Transportation Demand Management (TDM) is typically employer-based trip reduction programs aimed at reducing the number of vehicles (or work trips) during an average weekday. TDM programs require employers who have over a certain number of employees to promote ridesharing, transit use, telecommuting, walking or bicycling to work to help reduce work related traffic on City roads.

TDM programs need to be enforced by the lead agency (in this case, the City of Oceanside). Enforcement of such trip reduction programs to employers requires that the City either adopt an Ordinance and/or to create incentives that make TDM programs economically viable to businesses. In the past, TDM programs have not been very successful due to the ongoing monitoring and level of enforcement necessary to keep businesses in compliance. How a TDM program in the City of Oceanside will be implemented has yet to be determined.
