ITS control and surveillance devices location modeling to improve safety

Abstract

Traffic safety in rural area can be considered as an important source of worry among the many countries. Nowadays, transportation professionals widely use intelligent transportation systems (ITS) to address safety problems. However, in comparison of metropolitan applications, the rural ITS applications sill are not well defined. This paper provides a comprehensive survey on the all existing ITS safety solutions in the rural highways. In continuation, the study is mainly focused on the infrastructure-based control and surveillance ITS technology such as Crash Prevention and Safety, Road Weather Management and other applications that directly related to the reduction of frequency and severity of accidents.

The main objective of the present work is to develop an ITS control and surveillance devices locating model to achieve the largest safety benefit in the rural routes. In this research the updated ITS benefit and costs databases are used, and then the Integer linear programming is utilized as an optimization technique to choose the most suitable set of ITS devises.

Finally to demonstrate the effectiveness of the proposed methodology, a computational analysis was performed on a segment of rural highway in Iran.
