| 摘要： | Arizona Department of Transportation (ADOT) recognizes that evaluation of highway safety from a corridor perspective provides different benefits than the spot analysis used up until now. The project programming procedure at ADOT accepts a quantitative ranking of safety considerations for each potential project in assessing a project's benefit. ADOT highway safety engineers are in need of spatial tools that analyze the crash database, providing spot analysis, corridor analysis, and the quantitative output desired by transportation planners. FHWA has endorsed the Corridor Safety Improvement Program (CSIP) process as a methodology for gathering multidisciplinary input from enforcement, education, and emergency medical services (EMS) personnel to supplement the engineering point-of-view and arrive at better decisions from a multi-objective perspective. NHTSA has a Safe Communities initiative, which promotes the same type of multi-disciplinary safety team (MDST) concept towards improving safety in communities (as opposed to corridors). This paper explores Arizona's ability to adopt the FHWA CSIP model and adapt it to work within the institutional, jurisdictional, resource, and funding framework of Arizona. The results of the project indicate that: ADOT is only one of several state agencies that have a hand in promoting and providing highway safety; All agencies that endeavor to improve highway safety should collaborate and focus on high-risk corridors to effectively develop multi-objective action plans and implement the most appropriate countermeasures; The identification of high risk spots and corridors can be greatly assisted using contemporary GIS spatial analysis tools and the Accident Location Identification Surveillance System (ALISS) crash database; The ADOT photo log and GPS-derived corridor centerline files add a unique level of comprehension of safety problems by showing signing/striping/guardrail conditions in plan and profile views overlain with ALISS crash history and a link photo log image of the roadway. |
