“…This study investigated the effects of three mobile work zone barriers on drivers' throttle/brake control behavior (speeding behavior) and steering handling behavior (vehicle's lateral movement) on an arterial road using a driving simulator. When compared to cone pylons, the mean vehicle speeds were higher while driving beside concrete barriers, which corresponds with prior research [13], [14]. In this study, participants' age and gender did not have any effect on driving behavior while driving beside mobile work zone barriers.…”

“…This could be attributed to the driver's growing impatience over time or growing comfort and familiarity with the work zone. Average speed was higher beside concrete jersey barriers compared to drums which was consistent with the results obtained by Reyes and Khan [14]. Reyes and Khan [14] showed that the participants in the study drove the fastest and with less variability in work zones with concrete jersey barriers.…”

In the year 2015, in the United States, a work zone crash occurred once every 5.4 minutes, according to the Federal Highway Administration (FHWA). Work zone barriers can help reduce the risk to the work crew as well as drivers by containing and redirecting vehicles, thereby minimizing the risk of vehicles entering work zones. In a first of a kind study on an arterial road, this study investigated the impact of work zone barriers (cone pylons, concrete jersey barriers, and metal barriers) on driver behavior; speeding and lateral movement, using a high fidelity driving simulator. Traffic volumes were based on Level of Service (LOS) C in which 53 individuals participated in the study. Analysis of variance (ANOVA) test indicated that there was a statistically significant difference between mean vehicle speeds and mean vehicle deviation from the lane center while driving beside cone pylons, concrete jersey barriers, and metal barriers. An additional Tukey's Post Hoc analysis disclosed that the difference in means is statistically significant only between cone pylons and concrete jersey barriers. The study results indicated that drivers tend to increase speed alongside concrete jersey barriers, which corresponds with prior research. An interesting observation was that drivers tend to deviate from the center of the lane, away from the barrier, while driving alongside concrete jersey barriers. 

“…These numbers can be reduced by innovations in work zone signage. However, implementation of such interventions before proper validation can undermine rather than enhance safety and may lead to potentially fatal outcomes [4].…”

“…Results from this study can be used by safety experts to deploy the most effective signage to compel drivers to slow down in a work zone, thereby safeguarding both the driver and the work zone crews. For enhanced traffic safety, studying driver behavior is fundamentally significant [4]. Diverse factors impact the speed of vehicles traveling through a work zone, such as road geometry, warning signs and traffic control devices, speed displays and law enforcement [10].…”

Speeding in a work zone needs to be tackled effectively to enhance work zone safety. This study evaluates the influence of three different work zone signsspeed photo enforced signs, dynamic speed display signs and reduced speed limit signs-on driver speeding behavior using a medium-fidelity driving simulator. The speed photo enforced and reduced speed limit signs were placed at intervals before the start of the work zone and in the work zone. A virtual work zone network was built to replicate the Baltimore-Washington Parkway (MD-295). A total of 66 participants from different socioeconomic backgrounds participated in 264 driving simulation sessions. The speeds were measured over four phases: initial speed area, sign visible area, sign readable area and post sign area. An analysis of variance and post hoc analysis showed that the speed photo enforced sign was the most effective of the three signs. The second speed photo enforced sign within the work zone was more effective at reducing speed than the sign before the start of the work zone, especially in the post sign area. It was observed that female participants tend to slow down more when encountering a speed photo enforcement sign.

A simulator-based approach for modeling longitudinal driving behavior in construction work zones: Exploration and assessment

The essential need to maintain roadway structures makes encountering work zones an inevitable part of today’s driving. The corresponding changes in traffic dynamics directly affect the drivers’ mobility and safety. Accordingly, a closer look into driver’s interaction with work zones’ geometrics and activity features may be helpful. The overall objective of this study is to examine the longitudinal characteristics of driver behavior in different work zone conditions. Based on existing literature, the variables defining these work zone conditions were specified as the work zone length, the barrier type and the level of activity. Eight different scenarios were designed by changing these three variables in a driving simulator and 40 trajectory data sets were recorded. Using a genetic algorithm, these data sets were used to calibrate a prospect theory-based acceleration model. The calibrated parameter values helped quantify the driver’s perception of the surrounding environment, his/her risk-attitudes and the corresponding judgment process.
