- Abstract
Intelligent Transportation Systems (ITS) such as Variable Speed Limit Systems (VSL) provide new methods and strategies for managing speed limits that also effectively deal with high traffic density and increase road safety. However, the positive effects of VSL are only true when drivers adjust their speed according to VSL indicators, and this compliance is influenced by many factors such as demographics, drivers' knowledge of multi-lane highways, and their driving behaviors such as adhering to their driving lanes and speed limits and avoiding overtaking, aggressive and irresponsible driving behaviors. Thus, in order to obtain more insight into the effectiveness of implementing the VSL system in the Kingdom of Saudi Arabia (KSA) and the extent of Saudi drivers' compliance with it, a quantitative study was conducted through a field survey on a random sample of 400 Saudi drivers to describe their behavior towards VSL in six multilane highways in Jeddah, KSA as well as linking their attitudes toward the frequent use of multi-lane highways, their natural commitment to speed limits, and their natural response to traffic congestion. Analysis of the data showed that there is an average familiarity of Saudi drivers with the multilane highways, and there is a moderate tendency to lane-changing and exceeding the specified speed. Also, the analysis showed that Saudi drivers' attitude towards VSL is not governed by socio-demographic characteristics where the majority of drivers have similar responses toward VSL systems regardless of their gender, having a driving license, nationality, or educational level. In conclusion, the results showed that there are significant negative impacts of the drivers' familiarity with multilane highways, their response lane changing under traffic congestion, and their lack of commitment to speed on their attitude towards VSL, where drivers' response lane changing under traffic congestion has the strongest effect, followed by drivers' lack of commitment to speed and finally followed by drivers' familiarity with multilane highways with the least effect. The researcher recommends expanding the scope of the research to include other multilane highways in all regions of Saudi Arabia such as Dammam, Riyadh, etc. in a way that adds comprehensiveness and generality to the results of this study.
