What Are They? Strategies intended to offset vehicle-trip impacts associated with new development Developers can be incentivized or mandated to implement these strategies Incentives and mandates can apply to subsequent property owners Incentives and mandates should be proportional to vehicle impacts TDM programs and infrastructure should be applicable to available transportation options and land uses
3
What are the Benefits? Reduce need for roadway investmentsReduce parking requirementsMaximize ROI from existing infrastructureImprove community healthProduce cost savings for travellersEfficient land useAmenity to new residents or employers

Best Practices Selection Process Multi- Jurisdictional Varied Geographies All Climates
5
Best Practices Selection Process Fairfax County, VirginiaCambridge, MassachusettsVancouver, British ColumbiaMontgomery County, MarylandYork Region, OntarioTDM in Action in Atlanta, Georgia
6
Fairfax County, Virginia Developer TDM requirements outlined County Comprehensive Plan: Large scale developments near transit stations are required to reduce vehicle trips (measured against trip generation projections) Strategies negotiated through the proffer development process.
7
Fairfax County, Virginia Developers must conduct regular vehicle trip counts and/or travel surveys to determine trip reduction targets are in compliance Proffers are legally binding and funds are deposited into both a remedy and a penalty fund. Current and future property owners are held to TDM requirements outlined in the proffers
8
Cambridge, Massachusetts Mandatory Parking and Transportation Demand Management Ordinance Adding 5 to 19 non residential parking spaces triggers TDM programming 20 or more spaces triggers a 10% trip reduction requirement below 1990 census levels & TDM plan
9
Vancouver, British Columbia New developments required to conduct a Transportation Assessment and Management Study (TAMS), which includes TDM, parking, and traffic impact City Engineering and Planning Department reviews project applications/TAMS to assure sustainable transportation options have priority over SOV use and parking
10
Montgomery County, MD Friendship Heights Downtown Bethesda Downtown Silver Spring North Bethesda Greater Shady Grove Created five transportation management districts (TMDs) through a legislative act where both existing and new developers and employers are required to implement TDM measures Typically measures are implemented through TMA’s, funded in part by TMD fees charges (set by County Council) to property owners
11
York Region, Ontario TDM is integrated into the site plan and subdivision approval process Region staff and developers negotiate what TDM action as will be taken based on anticipated traffic impacts In June 2012 the Region initiated a TDM tax on all new developments
12
Lessons Learned Development community’s involvement in policy creation and implementation is critical to success Have a well formed plan before implementation and be willing to make changes; create a checklist for developers Carrots are helpful; one size may not fit all Requirements over time should be fair, equal, consistent and possible to track Couple land use and transportation infrastructure to support trip reduction requirements
13
TDM in Action – Atlantic Station High-density infill development with a mix of uses Required special approval from the U.S. Environmental Protection Agency Robust TDM program Shuttles Commuter Café Outreach Incentives
14
Program Results– Atlantic Station New tax revenue Daily VMT per resident is 9.2 miles Average in Greater Atlanta is 27.9 miles Percentage of trips made to, from and on the site via non-SOV modes is 53%
