The intersection at Eldorado Parkway and Independence is currently operating as a 4-way stop. The federal Manual of Uniform Traffic Control Devices allows an agency to install a 4-way stop as an interim measure before a traffic signal can be constructed.
A traffic signal design is in progress for this intersection along with the intersection of Dallas North Tollway and Cotton Gin. We plan to let a construction project later in the year so that both signals are complete by the second quarter of next year.
Our database showed 6 crashes at Eldorado Parkway and Independence in 2007. The severity of injuries last year was very low because all vehicles were required to stop before entering the intersection. A traffic signal is not expected to reduce the number of crashes at this location. For example, during the same period in 2007 Eldorado Parkway at Preston Road experienced 28 crashes compared to the 6 crashes at Eldorado and Independence. The severity of crashes at a traffic signal is also typically greater due to the speed of the vehicles traveling through the intersection.
The City of Frisco reviews approximately 50 intersections each year to prioritize the need for new traffic signals. We look at crash experience and traffic volume to fund projects with the greatest need. The intersection of Eldorado Parkway and Independence was in the top 10 based last year and the design of the signal is currently moving along as quickly as possible.
I hope these comments help you understand the process we work through as a street intersection moves from a 4-way stop to a traffic signal.
