      <title>State of the Practice and Recommendations on Traffic Control Strategies at Toll Plazas</title>
      <link>https://trid.trb.org/View/793270</link>
      <description><![CDATA[This report has been prepared under a project initiative by the Federal Highway Administration to identify the state-of-the-practice for traffic control strategies at toll plazas, and to develop recommended guidelines for agencies and departments that operate or plan to design and build such facilities.  The report contents begin with an introductory chapter.  This chapter includes sections that outline the purpose of this project, provide a problem statement articulating the focus of the project efforts, list the study objectives, describe the methodology used to achieve the objectives, and conclude with the intended use of this report.  The introduction is followed by four chapters that include the state-of-the-practice and recommended guidelines for the following technical areas encompassing the development of traffic control strategies at toll plazas:  Plaza Operations/Lane Configuration; Signing, Markings and Channelization; Geometric and Safety Design; and Toll Collection Equipment Technology.  The aggregation of these chapters provides useful historical information and a comprehensive analysis of when and where to apply various traffic control strategies.  The final chapter concludes the report by identifying further research needs, which require more rigorous study including field verification of performance.  This chapter also lists all of the recommended guidelines presented in the preceding chapters.  A glossary of terms, definitions and diagrams to assist the reader's understanding of the topic material follows along with Appendix A: Summary of Survey Results, Appendix B: Expert Panel Workshop Summary, and Appendix C: Literature Search.]]></description>

      <title>Using Decision Support System and Graphical User Interface to Choose Appropriate Lane Configurations at Toll Facilities</title>
      <link>https://trid.trb.org/View/803608</link>
      <description><![CDATA[This study shows that tools can be devised to assist engineers and operators make decisions concerning a network of toll roads. A decision support system (DSS) was connected to a database containing highway network hourly geometric and traffic information for one typical day. The DSS provided operators with online tools that could assist with their hour-to-hour decisions concerning toll plaza lane configurations. This pilot study could be extended, and the DSS could be connected to a real-time database to assist operators with their day-to-day decisions. Operators could plan for special scheduled events in which traffic volumes are known to surge. Engineers could design lane configurations at toll facilities that could meet traffic requirements. Engineers could also design new interchange locations and predict the effect on toll plaza segments. They could also predict the effect of adding additional lanes to busy highway segments. Highway operators could determine the effects of an incident or other unscheduled lane closing at any particular hour of the day. Furthermore, they could schedule maintenance and lane closings for construction at hours of the day in which bottlenecks are at a minimum.]]></description>

      <title>PROPOSED LEVEL-OF-SERVICE METHODOLOGY FOR TOLL PLAZAS</title>
      <link>https://trid.trb.org/View/729365</link>
      <description><![CDATA[A proposed macroscopic methodology for measuring the level of service (LOS) of toll plazas has been developed using delay as the measure of effectiveness (MOE).  On the basis of field research and data analyses, the 85th percentile of the cumulative individual vehicular delay was found to be the most comprehensive measure for evaluating the LOS at a toll plaza. Other MOEs were examined but found to be less flexible with different plaza configurations and lane payment types.  More than 55,000 individual vehicular records from three mainline toll plazas in Orlando, Florida, representing eight different plaza configurations with varied percentages of electronic toll collection (ETC) usage were used to validate the methodology. TPSIM, a toll plaza simulation model, was used to produce an additional 49 scenarios representing the three plazas with varied percentages of ETC usage and 21 additional plaza configurations.  Service time was examined to determine the level at which a driver begins to feel discomfort and inconvenience at a toll plaza.  An LOS hierarchy was established based on the conclusions of this analysis, feedback from professionals, and reference to the Highway Capacity Manual (HCM) 2000.  The 85th delay percentile graphs from each of the plaza analysis results for LOS values were also observed to be similar.]]></description>
