Roads and Maritime Services, NSW commissioned Bitzios Consulting to undertake a trip generation and parking demand survey and analysis of Car-Based High Density Residential buildings. The Road’s and Maritime Services Guide to Traffic Generating Developments – 2002 (hereafter referred to as the Guide), contains traffic generation and parking demand information based on surveys completed in 1993. This has recently been updated in a 2013 Technical Direction of the Guide based on a 2012 study. Roads and Maritime Services recognised that previous studies have looked at sites generally close to high frequency - high capacity public transport. In recent years there has been a trend towards higher density residential developments along corridors not necessarily well serviced by public transport. Roads and Maritime Services identified that new data is required focusing on residential developments that are considered “Car-Based” due to potential differences in the trip generation and parking generation compared to developments in public transport orientated centres.
