The purpose of transportation demand management (TDM) requirements is to encourage large employers to implement programs and make site improvements that will help reduce the number of single-occupancy vehicle commuters on the roads. Large numbers of commuters have many negative impacts on the community such as increased traffic congestion, reduced worker productivity, and air quality and other environmental impacts. TDM strategies include, but are not limited to, employer-provided transit passes/parking credits, low-speed communications infrastructure for telecommuting, and carpooling incentives. TDM requirements apply to all new office, commercial, mixed use, or industrial developments.
