Speed Impacts on Complete Streets Elements, Phase II

Minnesota State University has recently completed related complete streets research that explored the effects of various roadway cross-sectional characteristics on driver speed selection in urban and suburban areas across Minnesota. This research resulted in a series of speed reduction factors (SRF) for various roadway cross-sectional elements and related guidance as to how those elements reduce speeds. However, some important questions remain. In particular, there is interest in understanding how driver speed selection varies when non-motorized users are present. There are also areas from the initial research that warrant further investigation, such as how driver behavior varies based on median dimensions, the presence of curb and gutter, and the degree of parking activity along a corridor. This study aims to address these gaps by investigating how these elements affect driver speed selection through a series of field studies at 16 sites throughout Minnesota. The results of this study will provide additional guidance that furthers efforts of the Minnesota Department of Transportation (MnDOT) and local road agencies.
