Analysis and Evaluation of Speeding Characteristics - Related Crashes in Eastern Province KSA
Speed study and evaluation is a common traffic investigation required for traffic safety studies by public-sector and local government agencies. The recommendations from the speed study can have a direct impact to how the traffic system is planned. This paper presented analyses which addressed different aspects of speed characteristics on selected sites along two corridors in Eastern Province in Kingdom of Saudi Arabia (KSA). The study was conducted by ARAMCO Chair for Traffic Safety at the University of Dammam. It provides in depth investigation and analysis of speed along the two corridors: King Fahd highway and GCC Expressway. A sample of study was collected from 88 locations. Analysis and evaluation of speed from these locations showed that some sites were suffering from a speed problem. The driver compliance with speed limit is assessed by a comparison of the 85th percentile speed with the posted speed limit. The observed speeding trends show that drivers overall tend to exceed the posted limit. It was found that the percentage of drivers exceeding the speed limit varies widely from site to site. On average the share of drivers exceeding the speed limit is about 20%. The posted speed limit in some locations may not be appropriate according to the limited collected data on this study. The 85th percentile speed should be selected as a primary factor in determining the posted speed limit for any homogenous roadway zone. To understand the correlation of crash occurrences with speed, data was manipulated using ArcGIS software to link the crash numbers associated with 85 percentile speed categories. It can be observed that generally the higher the speed the greater the number of crashes.
