초록

기존의 동적 통행배정모형은 출발시간 선택에 있어서 도착시간제약을 고려하지 못하고 있으며, 이를 고려하더라도 수단분담을 고려하지 못하거나 별도의 문제로 다루고 있다. 따라서 대중교통의 수단분담비가 높고, 도착시간에 대한 제약이 따르는 출근·통학통행이 주류를 이루는 오전첨두시의 교통관리·분석을 위해서는 이들을 동시에 고려하는 동적 통행배정모형이 요구된다. 본 연구에서는 Ran과 Boyce가 구축한 모형에 기반하여 통행수단과 도착시간 제약에 따른 출발시간 선택을 경로선택과 동시에 고려할 수 있는 통합모형을 제시하였다. 모형의 풀이를 위해 Ran과 Boyce가 사용한 시·공간 확장 가로망을 새롭게 설계하여 사용하였으며, 가상 가로망에 적용하여 모형의 적합성을 검증하였다. 사례연구 결과 본 연구에서 제시한 모형이 동적 사용자최적 통행배점상태를 나타내는 것을 확인할 수 있었고, 이를 통해 오전 첨두시의 교통관리·분석을 위해 적용 가능함을 입증하였다.

A dynamic transportation management should be applied specially in AM peak because AM peak is more critical than PM peak in traffic volume and demand. AM peak trip can be characterized by commuting and schooling. which have the high level of usage on public transportation, and constraint on arrival time. So transportation management applied in AM peak could deal with a mode choice and an arrival time constrain. Researchers were involved in the dynamic transportation assignment models for management of congested traffic network. But, there were no models which considered a mode choice and an arrival time constrain should be included in management of AM peak. So there are limits to use exist models to control and analyze AM peak traffic. In this study, it is proposed the combined dynamic transportation model, considering a mode choice and the start time selection with arrival time constrains, based on Ran and Boyce's model. The proposed model is verified the compatibility by applying to the newly designed time space expanded network. The result shows that proposed model consistent with dynamic user optimal travel pattern. From this we certificate the applicability of the proposed model to control and analyze AM peak traffic.
