SUMMARY:

An ordinance authorizing the award of a construction contract for the Traffic Signal Installation Package B, a 2018 Tax Notes funded project, in the amount of $591,989.00 and authorizing payment to D&G Energy Corporation to construct three traffic signals located in Council Districts 3 and 5.


BACKGROUND INFORMATION:

Traffic signals improve the efficiency and safety of vehicular and pedestrian traffic at an intersection and provide for the orderly movement of vehicles, bicyclists and pedestrians. New traffic signal projects also include construction of sidewalks and curb ramps when necessary ensuring pedestrian signals are accessible to all users of the transportation system. In general, the following metrics are reviewed when determining if a signal is an appropriate traffic control device:

* Traffic volumes approaching the intersection
* Crash history and contributing factors
* Land use characteristics such school crossings
* Proximity of nearby signals
* Approach speeds and sight distance
* Intersection configuration and design

If the signal is warranted and recommended for installation based on the above mentioned metrics, funds will be requested through the annual capital project budget process. Typically, the installation of a traffic signal takes approximately 18 months to complete the survey, design, environmental review, utility coordination and relocation, bidding and construction. Traffic signals are also sometimes installed as part of new development.
