摘要：	The paper compares two methods of modelling the relationship between arterial travel speed and traffic flow. The "Highway Capacity Manual" method relies on estimating delay at individual intersections and requires a lot of detailed input data. The model developed by the Centre for Transportation Studies (CTS) in Singapore requires only two input parameters: intersection spacing and minimum signal delay. Both models show similar trends in travel speed but the HCM method generally predicts lower speeds for uncongested traffic. The Singapore survey data show that arterial running time per kilometer depends on flow rate as well as on intersection spacing. Suggestions are made on how to improve the existing models by using more precise definitions of arterial flow, capacity and running time. It seems that aggregate models such as the CTS model are more appropriate for planning applications when detailed information on signal timing is not available.
