Activity-Travel Simulation Using Detailed Spatio-Temporal Data and Interactive Surveys

本研究的目的是修正活动-出行调度模型，以评估交通政策措施，如TDM和个体约束的缓解。研究结果如下：1。利用GPS和PHS技术开发了创新的时空旅行行为数据采集与分析系统。为期一周的旅行调查可以分析来自GPS数据的旅行时间变化，并通过比较PHS数据和自我报告的问卷调查数据，分析旅行次数和旅行开始/结束时间。总结了该系统在实际应用中的进一步发展。构建路网和公共交通网络位置和活动机会开放时间的时空GIS数据库，为仿真模型的输入数据和交互调查的背景数据提供所需数据。3 .利用交通需求、交通供给和活动机会的详细时空数据，建立了一种能够处理接送行为和引入两人活动计划约束的多日活动的替代活动模式生成模型，并对老年人家庭的接送行为进行了分析。将活动模式生成模型与GIS相结合，开发了基于GIS的活动-旅行游戏仿真工具。该工具应用于老年家庭，以便了解家庭特定的限制条件，并模拟对变化的反应。

The objectives of this study are to modify activity-travel scheduling models, which aims to evaluate transportation policy measures such as TDM and mitigation of individual constraints. The results are the followings :1. Innovative spatio-temporal travel behavior data collection and analyzing systems were developed using GPS and PHS.One-week travel surveys enabled the analyses of travel time variability from GPS data and the analyses of the number of trips and trip start/end time by comparing PHS data with self-reported questionnaire survey data. Further developments of the systems to the practical use were summarized.2. Spatio-temporal GIS database of road network and public transport network location and opening hours of activity opportunities were constructed, which are needed for input data of simulation models and background data of interactive surveys.3. Using detailed satio-temporal data of transport demand, transport supply and activity opportunity, an alternative activity pattern generation model which was able to deal with pick-up behavior and multi-day activities introducing two persons activity schedule constraints were developed and pick-up behavior in the elderly households was analyzed.4. A GIS-based activity-travel gaming simulation tool was developed linking the activity pattern generation model with GIS.This tool was applied to the elderly households so that household-specific constraints were understood and responses to changes were simulated.
