Analyzing the Effectiveness of Enhanced Penalty Zones and Police Enforcement as Freeway Speed-Control Measures

Speeding has been well recognized as an important contributing factor to traffic crashes. Past research also indicates that driver behavior related to speeding is influenced by both the risk and the consequences of being caught for violations. Correspondingly, the deterrents for speed violations can be in one of two major forms: (1) Police enforcement of speed limits (determines the risk of getting caught) and (2) Severity of the punishment for violation of speed limits (determines the consequences of getting caught). The intent of our study is to examine the simultaneous impacts of enforcement (by police officers) and increased penalties on freeway speeds and crashes using data from the Enhanced Penalty Zones (EPZs) established by the 2006 Florida Legislature on Interstate 95 in three counties in Florida. The data on enforcement activities will be collected during this study period by the Florida Highway Patrol (FHP), a matching partner in this project.
