Traffic accidents are one of the leading causes of fatalities in the US. An important indicator of survival rates after an accident is the time between the accident and when emergency medical personnel are dispatched to the scene. Eliminating the time between when an accident occurs and when first responders are dispatched to the scene decreases mortality rates by 6%. One approach to eliminatin...

Car ownership in China reached 194 million vehicles at the end of 2016. The traffic congestion index (TCI) exceeds 2.0 during rush hour in some cities. Inefficient processing for minor traffic accidents is considered to be one of the leading causes for road traffic jams. Meanwhile, the process after an accident is quite troublesome. The main reason is that it is almost always impossible to get ...

The rapid population growth and increasing economic activities have resulted in the tremendous growth of motor vehicles which is considered one of the primary factors responsible for increasing road accidents in many metropolitan cities of developing countries, including Kolkata, India. In this paper an assessment of the current level of road safety in Kolkata is made utilizing data obtained fr...

The objective of this research is to present a methodology to supplement the conventional traffic safety analysis techniques. This methodology aims at using computer simulation to animate and visualize accident occurrence at high-risk locations. It aids into developing the appropriate safety countermeasures for high-risk locations (e.g., intersections, curves, ramps). A computer accident simula...

We studied all traffic accidents to pedestrians under age 15 which occurred on the Island of Montreal during an eighteen months period. Data were collected from eleven hospitals and completed with accident police records. A spatial quadrat analysis, a Comparative Accident Index, and a comparative analysis of the means of different socio-ecological variables between high and low risk accident ar...

Decision makers working to improve transportation systems must constantly balance the need to improve roadway safety through infrastructure investment with constraints of available resources. We have explored the additional information available to transportation decision makers by integrating two independent datasets, traffic accident and roadway pavement condition data. The roadway condition ...

In this work, an intelligent traffic light controller that incorporates very important personnel (VIP) movement is presented. VIP movement often cause chaos or in the worst case accident at cross junctions. Traffic quantity, waiting time and siren intensity are the inputs to the system. The fuzzy logic tool box in Matlab 7.0 was used to simulate the system. The results obtained from running the...
