Training & Workshops

More information about these courses, including upcoming dates, is available through the National Highway Institute.

Highway Capacity and Quality of Flow, NHI Course 133005A

A training course on the 2000 Highway Capacity Manual (HCM) is available from the National Highway Institute of Federal Highway Administration. This course provides instruction in the use of HCM.

Software is employed in most of the capacity analyses performed in the course. Approximately one-half of the course is dedicated to sessions on interrupted flow facilities (i.e., signalized intersections, unsignalized intersections and arterials). The remainder of the course covers freeways, weaving sections, ramps, multilane, and two-lane rural facilities. The course includes lectures describing the procedures for performing capacity analyses on each type of highway facility. Demonstrations and hands-on application of the highway capacity software are used to solve example and workshop problems.

Objective

Upon completion of the course, participants will be able to:

  • Explain facility characteristics and their limits as used in the HCM 2000 English.
  • Explain analytical procedures and how to apply them.
  • Use formulas by inputting data, reviewing and adjusting default values or adjusting factors, as necessary, for project and local conditions.
  • Determine LOS from results.

Target Audience

State, local, FHWA, contractors, and MPOs who design and analyze intersections, interface with freeways, deal with signal time issues, design and manage operations of urban streets, plan for type of intersections for future needs, work with system(s) monitoring and management of arterial systems; or who conduct operational analysis to determine needs of highway facility, estimate the level of service for new/proposed and existing operations, and manage freeway systems.


CORSIM Traffic Simulation Model Training, NHI Course 137022A

This course provides an understanding of CORSIM - a tool that simulates traffic and traffic control conditions on combined surface street and freeway networks. CORSIM determines how traffic engineering and control strategies impact a prescribed network's operational performance, as expressed in terms of various Measures of Effectiveness (MOEs). The MOEs (such as speed, travel time, volume, and delay) provide insights into the effects of the applied strategy on traffic operations and provide the basis for optimizing the applied strategy. CORSIM, the simulation package within the Traffic Software Integrated System (TSIS) suite of tools, is a powerful tool that can be applied to wide areas of interest including:

  1. Practical traffic engineering activities such as signal retiming, traffic impact studies, analysis of major traffic events, stadium operations, corridor traffic operations, and freeway incident impacts.
  2. Evaluating ITS technologies, such as real time traffic adaptive control, real time traveler information and route guidance, and network-wide dynamic traffic assignment.

Objective

Upon completion of the course, participants will be able to:

  • Describe CORSIM features (including advantages and disadvantages).
  • Determine appropriate uses for CORSIM.
  • Identify types and sources of data.
  • Given real-world data, prepare a link-node diagram, then code for input to CORSIM.
  • Input data, run CORSIM, and interpret output for arterial, freeway, and combined networks.
  • Identify circumstances and procedures for calibrating models.
  • Interpret and fix common error messages.
  • Use CORSIM to simulate traffic improvements.

Target Audience

Traffic engineers in the public and private sectors, as well as in academia, who are involved in ITS planning and deployment.
