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.

Consistently meeting infiltration requirements of NPDES permit and permanent storm water management maintenance. Developing guidance and inspector tools will ensure constructed infiltration systems perform as designed and expected. This enhances financial effectiveness by doing something once, reduces frustrated communications due to why the BMP failed to perform, and insures the BMP will continue to function at the lowest possible costs to maintenance operators.

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.

There is more emphasis and desire for MnDOT to minimize traffic impacts relating to construction projects placed on system users. To effectively doe this, we need to continue to refine and improve the tools the improve our capabilities of analyzing the trade offs made between minimizing Road Users Costs and Construction Costs. This project could help us move us toward improving our effectiveness in balancing these tow competing goals.

Generating Traffic Information from Connected Vehicle V2V Basic Safety Messages

NHTSA published a notice of proposed rule making that will require all new cars as of some model year to broadcast a basic safety message (BSM) using Dedicated Short Range Communications (DSRC). The BSM will contain information such as the car's location, speed, heading and acceleration. This will enable a car to know where the surrounding cars are and avoid collisions. Installing DSRC roadside units will allow MnDOT ...more »

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

Travel times and end of queue information are important in work zones for safety and mobility, and knowing queue lengths at traffic signals could potentially enable smarter traffic signal control. Listening to vehicle BSM broadcasts is a means to gain early benefits from connected vehicles. Other vehicle to infrastructure connected vehicle applications will require additional capabilities in the car beyond what NHTSA is requiring, whereas generating traffic information from BSMs will be a possibility in the nearer term when vehicles may only have the vehicle to vehicle BSM broadcast capability on board. A literature search should be performed to determine what has already been done by others.

Research Objective

To develop a guide that can serve as a comprehensive information source on effective practices for converting severely distressed paved roads to acceptable unpaved surfaces.

The main benefit of this project will be the ready availability of a comprehensive guidance document on converting severely distressed paved roads to acceptable unpaved surfaces. No such document currently exists. The guide will aid in more effective selection of candidate roads for conversion, more effective conversions, and more effective communication with the public on how and why a conversion is taking place. The guide will allow for appropriate management of road maintenance funds and will serve as the basis for road conversions being accepted as another pavement management tool.

Using compost containing source separated organic material to reduce runoff at MnDOT sites

Minnesota Statute 115A.551 calls for reaching a 50% recycling rate in the metro area and 35% in greater Minnesota. In the Twin Cities Metro Area, organics recovery is currently between 3 and 6%, with a goal of 9-15% by 2030. Source separated organic material is separated from other wastes at the source, rather than at mixed municipal solid waste transfer stations. Source separated organic material is generally transferred ...more »

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

MnDOT could realize cost savings, acquiring SSOC directly from compost facility operators. Compost has been shown to be more effective than traditional BMPs such as hydroseed in soil stabilization, runoff/solids/nutrients/metals loading, and vegetation establishment. Furthermore, composting presents a closed loop process, which helps actualize MnDOT’s goals of becoming more sustainable.
