Title: Highway Capacity Manual 2000


1
Highway Traffic and Safety Analyses
Lecture 9 Highway Capacity Manual 2000 (original
presentation by R. Dowling revised and expanded
by A. Tarko)
Purdue University School of Civil
Engineering West Lafayette
2
Lecture Objectives
  • To highlight the content of the Year 2000 edition
    of the Highway Capacity Manual.
  • To help identify suitable procedures in the
    Manual things and properly apply to traffic
    operations problems.

3
Purpose of the HCM
  • To provide transportation practitioners and
    researchers with a consistent system of
    techniques for the evaluation of the quality of
    service on highway and street facilities.
  • HCM does not set policies regarding a desirable
    or appropriate quality of service…

4
HCM 2000 Formats
  • Book
  • Five parts, 35 chapters
  • CD-ROM
  • Book
  • Audio-visual tutorials
  • CD-ROM presentation

HCM 2000 Table of Contents
  • Part I - Overview
  • Part II - Concepts
  • Part III - Methodologies
  • Part IV - Corridor and Areawide Analyses
  • Part V - Simulation and Other Models

6
Part II. Concepts
  • Describes factors affecting LOS.
  • Identifies required input.
  • Suggests default values for input.
  • Provides service volume tables

HCM Components and Structure
  • Chapter 9 is Your Gateway to the HCM
  • Exhibit 9-1 lists facility types and components.
  • The same exhibit gives Part II and Part III
    chapter references for each facility type.
  • Chapter 9 Provides Guidance on
  • Use of defaults.
  • Use of or development of service volume tables.
  • Precision and accuracy of results.

Part III. Methodologies
  • Provides Methodologies to Compute
  • Level of Service, Delay, Queues
  • Contents
  • Freeway Facilities (4 chapters)
  • Urban Streets (3 chapters)
  • Highways (2 chapters)
  • Pedestrian Bikeways (1 chapter)
  • Transit (1 chapter)

18
Part IV. Corridor/Areawide
  • Purpose
  • How to adapt HCM to planning models
  • Multi-Modal Corridor Analysis
  • Computation of intensity, duration, extent of
    congestion (for performance measures)
  • Areawide Analysis
  • Capacity analysis for planning models
  • Speed-flow and node delay equations for models

19
Part V. Simulation
  • Purpose
  • Guidance on the use of simulation for conditions
    beyond the bounds of Part III.
  • Contents
  • Chapter 31. Simulation and Other Models
  • Introduction to simulation techniques

20
Using the HCM 2000
  • Determine Facility Type
  • See Exhibit 9-1, Chapter 5 Definitions
  • Exhibit 29-2 provides summary.
  • Review Concepts, Inputs, Defaults
  • Review relevant Part II chapter.
  • Conduct Analysis
  • Apply relevant Part III chapter.
  • Interpretation of Results
  • See Chapter 9 discussion on precision.
  • See end of Part III Chapter for sensitivity
    discussion
