Abstract
=========
In 2008 the City of Moreno Valley was awarded a contract to develop a TRANSIMS traffic model of the Southern California region based on the current (2004) MPO's TransCAD travel-demand model, and research certain problem statements that had been proposed by the City. This paper will present a status update of the project through model validation and peer review, as well as future steps. The following items will be included:
  • Conversion of an existing travel demand model to TRANSIMS format
  • Proposed approach to analysis of the research questions which include:
  • Analysis of the impacts of converting the zoning of 4,700 acres of undeveloped land from a mixture of land uses to high-cube warehousing, including specifically:
  • What link and intersection improvements are required to accommodate the proposed zoning changes, while maintaining a given level of service standard?
  • Will the additional truck traffic associated with the proposed zoning changes result in the need to increase the Traffic Index (and resulting structural cross-sections) of the impacted arterials and streets?
  • Will commute patterns be altered so significantly as to require major geometric changes to planned interchange improvements?
  • To what extent would the City's existing and proposed future industrial areas (which would be separated by approximately five miles of city streets) interact, and absent mitigation, how would trucks route themselves? Would these trucks impact existing or future non-industrial land uses in between?
  • Recommended measures of effectiveness for use with TRANSIMS (i.e. going above and beyond forecast daily link volumes as a measure of network performance)
  • Potential for future creation of an activity-based model
