Abstract:

Despite the presence of properly signed and well-located runaway truck ramps, crashes involving trucks with overheated or otherwise failed brakes continue to occur downhill from the ramp locations. A recently deployed experimental truck warning system on Wolf Creek Pass on westbound SH160 shows some promise of effective crash reduction. The intent of this research project is to conduct observational before and after study at Wolf Creek truck escape ramps and evaluate feasibility of deployment of this system at all truck escape ramps in Colorado.

Implementation: A methodology to evaluate safety performance by direction using Colorado-specific crash prediction models for the mountainous environment has been developed. The effectiveness of a detection and warning system for runaway trucks can be quantified. The findings of this research have the potential to reduce runaway truck crashes in the mountainous environment in Colorado and elsewhere.
