Purpose of the P <br />an <br />The Tukwila Transportation Demand Management (TDM) Plan provides guidance for the City's TDM <br />Program and our partners to enhance and expand transportation access for everyone who lives, works, <br />or spends time in Tukwila. The Tukwila TDM Plan: <br />• Provides background information on the Program for future implementers <br />• Outlines the current focus of the Tukwila TDM Program <br />• Suggests strategies for enhancing the Tukwila TDM Program in the future <br />Why coes Tu<wi a neer a IDM P an? <br />Tukwila is one of many Puget Sound jurisdictions experiencing rapid and sustained growth. As the <br />transportation networks in Tukwila and the Puget Sound region strain to keep up with demand, TDM <br />offers an alternative approach to help people travel around the region without widening roads. This <br />method has many positive externalities beyond improving the efficiency of transportation systems and <br />saving capital funds, including improved quality of life, public health benefits, and reduced greenhouse <br />gas (GHG) emissions. <br />Benefits of TDM <br />TDM offers supplemental transportation management strategies that can positively impact all of the <br />following objectives,2 often without modifying the transportation network or provision of services: <br />• Congestion Reduction <br />• Road & Parking Savings <br />• Consumer Savings (vehicle and fuel costs) <br />• Transportation Mode Choice <br />• Road Safety <br />• Environmental Protection <br />• Efficient Land Use <br />• Community Livability <br />Regulatory or infrastructure expansion strategies to manage demand often do not meet all of these <br />objectives, and indeed may be counterproductive. For example, widening roads does not positively <br />affect any of the objectives listed above other than congestion reduction, which is often short-lived'. <br />The degree to which these objectives are supported by TDM programs is determined by which TDM <br />strategies are implemented in a given area or community. Potential strategies include: <br />• Improve the transportation options available to consumers <br />• Educate and provide incentives use alternative modes and reduce drive -alone travel <br />• Expand/improve bicycling and pedestrian infrastructure <br />• Support strategic land use objectives (create compact, connected urban neighborhoods) <br />• Reduce the need for travel through transportation substitutes (e.g. flex schedule, telework) <br />2 TDM Encyclopedia, Impact Evaluation Table https://www.vtpi.org/tdm/tdm5l.htm accessed June 6, 2017 <br />3 Generated Traffic and Induced Travel: Implications for Transport Planning Victoria Transport Policy Institute, April <br />20, 2017 <br />4 <br />
