Abstract: In household travel surveys, one effective way to improve the }response rate and accuracy is reducing the respondents’ burden. This paper proposes a GPS and internet based survey method. The GPS data loggers are used to collect vehicle track data for accurate trip, route identification, and trip purpose, while the web-based surveys collect the personal／household information from the survey respondents. Because of the high spatiotemporal accuracy of GPS travel data, the requirement of exact travel time can be decreased, and the respondents’ pressure reduction can be achieved. Moreover, the respondents are allowed to choose their appreciate time for the online survey. All these decrease the negative effects from undesirable factors or conditions. A case study is conducted among the faculty of East China Normal University to test the proposed approach. Results indicate that the passive GPS and web-based survey techniques could significantly improve the accuracy and efficiency of travel data collection and drastically reduce respondents’ burden and survey costs. This approach has potential advantages for the application on HTS.

摘要： 减轻受访者负担是提高居民出行调查回应率和精准度的关键，而基于传统问卷调查的改进对此难有突破. 本文设计和实验一种耦合GPS技术和网络调查技术的居民出行调查方案，以期获得实质性改善. 方案使用GPS模块进行被动式跟踪确定出行路径，同时利用网络调查收集受访者个人/家庭信息和行程目的. 设计利用GPS对出行时空轨迹具有高精准定义的特点，降低对行程信息调查表的填写要求，并且通过互联网调查允许受访者自行选择时间填写，把对行程回忆的不良影响减到最小. 方案实验使用了华东师范大学教职工群体做驾车出行调查，并与传统问卷调查做了比较. 试验的初步结果表明，新方案能够显著提高出行数据收集的精度和效率，明显降低受访者负担和调查费用，有望发展成为下一代交通调查的主要手段.
