4. Baseline and 35th Street Traffic Signal Warrant Study University of Colorado Boulder
WHAT DID WE LEARN?
Traffic signal not warranted today
Traffic signal warrants will be nearly met in future based on volume and delay
Bus transit access, crash mitigation, and pedestrian crossing considerations suggest a traffic signal will be beneficial
Traffic signal will require modification to Frontage Road access at 35th Street

SUMMARY
Both Options 1 and 2 will:
Provide safe and efficient transit access onto Baseline
Mitigate broadside crash potential on Baseline at 35th
Result in traffic rerouting on the Frontage Road that is easily accommodated by intersections at 32nd and 37th
Have minimal impact on emergency service response time
