Evaluation of Effectiveness by Combining of Bus and Demand Responsive Transit Service Focusing Bus Route Network Configuration

This paper aims to show the impact on effectiveness which the bus service is combined with demand responsive transit (DRT). We present four mixed integer liner problems for design bus route network that maximizes the capturing amount of origin-destination (OD) flow and calculating the number of vehicles and mileage of DRT that carry flow which bus does not pass. The OD flow is estimated by population and facility distribution. Through three case studies, we observed that the combination of bus and DRT is economically advantage due to a linear concentration of demand distributions. Moreover, it shows that DRT system has advantages in an environmental indicator, and access movement caused by bus service contributes from a healthy viewpoint.
