Two-Day Course Outline

  1. TTC as a function of roadway design and ability of drivers
  2. Human factors - "controlling" the driver, system of communication, PRT, etc.
  3. Standards and Guidelines - Source and legal authority, including:
    • Manual on Uniform Traffic Control Devices (MUTCD)
    • Green Book
    • Roadside Design Guide
    • State Specifications
  4. Fundamental Principles
  5. Applications
    • Definition of "system" and TTCZ component parts
    • TCP development considerations - work type, location and duration; capacity issues; day vs. nighttime work; constructability and size
  6. Design considerations of the component parts of the TTCZ
    • Work space and clear zone
    • Buffer space considerations - longitudinal, lateral, SSD formula, options, crashworthiness of devices
    • Transitions - types of tapers, applications, formulas, graphic explanation, multiple tapers
    • Advance Warning Area - function, sign selection (visibility vs. legibility, speed, spacing, location and placement), right vs. both sides, mounting standards, supplemental devices
    • Termination - tapers, advantages vs. disadvantages, end road work location
  7. Typical Applications
    • Definition, Drawing, and Notes
    • Selection and combining of typicals
    • Designing for specific field conditions - engineering study vs. judgement, classification, adjacent land use, geometric configuration, superelevation, nighttime, detours and diversions, pedestrians and the ADA
  8. Putting together the TCP
    • Format
    • Scale
    • Orientation
    • Approvals
    • Software applications
  9. Modifications/Adjustments to the TCP
    • Authority and Approval Process
    • Emergency vs. Enhancement Situations
    • Adjustment Considerations - traffic flow, visual observations, pedestrian violations, field reports, citizen complaints, etc.
  10. Legal Aspects
    • Legal definitions
    • The civil lawsuit process
    • Designer responsibilities - documentation on engineering judgement, discretionary power and immunities
