"VALUING ROAD TRAFFIC FLOW PERFORMANCE FOR TWOWAY ROADS"

Various combinations of motorized vehicles were stated in advancement of model and the results of the developed modal bring certain guidelines to improve the traffic flow characteristics in the urban areas under mixed traffic conditions and significantly limiting the percentage of Cars, Buses and Trucks within the range and result optimal operating speed in a given urban road facilities, for instance with 30% of (Bajaj and Trucks) and 10% of (Cars and Buses) and with 20% of Motor-cycle which is in all subconditions (except in third sub-condition) displays that the value for operating speeds are below 50 km hr-1 between 4m-12m lane width which are dominant combinations to be within the boundaries of facilities. Consequently, average operating speed are majorly be determined by percentage of traffic volume and then with the lane width and additional factors has impacts under mixed traffic conditions.
