- Improved truck operation
- Short Elliott Hendrickson
- Truck Priority at Traffic Signals (December 2004)
The intersection of T.H. 169 and Laredo Avenue in Belle Plaine was selected as the test intersection. This location was picked because it did not have an existing isolated traffic signal without advance warning flashers and the truck volumes were high at about 2400 per day.
Three methods for improving truck operation were investigated:
The conclusion of this study was that operating traffic signals in a manner that improves truck operation provides benefits up to 25 times greater than costs and that other traffic using the same intersection will incur little or no additional cost and in most cases that traffic will experience improved operation as well.
