THE RELATIONSHIP OF SAFETY AND COMPONENTS OF TOLL ROADS SERVICE
The components of good services on toll roads include comfort, safety, traffic flow without congestion, and low cost. Indonesia uses Minimum Service Standard to provide the good service on toll roads. Whereas Korea uses Level of Service and ITS to measure the service on toll roads. With a different implementation of service on a toll road, there is a different result on safety. This research will show exactly which component has a big effect to influence the road safety based on Korean and Indonesian experts and shows the weight of that components in affecting the road safety. This research uses descriptive quantitative study with questionnaire data collection techniques. The questionnaire results will be analyzed with Structural Equation Modeling (SEM) method by using AMOS program. The analysis result shows that the contribution of toll road service based on Korean expert data (24.1%) is larger as compared to Indonesian expert data (21.4%) in improving the road safety. The most important component of toll road service to improve the road safety based on Korean expert data is toll road condition (90.8%), and the second is safety tools (85.6%). On the other hand, the most important component of toll road service to improve the road safety based on Indonesian expert data is safety tools (74.2%), and the second is toll road condition (54%). Based on both result, the component that has the biggest affect on road safety is human factor, and the second is the road; ITS is also very important to be applied on the toll road to provide a real-time information service, since using ITS minimize the human factor and monitor the road condition in real time.
