CMP Technical Guidelines
Transportation Impact Analysis (TIA) Guidelines
The TIA Guidelines document (last updated October 2014) presents VTA's guidelines for preparing Transportation Impact Analyses (TIAs). TIAs are prepared to assess the transportation impacts of land development projects and to assist in identifying whether improvements are needed to the roadways, bike routes, sidewalks, and transit services affected by the project.
Traffic Level of Service (LOS) Analysis Guidelines
The LOS Analysis Guidelines document (last updated June 2003) presents analysis methodologies that must be used to evaluate LOS on CMP roadway facilities within Santa Clara County.
Local Model Consistency Guidelines
The Local Model Consistency Guidelines document (last updated May 2009) describes the process the local agencies should consider in order to develop models consistent with the VTA Countywide models, and the steps that will be required to certify model consistency.
Deficiency Plan Requirements
Deficiency plans, as it relates to traffic congestion management, are plans that identify offsetting measures to improve transportation conditions on the Congestion Management Program (CMP) facility in lieu of making physical traffic capacity improvements such as widening an intersection or roadway. The purpose of this document is to provide Member Agencies with specific details on deficiency plan preparations, content requirements, approval process, monitoring, and responsibilities.
The VTA Deficiency Plan Requirements (last updated September 2010) is an update to the existing “Requirements for Deficiency Plans” document adopted on November 18, 1992. The VTA Deficiency Plan Requirements document has been simplified and updated to focus on providing instructions on developing deficiency plans, to reflect current practices, policies, and procedures that were not yet established when the existing document was developed, and to be consistent with the recently updated VTA Transportation Impact Analysis (TIA) Guidelines.
