Summary Information

In Colorado, a Truck Tip-Over Warning System was deployed on I-70 east bound just outside Idaho Springs to help prevent rollover crashes on sharp curves. The system consisted of two piezo weigh-in-motion (WIM) devices, traffic detectors, four fiber optic message signs, computer processing equipment and associated software, and a controller cabinet.

When vehicles were detected exceeding the maximum safe speed for their weight category, the warning system was activated and messages were displayed on otherwise blanked-out roadside message signs.

The low bid for the project was $446,687 (2002). The equipment list of the major components identified in the bid tabulation is presented in the table below.
