• Abstract:
  The overall objective of this research was to study work zone accidents in New York State, with particular attention to the ; occurrence and mitigation of rear-end vehicle accidents. The specific objectives were to: ; - Recommend changes to the NYSDOT’s accident database system for more efficient management and analysis. ; - Conduct a detailed investigation of rear-end crashes in work zones and recommend measures that can reduce the frequency ; of these types of crashes. ; - Report on traffic exposure data and accident patterns / parameters to be incorporated into future NYSDOT accident data ; analysis. ; Task 1 focused on evaluating the current NYSDOT work zone accident reporting system, surveying practices used in other states, ; and providing recommendations for improvement. The results of this task revealed that the current NYSDOT work zone accident ; reporting system is the most comprehensive in the country. Further changes to improve the system were recommended based on a ; review of the literature and practices being implemented in other state agencies. ; The first part of Task 2 was focused on analyzing rear-en accidents in work zones that occurred in New York State between 1994 ; and 2001. Since data were available only on work zones that had accidents, truncated count data models were estimated to study ; the relationship between crash frequency and work zone characteristics. Ordered probit models were developed to study crash ; severity. ; The second part of Task 2 provides some corrective actions to reduce frequency of work zone accidents. These actions are ; primarily based on a review of the literature since information on changes made by NYSDOT at the project level was not available ; to the research team. ; The first subtask of Task 3 provided some recommendations to incorporate more project information to the work zone database ; either through adding more variables or including project information in a separate database that can be linked through a project ; identification number. The second subtask of Task 3 focused on various venues and approaches for obtaining exposure to traffic ; for various types of work zones. The final subtask of Task 3 focused on identifying parameters correlated with work zones and the ; county level.
