Analysis of mixed traffic flow considering the differences of mixed situation of four-wheeled vehicles and motorcycles
Kazushi Sano, Hiroaki Nishiuchi
Road traffic that has been traveled in the developing countries is known as ignoring lane. It can be assumed that the speed of each vehicle becomes lower if the traffic condition is non-uniform and the speed of each vehicle vary. However, a current state is not able to express the speed differences of mixed traffic situation of four-wheel vehicles and two-wheel vehicles. The purpose of this study is to verify whether if the non-uniform traffic conditions, the speed decrease at the same level of density or not. The data recorded by video camera at 9:00 - 11:00 on September 29, 2009 in Hanoi city. The velocity-density relationship by the speed data and the position coordinate data are used to verify. Further, the calculation of the area per vehicle by Voronoi division and investigation of the relationship between velocity and area size will be considered. Create a traffic flow model by multiple regression analysis, and performs sensitivity analysis. The results in the transportation system that ignore the traffic lane will help to improve the capacity estimation. Moreover, the service level evaluation of traffic control infrastructure and design of transportation systems in developing countries become better
