects have been under taken. Even then various unplanned developments are creating traffic congestion on our highways which become a big problem for us. Factories are being setup on both side along the highways in an unplanned manner to accelerate the pace of industrialization. As a result, roadways cause a slew of issues, including reduced capacity, increased travel time delays, queue length, increased fuel consumption, and roadway accidents, all of which result in unrecorded economic losses. So, it is vital to investigate and measure the traffic impact of industrial installations along highways in order to achieve long-term sustainability. Traffic Impact Assessment (TIA) is a technical examination of traffic problems and safety concerns associated with a particular development. In this study, we have assessed the traffic impact due to setting up a new industry along the Dhaka-Aricha Highway(N-5). It is mainly focused on the impact of the new generated traffic will have on the Dhaka -Aricha highway’s traffic system after the installation of an industry.  Furthermore, the findings may be used to take the anticipatory role in the future for becoming a beneficiary to set up a sustainable industry along the highways.

<p>Este trabalho descreve o uso de um simulador na analise do impacto de veículos pesados na capacidade e no nível de serviço de interseções rodoviárias não semaforizadas. O impacto na capacidade é medido através da determinação de fatores de equivalência veicular, enquanto que a avaliação do nível de serviço da interseção baseia-se nos tempos médios de espera dos veículos durante as manobras de cruzamento. Os resultados obtidos mostram que os veículos que causam maior impacto na operação das interseções são os caminhões articulados, devido ao seu comprimento, e os caminhões médios, devido a sua menor relação potência/peso. Os fatores de equivalência obtidos são, em geral, maiores que equivalentes veiculares adotados pelo HCM de 1994, mostrando a necessidade de se desenvolver um método para analise de interseções não semaforizadas mais adequado as condições nacionais.</p><p>ABSTRACT</p><p>This paper describes the use of a simulator to analyze heavy vehicle impacts on capacity and level of service of rural unsignalized intersections. The impact on capacity is measured d by the do termination of equivalence factors and the level of service a assessment is based on average delay crossing times. The results indicate that the two vehicle classes responsible for the greatest intact are articulated trucks (due to their length) and medium-sized trucks, because of their poor power-to-weight ratio. The equivalence factors obtained are greater than those shown in the 1994 HCM, demonstrating the need for development of an unsignalized intersection analysis method more adequate to the Brazilian operational and vehicle conditions.</p>

This paper describes the techniques used in the planning and design of a system of passing lanes for the Trans-Canada Highway in Yoho National Park. The techniques, which include a traffic simulation model, were developed to allow the evaluation of the impact of low-cost operational improvements such as passing lanes on the level of service. The traffic simulation model allowed the investigation of a wide range of highway alternatives in addition to changes in traffic flow, traffic stream characteristics, and vehicle performance characteristics. The passing lane designs described in the paper are based on the concept of incorporating passing lanes within the existing highway cross section. The design concept has evolved from the experimental passing lane project in Banff. In addition to geometric design, signing, and road marking guidelines, warrants for bicycle lanes on the Trans-Canada Highway are also presented. Key words: highway planning and engineering, two-lane highways, traffic simulation model, level of service, passing lanes, Trans-Canada Highway.

AbstractEvery year, numerous environmental disasters and emergencies occur across the globe with far-reaching impacts on human health and the environment. The ability to rapidly assess an environmental emergency to mitigate potential risks and impacts is paramount. However, collating the necessary evidence in the early stages of an emergency to conduct a robust risk assessment is a major challenge. This article presents a methodology developed to help assess the risks and impacts during the early stages of such incidents, primarily to support the European Union Civil Protection Mechanism but also the wider global community in the response to environmental emergencies. An online rapid risk and impact assessment tool has also been developed to promote enhanced collaboration between experts who are working remotely, considering the impact of a disaster on the environment and public health in the short, medium, and long terms. The methodology developed can support the appropriate selection of experts and assets to be deployed to affected regions to ensure that potential public health and environmental risks and impacts are mitigated whenever possible. This methodology will aid defensible decision making, communication, planning, and risk management, and presents a harmonized understanding of the associated impacts of an environmental emergency.

Effective formation and implementation of forest policy can only be achieved with orientation to the most important goal—increasing society’s welfare. The global problem is, at present, that the impact of forests on society welfare indexes have not been identified. The aim of the study is to design an assessment model and assess the impact of Lithuanian forests on the society welfare index. The impact of forests was determined by multiplying the country’s welfare of society index by the forest contribution coefficient. In this study, to assess the index of the welfare of Lithuanian society, a five-dimensional model with 16 indicators was applied. The study is based on the Eurostat database and on Lithuanian forestry statistics. The Lithuanian welfare of society index calculated according to the model was 51.4% and the contribution of forests in this index was 3.9%. It represented 7.6% of the index of the welfare of society. Forests have the greatest impact in the environmental dimension, according to the assessment results.

Proper Operation

Transport networks are essential for societies. Their proper operation has to be preserved to face any perturbation or disruption. It is therefore of paramount importance that the modeling and quantification of the resilience of such networks are addressed to ensure an acceptable level of service even in the presence of disruptions. The paper aims at characterizing network resilience through weighted degree centrality. To do so, a real dataset issued from probe vehicle data is used to weight the graph by the traffic load. In particular, a set of disrupted situations retrieved from the study dataset is analyzed to quantify the impact on network operations. Results demonstrate the ability of the proposed metrics to capture traffic dynamics as well as their utility for quantifying the resilience of the network. The proposed methodology combines different metrics from the complex networks theory (i.e., heterogeneity, density, and symmetry) computed on temporal and weighted graphs. Time-varying traffic conditions and disruptions are analyzed by providing relevant insights on the network states via three-dimensional maps.

Abstract Health Impact Assessment (HIA) and Social Return on Investment (SROI) are beneficial public health methodologies that assess potential effects on health including social, economic and environmental factors and have synergies in their approaches. This paper explores how HIA and SROI can complement each other to capture and account for the impact and social value of an assessed intervention or policy. A scoping review of academic and grey literature was undertaken to identify case studies published between January 1996 and April 2019 where HIA and SROI methods have been used to complement each other. Semi-structured interviews were carried out with nine international experts from a range of regulatory/legislative contexts to gain a better understanding of past experiences and expertise of both HIA and SROI. A thematic analysis was undertaken on the data collected. The review identified two published reports which outline when HIA and SROI have both been used to assess the same intervention. Interview results suggest that both methods have strengths as standalone processes i.e. HIAs are well-structured in their approach, assessing health in its broadest context and SROI can add value by monetizing social value as well as capturing social/environmental impact. Similarities of the two methods were identified i.e. a strong emphasis on stakeholder engagement and common shared principles. When questioned how the two methods could complement each other in practice, the results indicate the benefits of using HIA to explore initial impact, and as a platform on which to build SROI to monetarize social value. HIA and SROI methodologies have cross-over. The research suggests potential benefits when used in tandem or combining the methods to assess impact and account for health and social value. Innovative work is now being carried out in Wales to understand the implications of this in practice and to understand how the results of the two methods could be used by decision-makers. Key messages HIA and SROI methods can be used in tandem to capture both the health impact and social value of policies and proposed interventions. HIA and SROI when used together can provide valuable information to inform decision makers around the health impact and social value of proposed policies and interventions.
