A TRAVEL TIME ESTIMATION MODEL OF PRIVATE CARS IN URBAN ARTERIAL ROADS BASED ON HETEROGENEOUS TRAFFIC

Nowadays, many cities in developing countries such cities in Indonesia are facing serious traffic problems due to the motor vehicles growth has increased rapidly. In this situation, the vehicles made maneuvers and behaviors that are insufficient for the condition. In example, light vehicles and motorcycles have conducting zigzag maneuvers, creeps up slowly to the front of queue when the signal are red, impedes traffic flow by disturbing the star of other vehicle behind, etc. (Chandra et al, 2003; Zakaria et al. 2011, Hustim et al., 2011). Also, the vehicles have inconsistency or indiscipline to use their lane (Aly et al., 2011, 2012; and Hustim et al., 2011). Under the circumstances, the motor vehicles behavior has changed from homogeneous situations to heterogeneous conditions. The last traffic behavior type has reduced the vehicle speeds and the other modes, also made more congested (Zakaria et al. 2011). In further, travel time of the vehicles on urban roads under the traffic situation become worse.
