DOWNLOAD EBOOKThis Dynamic Message Sign Message Design and Display Manual was written for use by Texas Department of Transportation (TxDOT) personnel who have responsibility for the operation of and/or message design for large permanent dynamic message signs (DMSs) or portable DMSs. The Manual is designed to help both new and experienced users of DMSs at various levels of the agency including 1) entry-level personnel, 2) personnel very experienced with traffic operations, and 3) managers. It provides very specific information for entry-level personnel, reminders for experienced personnel, and higher-level information for managers regardless of whether they work in one of the Traffic Management Centers (TMCs) in the state.

DOWNLOAD EBOOK"The objective of this research was to undertake a comprehensive and systematic examination of the way agencies should be organized to successfully execute operations programs that improve travel time reliability. The following types of questions were examined at the outset of this research: How does operations fit into a transportation agency's overall program? What changes can be made in agency culture and training to promote operations? Which local and regional public agencies and private-sector organizations are essential to the various aspects of operations? Are there emerging technologies, systems, or organizational structures that can be used to advance intra-agency and interagency communications and therefore operations? The research addressed a large number of topics concerning organizational and institutional approaches that could enhance highway operations and travel time reliability. The most fruitful investigation was identification of the Capability Maturity Model, used extensively in the information technology field for organizational self-assessment and continuous improvement of quality and reliability. The researchers recognized that a version of the Capability Maturity Model could be developed and applied to highway operations and in turn travel time reliability. Elements defining different levels of maturity include culture/leadership, organization and staffing, resource allocation, and partnerships."--Publisher's description.

DOWNLOAD EBOOKA comprehensive research effort to develop operator's manuals for variable message signs (VMSs) was undertaken to improve the operations of both portable and permanent (fixed-site) VMSs in Virginia. This report describes the development of two manuals, the Permanent VMS Operator's Manual and the Portable VMS Operator's Manual which will be published separately. These manuals were based on information obtained from the literature, VMS operators, and motorists. Issues addressed by the manuals include when a VMS should be used, where a portable VMS should be placed, and the design of the VMS message. The manuals are not simply a list of pre-defined messages. They are a series of concise modules guiding the operator through the thought process required to use a VMS effectively. The operator follows a logical decision tree from module to module, to achieve the best placement and best message for a VMS. Effective VMS use actually requires a complex thought process, despite the apparent simplicity of the messages. The manuals include essential material about VMS operation. Based on theoretical calculations and motorists' experiences, it is strongly recommended that a VMS use no more than two message screens. A single message screen is preferred. VMSs should be used only to advise drivers of changed traffic conditions and convey specific traffic information concisely. Due to limited information capabilities, VMSs should be used in conjunction with other means of communication such as highway advisory radio and static signs. Most importantly, it is crucial that credibility be maintained. Incorrect information can have extreme consequences in terms of VMS effectiveness.

DOWNLOAD EBOOKThe objective of this research project was to determine appropriate guidelines and methodology for evaluating dynamic message sign (DMS) performance. National literature reviews and agency surveys were conducted and synthesized for a critical assessment of the state-of-the practice in DMS performance evaluation. DMS performance metrics were established based upon data availability, time of evaluation (pre-post)), and environment of application (urban/rural). Both qualitative and quantitative DMS benefits were established with examples of associated analysis tools given and discussed. Case studies were conducted along freeway corridors where DMSs had been implemented in both urban (Houston, Texas) and rural (Amarillo, Texas) environments. The results of these case studies highlighted constraints in both data availability and appropriate analysis procedures. Final guidelines and methodology for DMS performance evaluation were produced emphasizing the limitation to assessment of both qualitative and quantitative benefits. A guidebook of DMS performance evaluation procedures was included as Appendix D in the research report.

DOWNLOAD EBOOKIt has been perceived that the travelers do not respond to the incident messages on the dynamic message signs in the Las Vegas area in Nevada. The objective of the study is to evaluate whether dynamic message signs (DMS) in the Las Vegas freeway systems have been effective in distributing incident/traffic information. Specifically, this study investigates whether incident/traffic information can be distributed to the motorists in a timely manner: at the right time and at right location and in the right format. A literature review is conducted to see how dynamic message signs have been used effectively in other cities in the U.S. A tour to the traffic management center, the Freeway and Arterial System of Transportation (FAST) is made to observe the operations of DMSs. The performance of DMSs in providing traffic information to allow travelers to take alternative route is evaluated based on comparing the congestion progression and the activation of DMSs. A survey to travelers in the Las Vegas area is also conducted. Based on the investigations, it is concluded that (1) incident information should be provided earlier; (2) more relevant information on incident should be provided; and (3) more reliable information should be provided. Based on the conclusions, it is recommended (1) developing a computer aid system for using dynamic message signs in traffic management, (2) improving on the messages on incidents provided on DMS, (3) improving the reliability of travel time information provided on DMS, (4) improving the data system in incident management in FAST, and (5) conducting a study on locating the DMSs on the Las Vegas network.
