TRAFFIC SIMULATION MODELING TO INVESTIGATE THE IMPACT OF ON-STREET MICROBUS-STOPS ON TRAFFIC FLOW

Abstract

Curbside bus and microbus stops are very common on urban roads in Cairo and many other developing and developed nations. When a bus or a microbus arrives and stops at these bus stops, it obstructs the flow of upstream vehicles and thus reduces capacity of midblock section. This reduction in capacity depends on the bus frequency and dwell time of buses. Different types of bus/microbus stops like curbside stops, bus bays, queue jumpers and nubs have significant effect on traffic flow. In Cairo, most bus stops are like the curbside type. The main problem of bus stops is the presences of unscheduled stops, which become a usual behavior for Cairo microbuses.
