Improving Traffic Safety through Traffic Accident Risk Assessment

چکیده

The continuous development of sensors and the Internet Things has produced a large amount traffic data with location information. improvement safety benefits from availability accident data. Managers can patrol control relevant areas in advance limited police resources, according to short-term predictions. As result, possibility accidents be reduced, level improved. traditional approach prediction relies too much on subjective experience managers. Inspired by deep learning technology field computer vision, this study first divides road network into regular grids takes number each grid as pixel value an image. Then, based bi-directional ConvLSTM U-Net densely connected convolutions (BCDU-Net) is proposed. This method mines information hidden introduces further extract spatial-temporal features contained sequence. Thus, issues gradient disappearance model over-fitting caused training avoided. Finally, simulation experiment carried out historical Yinzhou District, Ningbo City. Results show that BCDU-Net better accuracy precision than other models three sets: motor vehicle accidents, non-motor single-vehicle accidents. Therefore, more suitable for good application prospects improving safety.

Development of Intersection Traffic Accident Risk Assessment Model

Traffic accidents at intersections in urban area are the most common and take a majority of the accident toll. Analysing and generating counter measures has been the major task for traffic safety officials and engineers. Without knowing the safety implications of the counter measures, the task normally concentrates on tackling accidents reflected in historic accident data. As more demand for tr...

[Smog and traffic accident].

Some measures to counter car accident have been taken from various angels in recent times, while their epidemiological consideration has not sufficiently been given. The presentation here is a study on the latter problem. Three elements have to be taken into account when car accident is to be investigated epidemiologically; first, car traffic itself, secondly what is related to main constituent...

Improving Safety and Security by Developing a Traffic Accident Prevention System

This research aims at developing accident prediction models to improve freeway safety. Also by reducing incident related congestion on freeways, response and evacuation times would also be reduced in emergency situations. There are considerable amounts of data that are collected and stored for ITS applications. This data includes speed, volume and occupancy provided by loop detectors. Most of t...
