Abstract:The function relationships between saturation flow rate and the phase lost time at the time of entering of large truck was analyzed through the establishment of microscopic traffic simulation model to further obtain the traffic capacity at signalcontrolled intersection of port road.The results of simulation reveal that the saturation flow value and heavy truck rate is in the functional relationship of inverse proportion while the phase lost time value and rate of heavy trucks is in quadratic function relationship.Practical examples show that the calculated value resulted by the method proposed is very close to the actual traffic capacity value without little deviation,which justifies the rationality and effectiveness of this given method.
