Analysis of Performance Measures of UDOT's Traffic Incident Management Program

Many state departments of transportation (DOTs), including the Utah Department of Transportation (UDOT) are aware of the possible benefits of traffic incident management (TIM) but they have not been quantified to evaluate its cost effectiveness. Several years ago (year 2009) the Federal Highway Administration (FHWA) organized a Focus States Initiative for TIM Performance Management (TMI PM FSI) [1]. Utah was one of the 11 states that participated in this initiative. The initiative cited five benefits of TIM: 1) Increased driver and responder safety, 2) Congestion relief, 3) Effective preparation for larger-scale emergencies and disasters, 4) Public resources well spent to improve public’s life and 5) Reduced emissions caused by the delays created by congestion caused by incidents [1]. The TIM Handbook [2] states that incident management is defined as the systematic, planned and coordinated uses of human, institutional, mechanical and technical resources to reduce the duration and impact of incidents and improve the safety of motorists, crash victims and incident responders.” With this goal in mind, many states have begun implementing TIM and incident management teams are traveling through highways to minimize the impact of incidents. The TIM PM FSI identified three performance measures as the major performance measures that will be useful to all the stakeholders in this topic: • Reduce “roadway” clearance time: Time between first recordable awareness of incident by a responsible agency and first confirmation that all lanes are available for traffic flow • Reduce “incident” clearance time: Time between first recordable awareness of incident by a responsible agency and time at which the last responder has left the scene, and • Reduce the number of secondary crashes: Number of unplanned crashes beginning with the time of detection of the primary incident where a collision occurs either (a) within the incident scenes or (b) within the queue, including the opposite direction, resulting from the original incident. For this proposed study, we focus on the first two performance measures to start with because the first two performance measures are directly related to the effectiveness of having TIM teams on the road. In order to evaluate the effectiveness of TIM, it is necessary to identify the availability of data on these performance measures. The FHWA website on TIM knowledgebase [3] shows that out of the 11 states in the TIM PM FSI, only four states have begun some work (California, Connecticut, New York and North Carolina) as of February 5, 2017. As for interagency data exchange, Utah is reported as “limited.” Hence, there is a need to begin coordinating data exchange with the Utah Highway Patrol (UHP), so that UDOT will be able to evaluate the performance of TIM in terms of the two performance measures. By doing so UDOT not only will be able to evaluate its own TIM system’s performance but also significantly contribute to the knowledgebase on this issue nationwide through the TIM Knowledgebase program.
