Transportation Planning

Transportation Planning is essentially the confluence many different disciplines coming together in the first stages of the development of plans, policies and legislative activities, funding, and project development. In, Designing Walkable Urban Thoroughfares: A Context Sensitive Approach, Transportation Planning is defined as "a collaborative and participatory process involving agencies, organizations and the public in a comprehensive look at national, state, regional and community needs…It examines demographic characteristics and travel patterns for a given area, shows how these characteristics will change over a given period of time and evaluates alternative improvements for the transportation system."




In the Transportation Planning Handbook, Third Edition, transportation planning practice is defined as improving coordination between land use and transportation system planning; providing cooperative interaction between planning, design, and operation of transportation services; maintaining a balance between transportation-related energy use, clean air and water, and encouraging alternative modes of transportation that will enhance efficiency while providing high levels of mobility and safety. 


Accessibility and Transportation for All Users

Roadways are not designed for one type of vehicle, and a one size fits all approach to pedestrian design does not work either. Pedestrians have varying abilities. One in every five people in this country has a disability, and one third of our population does not drive. These numbers alone reveal the diversity we have in this country and the need for a variety of transportation choices. A large segment of the disabled population cannot leave home and travel to their destination independently. Many people with disabilities have low vision or are blind. Accessibility is a paramount safety issue to individuals with vision disabilities. Roadway designs have changed over the past 30 and 40 years, and many of these changes have made the simple task of crossing the street much more difficult, for example:

  • Larger curb radii create longer crossing distances
  • Pedestrian signals may be difficult to read from longer distances
  • Curb ramps built at low grades can be difficult to detect for a person who is blind

Following tools and activities are of significance within the accessibility area of practice for transportation professionals


Traffic Impact Analysis

The first two editions of the ITE Recommended Practice on Transportation Impact Analyses (TIASD) in 1996 and 2010 focused on describing details within the traditional “bread and butter” transportation impact analysis approach commonly used throughout the USA and Canada (the 2010 recommended practice was based on a review of some 200 jurisdictions; a similar effort supported the 1996 edition). ITE is in the process of updating the Recommended Practice on Transportation Impact Analyses for Site Development and re-branding it as a Recommended Practice on Multimodal Transportation Impact Assessments (MTIA) for site development. The update is proposed to address emerging industry considerations that include both alternative approaches for public and private sector contributions to planned transportation infrastructure and services and a greater focus on multimodal measures of effectiveness.

The update is designed to address these areas as communities and practitioners alike are seeking guidance on how to evaluate the opportunities and constraints with innovative approaches to rethinking traditional TIASD approaches. The timing is therefore appropriate for a new Multimodal Transportation Impact Assessment (MTIA) Recommended Practice to update, and replace, the TIASD. The MTIA should achieve the following key objectives:

  • Broaden the understanding of TIASD strategies to help practitioners and decision makers assess the pros and cons of a variety of approaches for addressing the relationship between the approval of new development and the maintenance of transportation system performance;
  • Reflect current and emerging technologies in both measuring transportation system;
  • Promote context-sensitive solutions from policy and planning perspectives; and
  • Support strategies for implementing transportation systems across all modes



The Parking Standing Committee was formed to identify, educate and promote effective practices in the planning, design, operations and management of parking facilities. The council will focus on the following areas in the coming years: the relationship between land use and parking supply, (parking generation), parking management programs and transportation engineering issues associated with parking. The council sponsors numerous sessions at ITE’s Technical Conference and Exhibit and Annual Meeting and Exhibit. The council also assisted in developing Parking Generation Informational Report, Third Edition and helps organize new data submissions to ITE. Click here to learn more.
