MetroSolutions Traffic Signals

Ardurra delivered traffic signal timing services for 96 intersections across Houston's East End, Southeast, North, and Downtown light rail corridors, developing sophisticated traffic signal logic for light rail vehicle interactions with traffic and railroad gates. The complex project required integration of multiple transportation modes while optimizing traffic flow and safety throughout Houston's expanding light rail network.

The team conducted extensive Synchro/SimTraffic simulation modeling to develop optimal AM/PM/OFF peak signal timing plans while programming NextEdit databases and conflict monitors. Comprehensive testing included laboratory simulations of light-rail operations at each intersection, ensuring seamless integration before field implementation.

Key Traffic Signal Services:

• Developed traffic signal timings for 96 intersections across four Houston light rail corridors, integrating multiple transportation modesCreated sophisticated signal logic for light rail vehicle

• interactions with traffic signals and railroad gate operations

• Conducted Synchro/SimTraffic modeling developing optimal AM/PM/OFF peak timing plans supporting corridor efficiency

• Programmed NextEdit databases and conflict monitors ensuring safe, coordinated operations across rail and vehicular traffic

• Performed laboratory testing simulating light rail operations for each intersection before field implementation

• Prepared detailed City field books, including phasing diagrams, database programming, and audible pedestrian programming specifications

• Conducted field testing and fine-tuning, attending intersection turn-on events and optimizing signal operations through cabinet burn-in review

The signal timing implementation demonstrates advanced traffic management expertise while supporting Houston's multi-modal transportation objectives. Comprehensive testing and coordination processes ensured safe, efficient operations across light rail corridors while maintaining optimal traffic flow for vehicular, pedestrian, and transit users throughout the urban transportation network.
