Dublin Road/Peterson Boulevard Intersection

Matrix was asked by the City of Colorado Springs to study this busy all-way, stop-controlled intersection with an elementary school on the southeast corner. The afternoon pickup from school caused backups and intersection congestion. Using Synchro software, Matrix created a model of the intersection and checked traffic volumes against traffic signal warrants in the Manual of Uniform Traffic Control Devices (MUTCD). Matrix then determined that a traffic signal should be installed at the intersection, along with curb and median realignments to shorten pedestrian crossing distances and create better north/south alignment through the intersection.

Matrix created conceptual design, preliminary design (30 percent), and final design (90 percent) documents through October 2018, when the City placed the project on hold. The project was reinitiated in April 2020 with a revised final design (90 percent) plans, specifications, and estimate package. The project was constructed in the fall of 2020.

Installation of the traffic signal enabled the intersection to operate more efficiently, and reconfiguration of the intersection to allow shorter pedestrian crossing distances meant that pedestrians were exposed for a shorter time, making the intersection safer to cross. The signal-controlled pedestrian crossing also permitted more parents to park in the parking lot on the northwest corner of the intersection and walk across to pick up students, thereby shortening the length of the vehicle queue along Dublin Boulevard.
