Advanced Queue Detection Systems Installed at Four Work Zones in Nebraska Were Estimated To Cost $166,225 per Work Zone for a 6-Month Project on I-80.

Cost Subsystem
Roadside Detection (RS-D)
The system cost analysis was based on a typical AQD system including one CCTV camera, three non-intrusive detection, and two pairs (total of four) of PDMS. Based on an estimation of six-month…
