Transportation Demand Management (TDM) refers to programs and strategies that manage and reduce traffic congestion by encouraging the use of transportation alternatives. SANDAG coordinates a number of programs that are increasing the number of commuters who carpool, vanpool, take transit, bike, walk, and telework. These activities are facilitated through the iCommute program.
The goal of iCommute is to manage and reduce traffic congestion, as well as reduce greenhouse gas emissions and other environmental pollutants that result from commuters driving alone each day. Managing the demand for our roadways is a cost-effective method for improving the daily commute while also improving the quality of life across the region.
SANDAG works closely with Caltrans, the Metropolitan Transit System, North County Transit District, and all 19 jurisdictions within the region. Programs and services provided by iCommute include free, online ridematching, a vanpool subsidy program, transit solutions, bicycle encouragement programs, the Guaranteed Ride Home program, SchoolPool, and support for teleworking.
Public outreach increases awareness about the variety of transportation choices through events such as Bike to Work Day. Rideshare Week, Dump the Pump, and through direct outreach to employers, community groups, schools, and agencies. Information on these programs and more can be found at 511sd.com/iCommute or by calling 511 and saying “iCommute.'
Recent TDM Planning Studies
Integrating TDM Into the Planning and Development Process – A Reference For Cities
This study assists municipal governments with implementing and monitoring TDM policies as part of their local plans and projects. Information on how TDM can be effectively incorporated into urban design, site development, and parking strategies is included. Featured case studies and recommendations can be tailored to any jurisdiction’s needs. The study was accepted by the Transportation Committee on May 18, 2012, for inclusion as a resource in the SANDAG Smart Growth Toolbox.

North Coast Corridor TDM Plan
The North Coast Corridor (NCC) presents an ideal opportunity to develop and deploy a corridor-specific TDM strategy that will mitigate the construction impacts of the proposed highway improvements while directly supporting the investment in Express Lanes and rail. The plan provides context-specific TDM solutions to manage congestion during construction and act as a foundation for sustained travel behavior change once construction is complete. Plan development includes a comprehensive market research and outreach effort that revealed existing travel behavior, attitudes towards transportation alternatives, and the perceived and real barriers to using transportation alternatives. Based on the research findings and the input provided by corridor stakeholders, TDM strategies and a targeted marketing and outreach plan are being developed to meet the specific needs of NCC employers, residents, schools, agencies and institutions.

Regional Telework Demonstration Project
Telework is one of the TDM strategies identified in the 2050 Regional Transportation Plan and Sustainable Communities Strategy. The purpose of this project is to work with the business community to understand the barriers to implementing telework policies, and to develop a regional strategy for significantly expanding telework to meet our regional goal for reducing greenhouse gas emissions. An extensive research effort that included focus groups, surveys and interviews with a range of employers is complete and will inform the development of a Regional Telework Strategy to be piloted with select employers in the region in late 2013.
