Discussion of theoretical and practical challenges in developing high collision concentration location detection procedures

ABSTRACT

The resource allocation for conducting site investigation and implementation of safety countermeasures is determined based the results of high collision concentration location (HCCL) detection procedures. HCCL detection plays a vital role in prioritizing how government agencies utilize limited resources to improve the safety of the roadway system. However, there exists no universally accepted, specific method of detecting HCCL, and the resulting HCCL list can differ markedly depending on which HCCL procedures were employed to evaluate the traffic collision data. The objective of this literature review paper is to discuss both theoretical and practical challenges in developing HCCL procedures and their potential adverse effects. This paper also discusses how some of the challenges can be addressed with findings from recent studies.
