[ARCHIVED] Light-timing changes improve travel on Plum Creek Parkway

Drivers traveling on Plum Creek Parkway should experience fewer delays now that traffic lights along the stretch have been retimed to account for new road segments and a redesigned interchange.

The Town aims to update traffic signal timings every three years to adjust for population increases or when a significant roadway improvement is made. In this case, Plum Creek Parkway was expanded to both the east and west last year as part of the Southeast and Southwest Arterial Connection Road projects. During the construction, the parkway’s interchange with Interstate 25 also was redesigned to a standard diamond interchange.

The improvements changed traffic volumes and distribution patterns in the area. So the Town recently worked with the Colorado Department of Transportation to update the timing of the traffic signals at these locations:

  • Plum Creek Parkway at Plum Creek Boulevard (Town-operated)
  • Plum Creek Parkway at Perry Street (Town-operated)
  • Plum Creek Parkway at Wilcox Street (Town-operated)
  • Plum Creek Parkway at northbound I-25 ramps (CDOT-operated)
  • Plum Creek Parkway at southbound I-25 ramps (CDOT-operated)

  • Three different timing plans were developed to best match the average traffic volume and patterns along the corridor – one for the morning peak period, one for the evening peak period and the final for the off-peak period. The plans were implemented March 18; then, traffic was watched, and minor adjustments made. The changes led to improvements during nearly all times of the day in both directions.

    Westbound drivers in particular should experience a noticeable difference. Before the changes were implemented, it took 2 minutes, 15 seconds to travel the corridor during the morning peak period, 2 minutes, 23 seconds during the evening peak period and 2 minutes, 9 seconds during the off-peak period. Those times were improved to 1 minute, 25 seconds,
    1 minute, 50 seconds and 1 minute, 19 seconds, respectively – representing positive impacts of 37, 23 and 39 percent.

    Eastbound, it previously took drivers 1 minute, 32 seconds to travel the corridor during the morning peak period,
    2 minutes, 2 seconds during the evening peak period and 1 minute, 39 seconds during the off-peak period. Now, it takes
    1 minute, 36 seconds during the morning peak, 1 minute, 32 seconds during the evening peak and 1 minute, 38 seconds during off-peak times. The differences in the morning and off-peak times are small, but the evening peak saw a
    25 percent improvement in traveling times as a result of the changes.
