Estimated Costs for an Adaptive Signal Control System Using Max-Pressure in Minnesota Were Influenced by the Addition of Loop Detectors and Video Detection System Upgrades.
Twin Cities, Minnesota, United States
To implement the max-pressure signal timing technology, additional loop detectors would be needed to determine queue lengths at the signalized intersections. In addition to loop detectors, another option could be to raise the video detectors higher to have a better range of vision so they can better detect queues. Therefore, considering the unit costs of items required for max-pressure control system implementation at a total of 3,280 intersections in the Twin Cities Metro Area, the total system cost estimate would come to $69,961,900. The details of an estimated cost breakdown are shown in Table 1.
Table 1. Estimated cost breakdown for implementing Max-Pressure Control*
| Estimated Costs | Signal Quantity | Unit Cost | Total Cost |
| MnDOT Loop Detectors Extension | 635 | $32,000 | $20,320,000 |
| Hennepin County Detection Cameras | 460 | $12,500 | $5,750,000 |
| Hennepin County MaxTime Controllers | 460 | $2,545 | $1,170,700 |
| Other Agencies’ Loop Detectors Extension | 1093 | $24,000 | $26,232,000 |
| Other Agencies’ Video Detection System Upgrades | 1092 | $15,100 | $16,489,200 |
| Total | 3280 | $69,961,900 |
*Cost for loop detector is based on USDOT’s information for the cost of installing a loop detector with existing pavement per lane ($2,000, based on 2013 dollar value).
