In long-term work zones, speed photo enforced signs can be complemented with DSDS. At the third site Route 19 the speed reductions at the middle of the work zone were about 16.

Sometimes drivers do not follow the messages on the PCMS as they doubt the reliability of the signs []. J Traffic Logist Eng 6 2 :48—52• Different display signs are used to influence driver speeding behavior in a work zone. Future studies would involve testing a combination of speed photo enforced signs along with DSDS in a work zone and validating the results by comparing them with real-world data. 8 milesconsisting of three 12-foot lanes and a reduced speed limit of 35 mph within the work zone.

If the radar detected a vehicle traveling above a preset speed threshold, the CMS displayed the message 'You are speeding slow down'. However, implementation of such interventions before proper validation can undermine rather than enhance safety and may lead to potentially fatal outcomes [].

Benekohal R, Wang M-H, Chitturi M et al 2009 Speed photo-radar enforcement and its effects on speed in work zones. Credibility is a general issue with CMSs that also applies to the application of CMSs in work zones.

The purpose of the Phase 2 study was to confirm the findings of the Phase 1 study and evaluate the effectiveness of radar equipped DMS at reducing vehicle speeds in work zones in place up to seven weeks.

Speed activated dynamic message signs (DMS) with warning messages reduced speeding vehicles by 50 percent or more in Virginia work zones.

The authors propose that speed cameras along with the proper signage be installed in high-speed work zones, especially in places like tunnels where work zone crews are most vulnerable. Transportation Research Record, 1086, 36-42.

A few simulation studies indicated that using graphic-aided PCMSs could likely overcome these limitations. The conventional practice for regulating work zone speeds has been static signing procedures using regulatory or advisory speed signs.

Uncontrolled Terms: ; ; ; ;• Statistical tests were then conducted using these speed characteristics to determine whether significant reductions in speed accompanied the use of CMS. 05, the t test is valid. When CMSs are provided to reduce driver speeds, compliance is increased when a reason for the reduced speed is displayed 1.

In another study, driver behavior was investigated through sequential PCMS []. This report is the second phase of a longitudinal research study.
