I-285 Westside Express Lanes - 680 locations for 2 days
February to April 2022
Arcadis selected Marr Traffic to collect traffic data throughout the length of the I-285 Westside Express Lanes construction area. The project included the collection of the following sets of traffic data:
• TMC Class Counts: 150 Locations for 6 hours per day and for 2 Days.
• Arterial Class Counts: 350 Locations for 48 Hours.
• Ramp Class Counts: 150 Locations for 48 Hours.
• Interstate Video Class Counts: 30 Locations for 48 Hours.
Marr Traffic utilized all of its experience and resources to undertake a project of this size, installing tube counters where safe and appropriate to do so, and cameras at all remaining sites. The data was then analyzed to provide classified turn movement counts broken down into 15-minute intervals with hourly totals and peak hour data, as well as speed and volume data also in 15 minute intervals and segmented into speed intervals. All data was delivered on time and on budget.
