Abstract Speed-flow equations have been developed for use in travel demand models to accurately predict the speed of traffic on urban roads. However, in urban environments the corresponding correlations are quite complex since they are influenced by relatively short road segments and signalized intersections resulting in interrupted traffic flow. Hence, networks, traffic and control strategies represent influencing factors with respect to the speed-volume relationship. In this context, the adequate length of a lane is a basic condition for a lane to realize its full capacity. Thus, this paper focuses on the investigation of the impact of different lengths of urban road segments on the speed-volume relationship by means of a simulative approach. The impact of both reductions and extensions of an urban road segment with respect to statistically significant changes in speed values under undersaturated and saturated traffic conditions will be presented.
