Downtown Signal Optimization

The Signal Optimization project element includes upgrading signal detection, controllers, and other hardware as well as conducting analysis and optimization of the entire downtown signal system. This part of the project has two main parts: signal modification and automated traffic signal performance measures (ATSPM) upgrades.

The signal modifications component involves upgrading the signals directly on Higgins Ave, Front St, and Main St. These signals will be designed to align with the new lane configurations, protected bike lanes, and intersection layouts associated with the corridor changes to each of these roadways.

The signal ATSPM upgrades expand beyond just these three roadways and will encompass 15 additional signals in the Downtown Missoula area. These upgrades will involve installing equipment on the signals that will allow collection and analysis of high-resolution data to optimize signal timing and improve the overall system performance in the downtown area.These upgrades will not only help in the near term but will allow tracking of this data in the future to determine how to keep the signal timing and performance optimized.

  • Share Can the city work on a better solution for the Madison/East Broadway intersection, just as a protected left hand turn for the north/south traffic? The blinking yellow coupled with south bound lanes being allowed to turn left or straight causes a dangerous situation for everyone. This includes pedestrians crossing E Broadway because those turning left are paying attention to traffic and not people crossing. on Facebook Share Can the city work on a better solution for the Madison/East Broadway intersection, just as a protected left hand turn for the north/south traffic?

    Thank you for your question!  This intersection has been identified to receive upgrades to the signal timing to improve safety for all users at the intersection. We have passed your comments on to our traffic engineers as they work through the design for the signal optimization project element.

    We appreciate your engagement,

  • Share Hi there! I'm wondering/hoping if this project will address pedestrian use of signals. It really bothers me that the hip strip traffic lights require pedestrians to push a button to cross at all times of day. Often tourists don't know to do this, and are frustrated to have to wait through another light change. It's also frustrating for regular users to have to sprint to push a button, and sometimes the buttons don't work. There is really heavy pedestrian use in this area during the day, so it feels unneccesary. It also contributes to a feeling that this is a driving area, and pedestrians are an anomaly, which is not true. Automatic walk signals would make the neighborhood much friendlier for those on foot!

    Thanks for your question about Signal Optimization! The Project Team is actively exploring multiple solutions as we work on signal upgrades in downtown Missoula. As the team plans the signal upgrades, they are reviewing optimizations like 

    • ensuring a WALK signal is provided every cycle without requiring the push button activation 
    • upgrading push buttons to meet ADA compliance
    • giving pedestrians a 3–7 second head start before parallel vehicle movements receive a green light 
    • signal timing for all users, to ensure the timing meets current standards of safety.  

     

    Some aspects of optimization, like ADA compliance, are required as part of the grant we received for the project, but other aspects aren't finalized yet. We will have more information at the Open House we're planning for this fall (details to be announced soon!). We hope you'll join us!  

     

    Thanks for taking an interest in the Downtown SAM project,
