City of Redondo Beach Travel Demand Modelling
The purpose of this project is to introduce the Travel Demand Forecasting (TDF) model built for the City of Redondo Beach with CUBE version 6.4. This report describes the model development and updating based on the source data originally validated in the year of 2008, provides forecasts of future travel demand in the year of 2028, and includes traffic impact analysis of an assumed comprehensive development project in Study Area 15. The citywide model contains 17 study areas (1-16, and 18) composed of 175 Traffic Analysis Zones (TAZ). Study Area 15 and 16 are the concentration of this report, which are made up of TAZ 5 – 8 and 1 – 4 respectively. Three scenarios are built to analyze traffic impacts, including base year (2008), future without project (2028) and future with project (2028).
Impacts of the Project
The proposed project will contribute to a 0.5% increase on the total traffic volume in the study area. The links close the proposed project site in TAZ 3 will witness the largest increase of volume, V/C ratio and delay time in the residential area south of TAZ 3. Highly affected intersections are those of arterials or other higher level of facilities in this system, which corresponds to the assignment of trips to arterials instead of local/collectors
Proposed Solution
Due to the considerable impact on the arterials and associated intersections, we suggest widening the Inglewood Ave and Manhattan Beach Blvd and the surrounding arterials intersections to accommodate the forecasted traffic growth. Additionally, bike share programs might be considered for this area to provide sustainble travel modes as well as reduce VMT.
