Road Weather Messaging on Dynamic Message Signs (DMS)

Nearly 300 DMS are deployed across the state and are used for displaying real-time information to warn motorists of incidents, roadwork or congestion downstream that may be a potential safety hazard or may cause delays. When it comes to weather related messages, MnDOT has limited DMS usage to blizzard warnings or unexpected/isolated conditions that make catch a motorist by surprise. Concerns over displaying weather ...more »

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

Benefits would be to develop an automated system for weather related messages that could potentially improve safety but also ensure weather related messages are timely and accurate which would improve customer trust in the messaging.

Private Contractors -Proper use of Temporary traffic Control Devices and Signs

After noticing numerous private contractors, working off of state highway shoulders and right of ways, with improper, or, lack of, temporary traffic control devices, or signs, I reached out to other employees, for their opinion, and, found out I was not alone. After consulting supervisors, TGS's, in both, maintenance, and construction, I could not find a clear answer on who enforces this area. I contacted a safety director, ...more »

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

more and more private contractors, are working on / off state highways, and right of ways, without the proper knowledge / training along with a lack of enforcement, creating a high risk for accidents.

I feel a positive educational approach, rather than, strictly, enforcement / fines, would result in a higher compliance rate, and, it turn, safer highways for all.

Implementation of New Guidelines in Tightening Large Anchor Bolts of Supports for Signs & luminaires

To implement the large anchor bolting tightening guidelines and specifications derived from the results of the current research project: "Re-tightening Large Anchor Bolts of Support Structures for Signs and Luminaires", which will be completed by the end of June 2018. This implementation project will include the tasks to generate workshop materials and three to four web-based training videos in anchor bolt tightening ...more »

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

The loose nuts in over 19% of large anchor bolts of the overhead sign and HMLT support structures has created MnDOT maintenance and inspection problem. AASHTO and FHWA guidelines allow DOTS to inspect OH supports and HMLT at the frequency of 5 years. With so many loose bolt nuts, it will need almost annual inspection for over 2000 OH signs and almost 500 HMLT. This also causes the public safety concerns. The results from the current research project basically has pin-pointed the causes of the loose nut problems and following the proposed guidelines and specifications in construction and maintenance can help in eliminating or minimizing this kind of problems. This will decrease the needs for more inspections and maintenance work and save MnDOT costs in traffic control, bolt inspection and retightening, and all related work. It will also improve the public safety in the loose bolt nut concerns. All state counties and cities can also be trained and benefited from this.

Lowrey Tunnel Communications System

When employees are working in the plenum space above the road inside the tunnel they have no ability to communicate with one another which poses a significant risk should an emergency occur inside the tunnel while employees are working. A communications system with radios & repeaters would make work much safer and provide piece of mind for employees while working so they can focus on the task at hand...

Enhancement and Integration of the TeTRIS and TICAS Freeway Performance Tools

This project would integrate the TeTRIS and TICAS Freeway Performance Tools into one system. The Traffic Information & Condition Analysis System (TICAS) was developed for the RTMC several years ago to help extract RTMC freeway data and develop performance measures for the metro freeway system. TeTRIS is currently being developed to be able to monitor travel time reliability on metro freeways. This project would combine ...more »
