Municipal Traffic Signal Operations Management and Engineering

City of Elgin

OBJECTIVE

Preserving safe and optimal traffic flow efficiently along busy streets through a traffic signal network can be challenging. By monitoring and directing traffic signal maintenance activities in Elgin, HLR assists in expanding and improving the traffic signal system network in this community.

PROJECT DESCRIPTION

To assist the City of Elgin with their traffic system management, HLR’s traffic engineering department addresses equipment damage and failure in a timely manner, deciding to repair or replace equipment due to age and/or damage due to vehicle “knock downs” or construction activities. This includes checking the traffic signal controller programmed databases (auto-compare) once a week for unauthorized changes, detection problems, and communication problems. Additionally, our team performs field checks of all traffic signals and flashing beacons to ensure all contract traffic signal maintenance is being properly performed and reviews traffic signal vehicle clearance and pedestrian timings on an ongoing basis.

The project also includes daily coordination with the City’s Electrical Maintenance Contractor to address and resolve maintenance issues. We investigate, resolve, and respond to complaints that the City receives concerning traffic signal operations.  Our team is also performing an inventory of traffic signal equipment and developing and implementing optimized traffic signal timing plans for various time periods. HLR also assists the City in review and budget decision-making for future traffic signal improvements.

Scope of Work

• Traffic signal operation and database monitoring
