  Utilize the existing ATM infrastructure on I-94 to test a Vehicle-2-Infrastructure (V2I) and Vehicle-2-Vehicle (V2V) safety application to reduce crashes. The project would develop and test a vehicle-based V2V crash avoidance technology. For vehicles not equipped with V2V communications, a system would be developed utilizing roadside equipmenet that would detect individual vehicles and broadcast a basic safety message ...more »

  Utilize the existing ATM infrastructure on I-94 to test a Vehicle-2-Infrastructure (V2I) and Vehicle-2-Vehicle (V2V) safety application to reduce crashes. The project would develop and test a vehicle-based V2V crash avoidance technology. For vehicles not equipped with V2V communications, a system would be developed utilizing roadside equipmenet that would detect individual vehicles and broadcast a basic safety message to other vehicles. The safety message could be relayed to the motorist through at smart-phone based warning system.

  This would be a phase 2 project that would reevalute the Traffic Information & Condition Analysis System (TICAS) developed for the RTMC. This tool was developed several years ago to help extract RTMC freeway data and develop performance measures for the metro freeway system. The goal of this research would be to make enhancements and modifications to the software now that it has been in use for a few years.

  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 ...more »

  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.

  MnDOT has been a leader in investing funding in new technologies to help reduce congestion and improve safety. Once such example is the Active Traffic Management (ATM) system on I-35W and I-94 which includes intelligent lane control signals (ILCS) spaced every half mile over every lane to warn motorists of incidents or hazards on the roadway ahead.

  MnDOT has been a leader in investing funding in new technologies to help reduce congestion and improve safety. Once such example is the Active Traffic Management (ATM) system on I-35W and I-94 which includes intelligent lane control signals (ILCS) spaced every half mile over every lane to warn motorists of incidents or hazards on the roadway ahead. The ATM system is used to warn motorists of hazards ahead through the use of icons that warn motorists when a lane is obstructed. Variable Advisory Speed Limits are also used to warn motorists of congestion ahead on the mainline, however, one area the system could be improved is in providing warning of queues or shockwaves that effect a single lane of traffic. One example would be WB 94 approaching the ramp from NB I-35W where shockwaves in the right lane lead to crashes within the I-94/I-35W interchange. Another example would be on SB I-35W approaching Hwy 62 where queues backing up from Hwy 62 impact the right most lanes of I-35W which has contributed to crashes on the corridor. This project would develop a system that could identify potential queues on the mainline and then send a warning to motorists upstream by utilizing the existing ATM infrastructure.
