The Wisconsin Department of Transportation (WisDOT) owns and operates a state highway network of 12,000 miles, which carries approximately 80 percent of vehicle miles traveled in the state. Construction, maintenance, weather and other events often lead to lane closures or restrictions, causing inconvenience to road users. WisDOT developed numerous strategies for identifying alternate routes that drivers can use when highway travel times are affected by planned or unplanned events. Despite these efforts, WisDOT has observed that many alternate routes are underused, even when those routes would save travelers significant travel time. The objective of this project was to examine the decision-making processes of Wisconsin drivers regarding route selection, including their decisions to use (or not use) an alternate route instead of the highway network. Factors that were examined included how and when drivers make initial decisions about a preferred route, for both familiar and unfamiliar trips; the factors that influence their decisions to divert or not divert from their usual (or current) route to an alternate route; and the information sources they would most likely consult for travel and route information.

This research used a fixed-base driving simulator to determine the effects of dynamic message signs (DMSs) on driver behavior. A DMS notifies drivers with safety, weather, incident, or traffic condition messages. Recently, however, state Departments of Transportation (DOTs) display safety messages with entertaining content. The Kansas DOT (KDOT) wanted to assess how these entertaining messages affect driving behavior. Therefore, this research evaluated the effect of DMS content on driver behavior using a combination of surveys and driver behavior data obtained from a fixed-base driving simulator. Existing literature was reviewed to determine similar studies. Based on the literature, which included results of DMS modeling in driving simulators and DMS effects on driver behavior, a research methodology was developed. One hundred participants were recruited and screened using an online survey questionnaire that included messages currently displayed on DMS; feedback on their perceived effectiveness was requested. The second data collection was done via a driving simulator experiment. The simulator was prepared for the study, the DMS was set, and events were designed to capture changes in driver behavior and awareness. A total of 60 participants with diverse demographics drove by several DMSs that displayed a variety of messages. Participants completed a survey at the end of the experiment, and their responses were compared to responses of the online survey. Behavioral data (speeds, accelerations, gazes, etc.) were then reduced, and statistical analyses were performed, including hypothesis testing and analysis of variance, to evaluate to what extent the message content affected driver behavior. The study identified potential messages that were found to effectively affect driver behavior.

Intelligent Transportation Systems: Functional Design for Economical and Efficient Traffic Management provides practical guidance on the efficient use of resources in the design of ITS. The author explains how functional design alternatives can meet project objectives and requirements with optimal cost effectiveness and clarifies how transportation planning and traffic diversion principles relate to functional ITS device selections and equipment locations. Methodologies for translating objectives to functional device types, determining device deployment densities and determining the best placement of CCTV cameras and message signs are provided, as are models for evaluating the benefits of design alternatives based on traffic conditions. Readers will learn how to reduce recurrent congestion, improve incident clearance time in non-recurrent congestion, provide real-time incident information to motorists, and leverage transportation management center data for lane control through important new active transportation and demand management (ATDM) methods. Finally, the author examines exciting developments in connected vehicle technologies, exploring their potential to greatly improve safety, mobility and energy efficiency. This resource will greatly benefit all ITS designers and managers and is of pivotal importance for operating agencies performing evaluations to justify operational funding and system expansions.

Further research into how the warning message is presented or worded could provide additional insight into the impact it can have on driver behavior. Since it is observed that drivers acknowledge the 'reduce speed' advisement, it is likely that specifying a specific speed limit could also warrant driver obedience. Additional testing and observation of driver reaction to larger traffic volumes and situations within the fog would also allow for further analysis of driver behavior under reduced visibility and the impact the early warning system has on their behavior.

"This research project examined the effects of sequential Portable Changeable Message Signs (PCMS) on driver behavior in work zones. PCMS are temporary traffic control (TTC) devices, part of Intelligent Transportation Systems, which supplement static signs to provide advance warning and real-time information to drivers. Text and number based messages are displayed on the PCMS for which detailed evaluation has not been carried out before. This research fills this gap using a driving simulator (DS) supplemented by objective and subjective surveys. A work zone on I-44 in rural Missouri was replicated in the DS using video recordings and GIS (Geographical Information System) data. The DS experiment consisted of five scenarios (0-4). The control scenario (scenario-0) was compared to scenarios 1-4. In the DS, evaluation of the four message signs displayed on the PCMS used by the Missouri Department of Transportation (MoDOT) and their effects on drivers' speed was carried out. The results from the experiment showed significant decrease in speed of driver as a result of the type of messages displayed by the PCMS. From the objective analysis results, message sign-4 (MS-4) saw the maximum decrease in the speeds of drivers when compared to the control scenario. The subjective (survey) results showed that MS-2 was the most preferred message as it displayed a specific speed limit for the participants to follow. Also, the 85th percentile speeds before the construction zone closely matched with the displayed speed for MS-2. The results obtained from the subjective survey reinforced the fact that PCMS were effective in reducing the speed of the drivers"--Abstract, leaf iii.
