Northbound Santa Fe Drive Ramp to I-25 Ramp Metering Pilot Underway

July 29, 2014 - Metro Denver Colorado/CDOT Region 1 - DENVER – The Colorado Department of Transportation (CDOT) is looking at a variety of options to improve traffic flow and reduce congestion along the I-25 Corridor during peak travel times. CDOT

CDOT is implementing a ramp metering pilot on northbound Santa Fe Drive entrance ramp at I-25 to assess the potential operational improvements in this area.

The northbound (NB) Santa Fe Drive entrance ramp at I-25 experiences heavy congestion and delay throughout the day, primarily during the peak hours of travel. The I-25 merge comes to a stall and the queue backups extend upstream towards the I-25/Broadway exit during peak and often during non-peak hours. In an effort to improve the traffic flow and reduce congestion, the ramp metering pilot will test a variety of ramp metering strategies on the northbound Santa Fe Drive entrance ramp and will assess potential operational improvements.

The assessment began on Tuesday, July 29 and will continue for at least two weeks.  The testing scenarios include setting up the ramp meters at selected locations along the NB Santa Fe Drive near the entrance ramp and allowing ‘one vehicle per green each lane’ or ‘two vehicles per green each lane’ to improve operations.  We will be monitoring traffic flow, queue backups and traffic patterns and whether or not this pilot improves the traffic flows for motorists traveling in this area, including the I-25 traffic.
