“…Over the past couple of decades, numerous attempts have been made by researchers to understand the influence of various design, traffic, and environmental factors on driving behavior [1][2][3][4][5][6][7]. Efforts have also been made to develop accurate model(s) of drivers' behavioral response(s) to these factors [8][9][10][11][12].…”

This study investigates the potential effect(s) of different dynamic message signs (DMSs) on driver behavior using a full-scale high-fidelity driving simulator. Different DMSs are categorized by their content, structure, and type of messages. A random forest algorithm is used for three separate behavioral analyses—a route diversion analysis, a route choice analysis, and a compliance analysis—to identify the potential and relative influences of different DMSs on these aspects of driver behavior. A total of 390 simulation runs are conducted using a sample of 65 participants from diverse socioeconomic backgrounds. Results obtained suggest that DMSs displaying lane closure and delay information with advisory messages are most influential with regards to diversion, while color-coded DMSs and DMSs with avoid route advice are the top contributors potentially impacting route choice decisions and DMS compliance. In this first-of-a-kind study, based on the responses to the pre- and post-simulation surveys as well as results obtained from the analysis of driving-simulation-session data, the authors found that color-coded DMSs are more effective than alphanumeric DMSs, especially in scenarios that demand high compliance from drivers. The increased effectiveness may be attributed to reduced comprehension time and ease with which such DMSs are understood by a greater percentage of road users.

“…This study, in a first of its kind, investigates the influence of units of information on a DMS display on driver speeding behavior. Nowadays, researchers have been using the evolving driving simulator (DS) technology to investigate driver behavior under various conditions [4,6,8,10,11,[21][22][23][24][25][26][27] and as such, this study uses a medium-fidelity driving simulator to conduct this speed study.…”

A single unit of information is an answer to any anticipated question a motorist may ask. Such questions include: "What happened? Where? What do I do?" This study, a first of its kind, analyzes the optimum number of units of information Dynamic Message Signs (DMSs) should display to influence driver speeding behavior. A 155-mi 2 virtual road network of the Baltimore-Washington Parkway (MD-295) in Maryland was developed for use with a mediumfidelity driving simulator, and 65 participants took part in the study. Six scenarios featured DMSs displaying 2-7 units of information, interchangeably, and a total of 296 simulation sessions were conducted. Mean speeds are calculated over five different phases: the initial speed area, visible area, readable area, lost legibility area and post DMS area. Analysis of variance (ANOVA) and post-hoc analysis showed that participants tend to accelerate as soon as they lose sight of the DMS displaying 2-3 units of information and continue to do so after they pass the DMS. An ordinary least squares (OLS) regression analysis reveals that participants older than 55 slow down the most when they encounter DMSs with 6-7 units of information. Participants in the age group of 26-35 tend to increase speeds, especially when a DMS displays 2-4 units of information. This suggests that the comprehension time is low when there are fewer units of information on a DMS. Too little information may be unclear or ambiguous whereas too much may be hard to comprehend and cause drivers to slow down.

“…Numerous studies have been conducted to evaluate driver behavior under various circumstances using a driving simulator [24][25][26][27][28][29][30][31]. Some studies investigated the impact of work zone barriers (cone pylons, concrete jersey barriers and metal barriers) on driver behavior [24], while some analyze drivers' behavior under different climatic conditions like foggy conditions and reduced visibility [25,29,30]. Most of the simulator studies investigated the impact of different kind of message signs on driver's route choice and compliance behavior, diversion of traffic, speed patterns, sign effectiveness and safety of traffic [20,[26][27][28][29]31].…”

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.
