To analyze various factors influencing the accident severity of urban river-crossing tunnels, 12 influence factors were selected according to the three traffic elements of vehicle, road, and environment, including accident-involved vehicle type, tunnel length, tunnel speed limit, accident occurrence time, and weather. These factors were based on the historical data of 14 urban river-crossing tunnels in Shanghai. A binary logistic regression model was also utilized to identify significant influence factors and analyze the influence degrees of their accident severity. Significance analysis reveals that accident occurrence place, accident-involved vehicle type, tunnel speed limit, number of vehicles involved, and accident type are …
Exploring Factors Contributing To Lane Changes During Left Turns On Quadruple Left-Turn Lanes At Signalized Intersections, Fulu Wei, Zhenyu Wang, Jian Lu

Quadruple left-turn lanes are employed gradually at some major intersections in Jilin, China. At these intersections, frequent lane changes during left turns of vehicles can lead to vastly disordered traffic operations. In this study, the factors contributing to lane changes during left turn behaviors at quadruple left-turn lane intersections were interpreted based on a field survey. In total, data on 192 green intervals and 550 individual lane-change behaviors were collected in Changchun, Jilin Province. A lane-changing rate model was established to predict the rate of lane changes during left turns. In addition, an interval selection model was built to estimate …

Public transit is an essential part of a city’s transportation. An efficient transit system makes a city more sustainable by reducing the number of single occupancy vehicles leading to a reduction in emissions, energy consumption and less congestion on streets. Public serviceability is an important indicator to indicate how good a transit route is determined; however, it could change during the years since population density is variable. This study is intended to do a comparison between serviceability of a bus line in Memphis, Tennessee for one zip code area to point out the necessity of considering route revising in short-term …

Florida experienced serious pedestrian safety problems and had the highest pedestrian fatality rate in the U.S. from 2008–2011. Pedestrian safety at signalized intersections is the most serious concern due to frequent and severe conflicts between vehicles and pedestrians. Pedestrian features directly related to pedestrian safety are used to increase driver compliance behaviors and reduce vehicle-pedestrian conflicts. This project aimed to explore driver behaviors at signalized intersections with four identified pedestrian features—“STOP HERE ON RED,” “NO TURN ON RED,” “TURNING VEHICLES YIELD TO PEDESTRIANS,” and “RIGHT ON RED ARROW AFTER STOP” signs—by using an innovative safety data source, the Strategic Highway …

Petaling Jaya is a Malaysian city in the Petaling district of Selangor, over the past few years it has witnessed a dramatic growth in terms of population size and geographical importance. This has led to constant congestions throughout the city. A significant reduction in the annual cost of road accidents, congestion, energy consumption and pollution in the city can be obtained by implementing a modal shift from private vehicles to public transport. Urban transportation problems are highlighted in this study as well the factors that influence the use of private and public transportation. A survey was carried out on users …

The rising trend of motorization and improving socio-economic status of Thai people directly influences the aggravating road safety situation with fatalities and permanently disabled injuries of about 130,000 and 500,000 respectively over the past decades. An estimated annual cost from road crashes amounts to about US$2,500 million, 3.4 percent of Gross National Product (GNP), undoubtedly inflicts Thailand with a burning public health concern in the South East Asian region. This paper addresses an in-depth study through crash investigation and reconstruction which has not yet been practised in Thailand to identify the contributory factors in road crashes by the concerned authorities. …
