Project Objective:
Caltrans District 7 (Los Angeles and Ventura Counties) faces a number of open research questions associated with its network modeling activities.Some of these questions are standard in the transportation planning field, and some are specific to the work done in District 7.The Office of Advance planning hopes to collaborate with USC with respect to at least two questions.
First, the Office of Advance Planning would like technical assistance to support District 7's ever expanding modeling responsibilities.This would consist primarily of a technical audit of current practices and some District work products.This review of modeling procedures would involve replication and checking of some model outputs, would result in recommendations concerning workflow, work products, and the purposes to which these products are applied.
The second question is more challenging, and has a stronger interagency component.How should regional land use and transportation be modeled?The feedback between land use and transportation is widely acknowledged, but very difficult to represent.However, there are compelling incentives to try model land use/transportation interactions.Both the Caltrans Office of Advance Planning and the SCAG Planning Data and Forecasting Section are in favor of introducing land use/transportation and level-of-service feedbacks into the standard four-step transportation model, but neither is certain how to proceed.Neither is most of the academic community.However, prior work done at USC offers special opportunities to address this question.
