About this file
The document is a Technical Score Sheet for Freeway Data Collection Sensors, prepared for the Utah Department of Transportation (UDOT) through a Request for Proposal (RFP). The solicitation seeks qualified vendors to provide non-intrusive freeway traffic data collection sensors, with a comprehensive evaluation process that scores potential vendors across ten key technical categories including references, physical properties, cable and connectors, cabinet equipment, installation, software, configuration, detection accuracy, data reporting, maintenance, warranty, and product support. The contract is structured for multiple awards with a 5-year term and no renewal options, aiming to procure detection systems capable of collecting vehicle speed, lane occupancy, count, and classification data across all travel lanes.
The scoring sheet reveals a detailed technical evaluation methodology with a total of 760 possible points, encompassing critical performance metrics such as sensor ruggedization, environmental resilience, cable connectivity, installation ease, data accuracy, and technical support capabilities. While no specific pricing information is included in this technical scoring document, the comprehensive evaluation suggests UDOT is prioritizing technical capability, reliability, and comprehensive performance over lowest-cost solutions. The solicitation encourages vendors to submit innovative approaches and additional features beyond the minimum requirements, indicating an openness to advanced technological solutions in traffic data collection sensor technology.
