Evaluation of MnPASS Access Changes on I-394

A previous project from the UMN entitled "Evaluation of the Effect MnPASS Lane Design has on Mobility and Safety" developed recommendations for designing access spacing on HOT lanes. Based on the recommendations of this study, MNDOT restriped the I-394 MnPASS lanes to have a more open access design. This project would measure the effectiveness of these changes to ensure that a more open access design has not had any ...more »

Why is this a priority and what are the benefits for the State/County/City? :

MnDOT and the Metropolitan Council have recommended additional MnPASS lanes for the region in future years because MnPASS is a cost-effective strategy for managing congestion, using existing road capacity to reduce travel times on some of the busiest roads in the metro area. This project would ensure that the recommendations from the UMN study entitled "Evaluation of the Effect MnPASS Lane Design has on Mobility and Safety" are appropriate for not only the existing MnPASS corridors but future designs as well.

Implement a Bluetooth Based In-Vehicle Message System to Alert Motorists in Workzones

A prototype system was previously developed to investigate the feasibility of using in-vehicle messages to heighten drivers’ awareness of safety-critical and pertinent work zone information. The previous effort focused on using an inexpensive technology based on Bluetooth Low Energy (BLE) tags that can be deployed in or ahead of the work zone. An Android smartphone app was developed to trigger non-distracting, auditory-visual ...more »

Why is this a priority and what are the benefits for the State/County/City? :

The proposed approach could establish an alternative to automatic speed enforcement to potentially change the behavior in work zones by providing dynamic work zone information. This project will prepare us for a later field operational test. The outcome of this project will allow MnDOT to provide audible work zone information to drivers through a smartphone or a vehicle’s infotainment system. This project will provide guidelines for engineers and operational staff to determine the placement of tagged landmarks at work zones for triggering in-vehicle messages. The smartphone app can potentially be integrated with a 511 system or other navigation apps to dynamically receive relevant work zone information.
