The Illinois Tollway selected SRF to provide intelligent transportation system (ITS) design and construction management services through a five-year on-call contract. SRF is leading the design of both new ITS infrastructure and retrofits to existing systems. Tasks have included:
- Identifying and filling gaps in CCTV coverage based on crash report analysis. SRF developed a methodology to identify where gaps on the system could be filled to create the largest impact to the system based and developed a CCTV Gap Analysis Concept Report. SRF then prepared the PS&E documents for the camera installation.
- Preparing the plan, specification and estimate (PS&E) documents for the installation of two virtual weigh-in-motion (VWIM) stations including associated infrastructure repairs.
- Preparing PS&E documents for systemwide ramp queue detection warning replacement and modernization including replacing flashing beacons and CCTV cameras.
- Preparing PS&E documents for toll plaza improvement to create an all-electronic tolling (AET) zone for ramps at the I-294 and I-55 interchange. The Roadway Traffic Control and Communications Manual for the Illinois Tollway (MOT) required that toll collection for the ramps remain functional at all times.
- Preparing PS&E documents to implement sustainable improvements at Plaza 41 including Level 3 Electric Vehicle charging stations, shore power spaces for semi-trucks, and solar arrays.
- Developing a technical memorandum to evaluate technology related solutions to mitigate unauthorized shoulder stopping, standing, and parking on the shoulders along the ramps near O’Hare Airport including order of magnitude costs.
- Developing a concept report for structural maintenance activities, security upgrades, and FAA lighting upgrades for the Tollway’s communication towers.
For this contract, SRF teamed with a Disadvantaged Business Enterprise (DBE) to form a mentor-protégé partnership.
