碩士 === 淡江大學 === 運輸管理學系 === 89 === Recent development in Dynamic Route Guidance System (as a subsystem of Advanced Travel Information System) has called for more studies in the subject of users’ compliance behavior, which affect the effectiveness of the provided in-vehicle roue guidance information. Although field test may be promising in a long run, large initiated capital investment will be involved and may not be appropriate in the early stage of system development. Laboratory experiment provides an economical alternative approach to handle this particular issue with great flexibility. A prototype of laboratory simulator has therefore been established from previous studies in this institute under Dr. Tong''s supervision as a dedicated tool of controlled experiment to collect such observations due to economical and practical considerations. This simulator is a computer based simulation system to mimic the basic functions of a DRGS of which provides traffic condition, navigation, and route guidance information through screen display. This particular design (SIM 1.0) includes five modulus components: a display module, a record module, a data base module, a computation module and a user operation interface module, and has proven its capability from a series of completed experiments. The objective of this thesis is to modify and to extend the flexibility of the prototype simulator. Two major modifications needed are (1) to add the network selection function instead of a fixed (default) experiment network, and (2) to integrate a traffic simulation program onto this original prototype system to substitute original survey-based fixed-timed traffic data base. These two modifications will allow the further studies to in-cop with experiment design technique to investigate more in-depth issues regarding the trilateral interactions of user/traffic network/information with DRGS. Accomplished in this thesis are three tasks. Firstly, a preliminary survey was conducted to explore the role of traffic network characteristic (which we found that was largely ignored by transportation related research articles). Secondly, analysis of the original simulator program and the selection/decomposition of the specific traffic simulation program were performed in order to realize the integration with programs in different computer languages. Finally, a series of tests were carried out to ensure seamless integration Results of this study have clearly demonstrated the justification of the issue of network characteristic within a DRGS context and the successful limited modification to current simulator with a selected traffic simulation program DYNASMART. Possible full-scale integration issues were also presented in this thesis which leads to more challenges for further studies
