TE-41 Traffic Signal Design: Complete Streets Application
DescriptionThis new course introduces the practical design considerations in traffic signal designs that are above and beyond the basic introductions. Within the framework of the California Vehicle Code, the California Manual on Uniform Traffic Control Devices (CA MUTCD), and other national and state references with recommended practices and real-world illustrations, this course will explore the multi-modal design expectations from today's traffic signal designers in a complete-street environment. This course will introduce complex signal phasing diagrams, typical features of controller firmware, and configuration of signal cabinets; and signal indications/heads placement and detection layout with respect to design applications for rail crossings, emergency vehicles, bus transit, bicycles, pedestrians, and cars. Additionally, this course will introduce the design concept for bus rapid transit (BRT), light rail transit (LRT) and heavy rail. The course includes lectures, sample problems, and exercise projects that will familiarize the course participant with the design process that starts with preliminary and progress design submittals, as well as formats of design review comments and resolutions expected by typical public agencies. While this course is suitable for traffic signal designers with varying experience, this course will be introduced as a sequential next-level course to Tech Transfer's TE-02 (Traffic Signal Design: Engineering Concepts), or equivalent. The goal is for the course participants to become familiar with real-world, multi-modal, signal-design applications that accommodate various street types and intersections users.
- signal phasing (review of basics)
- complex signal phasing
- controller firmware features and signal cabinet configurations
- layout of signal heads and detections within Multi-Modal Contexts
- adaptive traffic control and other "next gen" options
- sample applications in various modes:
- pedestrians (hybrid beacons, lead pedestrian intervals and pedestrian scrambles)
- bicycles (Types I-III/IV bikeways)
- transit signal priority and bus rapid transits
- emergency vehicles (fire station and en-route), rail crossings (typical, pre-signal, queue-cutter)
- light rail transit
What You Will LearnStudents gain a good working understanding of concepts and engineering practices needed to develop plans for traffic signal installations within a multi-modal context.
Who Should AttendThis is a next-level sequential course targeted for traffic engineers, technicians, and maintenance and construction personnel with adequate traffic signal design experience or prior training equivalent to Tech Transfer's TE-02 (Traffic Signal Design: Engineering Concepts) course.
RequirementsPlease bring the following tools to the course: pocket calculator, engineer's scale (with 1:20 scale), 12" straight edge, and four colored pencils (red, green, blue, black). Optional item is a template with circles, squares and rectangles. The perspective course participants will be exposed to Caltrans Standard Plans and Specifications, and are encouraged to review them online at http://www.dot.ca.gov/hq/esc/oe/construction_standards.html
