Trip generation surveys high density residential car based : data report

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新南威尔士州道路与海事服务局（Roads and Maritime Services, NSW）委托比齐奥斯咨询公司（Bitzios Consulting），针对汽车导向型高密度住宅建筑（Car-Based High Density Residential buildings）开展出行生成（trip generation）与停车需求（parking demand）调查分析工作。该局2002年发布的《道路与海事服务局交通生成开发指南》（Road’s and Maritime Services Guide to Traffic Generating Developments – 2002，下文简称《指南》），其收录的出行生成与停车需求信息基于1993年完成的调研，该指南于2013年依托2012年的研究成果完成修订并推出2013年版技术指引。道路与海事服务局注意到，过往相关研究的调研对象大多集中在紧邻高频大容量公共交通的站点周边地块，而近年来住宅开发密度提升的趋势逐渐向公共交通服务覆盖不足的沿线走廊延伸，该局意识到当前亟需针对汽车导向型（Car-Based）住宅开发项目开展全新的数据调研——相较于公共交通导向型开发项目，这类项目的出行生成与停车生成（parking generation）模式存在显著差异。
