Transportation safety professionals strive to build a system on which no street user can be severally or fatality injured on. To accomplish such a safe system, it is necessary to effectively harness all the core protective opportunities provided by the system. Despite the increasing consensus that this needs to be thought of as a systems problem, the considerations for each of these layers of protection are siloed, and many of the protective features are evaluated in terms of potential lives saved due to a specific improvement. The proposed research will examine what happens when we no longer assume each of the individual components holds a desirable level of protection for a certain circumstance, but that they contribute to a larger joint entity (i.e., the system) that can exhibit the required characteristics or traits (i.e., safe). The conjecture here is that there is a set of protective features that can jointly fulfill the promise of a safe system.
This projects aims to:
  • Determine whether kinetic energy is indeed a desirable feature that can be quantified across the different protective mechanisms of the system (e.g., roadway, vehicle, laws).
  • Analyze levels of the selected crash magnitude proxy (e.g., kinetic energy) that road users are exposed to across different parts of the network. This will be done by mode.
  • Develop a framework to quantify the overall protective capability of the system and will be benchmarked against the desired capability of the system, as established by the policy makers.
