The Transportation Safety Planning Working Group (TSPWG), formerly known as the Safety Conscious Planning Working Group, is an informal, ad hoc partnership of U.S. DOT agencies (Federal Highway Administration, Federal Transit Administration, Federal Motor Carrier Safety Administration, and the National Highway Traffic Safety Administration) and professional associations representing state DOT, safety, traffic engineering and planning communities. The Transportation Research Board convenes and moderates the TSPWG, and hosts the web site.

The group began in May 2000 to identify strategies for moving forward on the integration of safety into the long range transportation planning process to reduce the number and severity of crashes on the nation's roadways. Since that time, TSPWG has also added advocacy for the development and implementation of Strategic Highway Safety Plans (SHSP) as required by SAFETEA-LU to its plate. It meets every 2-3 months to develop ideas, foster and encourage activities, gather and exchange information, review developments in the transportation safety planning field and to identify opportunities for additional outreach to transportation planners along with tools to assist them with safety integration.

The original purpose of the group was to brainstorm ideas on how to accomplish safety conscious planning. After the first brainstorming session, a limited number of the suggested activities were selected for further pursuit. These included providing a forum for the exchange of information (now known as Safety Conscious Planning forums) and developing a model workshop on safety planning.

To encompass the SHSP, Safety Conscious Planning, and safety integration, a new term was adopted – Transportation Safety Planning. It more accurately reflects the broader role of safety and the relationship between the transportation planning process and the state SHSP.
