Book Description
Before they begin their university studies, most students have experience with traffic signals, as drivers, pedestrians and bicycle riders. One of the tasks of the introductory course in transportation engineering is to portray the traffic signal control system in a way that connects with these experiences. The challenge is to reveal the system in a simple enough way to allow the student "in the door," but to include enough complexity so that this process of learning about signalized intersections is both challenging and rewarding. We have approached the process of developing this module with the following guidelines: * Focusing on the automobile user and pretimed signal operation allows the student to learn about fundamental principles of a signalized intersection, while laying the foundation for future courses that address other users (pedestrians, bicycle riders, public transit operators) and more advanced traffic control schemes such as actuated control, coordinated signal systems, and adaptive control. * Queuing models are presented as a way of learning about the fundamentals of traffic flow at a signalized intersection. A graphical approach is taken so that students can see how flow profile diagrams, cumulative vehicle diagrams, and queue accumulation polygons are powerful representations of the operation and performance of a signalized intersection. * Only those equations that students can apply with some degree of understanding are presented. For example, the uniform delay equation is developed and used as a means of representing intersection performance. However, the second and third terms of the Highway Capacity Manual delay equation are not included, as students will have no basis for understanding the foundation of these terms. * Learning objectives are clearly stated at the beginning of each section so that the student knows what is to come. At the end of each section, the learning objectives are reiterated along with a set of concepts that students should understand once they complete the work in the section. * Over 70 figures are included in the module. We believe that graphically illustrating basic concepts is an important way for students to learn, particularly for queuing model concepts and the development of the change and clearance timing intervals. * Over 50 computational problems and two field exercises are provided to give students the chance to test their understanding of the material. The sequence in which concepts are presented in this module, and the way in which more complex ideas build on the more fundamental ones, was based on our study of student learning in the introductory course. The development of each concept leads to an element in the culminating activity: the design and evaluation of a signal timing plan in section 9. For example, to complete step 1 of the design process, the student must learn about the sequencing and control of movements, presented in section 3 of this module. But to determine split times, step 6 of the design process, four concepts must be learned including flow (section 2), sequencing and control of movements (section 3), sufficiency of capacity (section 6), and cycle length and splits (section 8). Depending on the pace desired by the instructor, this material can be covered in 9 to 12 class periods.

Book Description
Highway Capacity Analysis provides students with foundational principles, concepts, and theory regarding capacity analysis to prepare them for work as an operational traffic engineer. Students learn how the mastery of capacity analysis applies to signal operations and optimization, roadway and intersection design, transportation planning, and traffic impact analysis. The text also prepares students to use the necessary software employed within the traffic engineering profession. The text is divided into three sections: Uninterrupted Flow, Interrupted Flow, and Application Extensions. In Part I, students learn how to analyze uninterrupted flow segments and facilities, including freeways and highways. Part II discusses the analysis of stop control, roundabouts, signalized intersections, urban streets, interchanges, and alternative intersections, with multimodal analysis and travel time reliability included where applicable. Part III extends the procedural analyses outlined in Parts I and II into broader applications, including signal timing optimization and traffic impact studies. Students follow step-by-step procedures to work through exercises by hand, then code them into software to experience their learnings in practice. Providing a practical, succinct, and logical approach to traffic engineering processes and procedures, Highway Capacity Analysis prepares students to enter the traffic engineering profession with the knowhow and practical experience required to succeed. The text is well suited to courses in traffic engineering and transportation.
