A general summary of progress concerning the magnitude and extent of the total physical needs of Indiana's highways was pre­ sented at the 42nd Annual Road School. The report also included a preliminary estimate of the cost of eliminating the physical defi­ ciencies within 15 years. During the past year additional information concerning the needs study has been collected, analyzed, and evaluate...

We present a difference-in-differences analysis of the road safety effects introducing tolls on SCUT highways in Portugal, policy motivated purely by financial considerations, as congestion was never an issue. Using negative binomial count models and comprehensive dataset all mainland municipalities covering 2008 to 2014, we find that led increase total numbers accidents injuries where are loca...

Traffic congestion of streets and roads constitutes a critical problem which is aggravated by the rise in the number of vehicles and by greater urbanization. The slow pace in the development of new highways and roads and public opposition to the widening of existing streets in some locations has forced the city managers to optimally use the existing infrastructures in order to effectively manag...

Road traffic injury related deaths can be considered interplay of increasing speeds and rising traffic volume on our roads. Present study considers various circumstances and in depth analysis of fatal road accidents. This study on 100 fatal cases is an attempt to interpret various aspects of this so called rising pandemic of modern society. Out of 100, 88 % were male, 12 % female. Pedestrians a...

This work describes a color Vision-based System intended to perform stable autonomous driving on unmarked roads. Accordingly, this implies the development of an accurate road surface detection system that ensures vehicle stability. Although this topic has already been documented in the technical literature by different research groups, the vast majority of the already existing Intelligent Trans...

Mainland China accounted for about 7% of the global road fatalities in 2008. Road crashes happening on Chinese roads were deadly. On average, one person died in every four reported traffic crashes. Despite the scarcity of data, substantial rural-urban differences were found. In the rural areas, higher-order Highways, roads with no lighting and some heavy vehicles warrant particular attention fr...

In China, traffic accident data is published annually by the Traffic Management Research Institute of the Ministry of Public Security [1]. Accidents without casualties are usually not included. To gain a complete understanding and reliable insight of Shanghai traffic accidents, the project team collected the original accidents records on 192 Shanghai roads between 1-1-2009 and 12-31-2009. The o...

Accurate Annual Average Daily Traffic (AADT) information is important to many applications including roadway design, air quality compliance, travel model validation, etc. Yet complete or even extensive coverage of a network to collect traffic count data is impractical due to the cost involved. There have been studies to estimate AADT for interstate highways, expressways, urban roads, and rural ...
