To protect pedestrians, bicyclists, and the quality of living environment, vertical and horizontal speed reduction devices (SRD) are often utilized to reduce the vehicle speed. SRDs not only contribute to reducing vehicle speed, but also redistribute the traffic flow due to the change of travel time which implies the residents have also to endure the inconvenience of SRD. To help evaluate the SRD installation, this study uses the traffic flow-speed-density relationship setting the minimum travel time as the objective function to establish a steady state traffic assignment model. Different traffic settings and SRD installation schemes are tested and evaluated which shows that the introduction of SRD is most significant when traffic outside the traffic calming zone is at high volume peak period. By proper choice of SRD type and installation scheme, through traffic outside the community cutting into the local streets can be significantly reduced.
