Snow Plow Dashboard Camera 511 Winter Weather Advisory Info

Stage: Active

Campaign: Maintenance, Operations and Security

Approximately 160 snow plows assigned to Minnesota Interstate corridors will be outfitted with dashboard cameras to capture images of road conditions during winter weather events and serve the images through the plow truck AVL system to the 511 web site map. The geo-located and timestamped images will be set to self-delete from the 511 map after a short time (less than 1 hour) so that images on the 511 site stay current. ...more »

Feasibility of a Statewide Travel Demand Model

Stage: Active

Campaign: Policy and Planning

Many states in the US have statewide Travel Demand Models, not including Minnesota. The main purpose of these models is to predict all travel in the state, often including multimodal components. Currently, all Metropolitan Planning Organizations (MPO's) in Minnesota have their own regional models, with limited support and guidance from MnDOT. Ideally, MnDOT would play a larger role in tying these models together to a ...more »

Development of HOT access design methodology and guidelines

Stage: Active

Campaign: Traffic and Safety

A recently concluded project evaluated the effect of the MnPASS access design on the HOT lane mobility and safety. Although results were encouraging for both of the alternative design philosophies of Restricted Access (I-394) and Open Access (I-35W) it was pointed out that the optimal solution is somewhere in between. The project also created tools that assist in the design of each individual design alternative. These ...more »

Passing Lane Design Study

Stage: Active

Campaign: Traffic and Safety

Minnesota has not historically deployed passing lanes on 2 lane 2 way rural roads. Due to design guidance, that recommends a grade cross section that costs nearly as much as a 4 lane expansion. This research should investigate the acceptance of various cross sections (lane & shoulder widths, number of lanes, etc).

Validating an objective roadside tool to assess fatigue in snow plow drivers

Stage: RFP

Campaign: Maintenance, Operations and Security

NHTSA estimates that 40,000 injuries and 1,550 deaths are caused by drowsy driving each year in the United States. In 2012, 443 crashes were attributed to drowsy driving in Minnesota alone. Currently, an objective method to assess driver fatigue is not available and subjective assessments used in the past have proven to be problematic. Developing and validating an objective measure of fatigue is paramount for safety efforts, ...more »

Value of Trip Time Reliability to MnPASS Customers

Stage: Active

Campaign: Policy and Planning

In line with MnDOT goal of enhancing financial effectiveness, MnPASS provides great value to commuters but may not be well understood. Value for MnPASS is achieved through time savings, but also through travel time reliability and trip departure time flexibility. This has not been studied thoroughly. This work could be done as a social behavior study, namely on focus groups.
