Major improvements were made on I-35W in recent years including reconstruction of the Crosstown Commons, implementation of the first priced dynamic shoulder lane in the country, construction of low-cost/high-benefit capacity improvements, and the deployment of Active Traffic Management with the use on lane control signals and advisory variable speed limits. These improvements have been in place for about 3 years and there is a need to conduct an evaluation of the crash benefits these improvements had in order to learn how these benefits could be utilized on other corridors. Due to major changes in traffic patterns because of the Crosstown reconstruction, a more complex statistical analysis will need to be conducted to determine the safety benefits along the corridor. For example, the section of 35W with the PDSL experiences higher levels of congestion due to the removal of the Crosstown bottleneck. Crashes on the PDSL stretch have increased but is this due to the geometrics of the corridor or the increased congestion in this area caused by the removal of the major bottleneck to the south. The consultant would be used to conduct a statistical analysis of the crashes compared to the volumes and congestion levels on the corridor and compare this to other congested corridors in the metro.
