TE-42 Multimodal Transportation Impact Analysis
Check for other dates/locations
This course grants 1.6 CEUs and 16.0 AICP CMs. (AICP CMs pending approval)
Recent California legislation, as well as public sentiment, has made it imperative that transportation professionals better understand how to analyze and interpret performance measures related to complete streets and sustainable transportation. This new course provides the basics and practical applications for determining level of service for pedestrians, bicyclists, bus transit users, and auto users. It also provides information on the evolving changes in CEQA (SB 743- Steinberg) that requires determining the vehicle miles of travel (VMT) generated by proposed land development and transportation projects, and the determination of what constitutes a significant impact under the new law (including safety impacts).
The course emphasizes the use of the latest Highway Capacity Manual 6th edition (HCM6, released in 2016), the Institute of Transportation Engineer's (ITE) new Trip Generation Handbook 3rd edition, and other methods, and the latest state rules.
This course focuses on urban/suburban streets (non-freeways), with equal emphasis on responsibilities normally under Caltrans' or local agency control. Applications of analyses include improving transportation project design, preparation of defensible environmental impact reports and project mitigation, and prioritizing facilities for improvement.
This course combines instructor presentations with interactive engagements to apply the techniques in the real-world, with case studies and applications of the material.
Attendees will also become familiar with:

- Cross-modal impacts (when capacity or physical characteristics of one mode are changed and thereby affect another mode using the street)
- Labor-saving shortcuts for data collection (because some multi-modal level of service methodologies can be very "data hungry")
- How 'induced travel demand' is defined, and when it does (or does not) create a significant environmental impact under the law
- Determining what causes a potentially significant safety impact
- the Level of Service (LOS) concept-- what it means and why do it, pros and cons of different methods
- research behind the newest HCM, released late in 2016
- cross-modal impacts
- how to calculate VMT from a proposed project
- gathering field information & data collection shortcuts
- software available to assist in analysis
- California statutory requirements (especially CEQA and SB 743)
- relationship to the latest Caltrans Highway Design Manual
- applications to Context Sensitive Design
- assessing safety impacts of projects
- relationship to Sustainable Transportation Indicators
- incorporation as part of project mitigation
- developing target LOS and thresholds of significance
- typical schedule and budgetary requirements
- measuring environmental justice impact
- increasing transit as a share of regional VMT
- applying analytical and simulation tools to multi-modal impact analysis
What You Will Learn
Students will learn basic level-of-service (LOS) concepts for all modes, and how to apply them to conduct performance and level-of-service analysis for various types of urban streets with various levels of accommodation for different modes; determine the impacts of system improvements using vehicle miles traveled (VMT); and analyze operational impacts of possible changes in the allocation of street cross-section to various modes.
Who Should Attend
Planners, engineers, technicians, and others at all levels of experience, including those who have had minimal prior experience with the HCM can benefit from this class, although some familiarity with the HCM is desirable. A minimal level of mathematics is required (basic algebra).
Participants will need a basic calculator for several in-class problem sets. A complete set of Course Notes (i.e., printed overhead slides) will be provided by the instructors.
Suggested Pre-Course Reading Assignments
All training participants should familiarize themselves, if possible, with the following important documents before the class to prepare themselves adequately for this focused training (at least by quickly reviewing them):
