In order to trust and use autonomous vehicles, safe driving on the road must be guaranteed. For this, the first infrastructure to be equipped with autonomous driving is traffic safety facility. On the other hand, autonomous vehicles(Level 3) and general vehicles are driving on the road, it is necessary to additionally manage existing general traffic safety facilities. In this study, a field management system for traffic safety facilities based on autonomous driving infrastructure was studied, and a pilot field management system was implemented in the demonstration area(Pangyo). The pilot system consists of a GNSS(Global Navigation Satellite System) receiver, a field management equipment, and a field management app. As a result of field demonstration,, it was confirmed that traffic safety facility information was easily transmitted and received even in downtown areas and that could be efficiently operated and managed. It is expected that the results of this study will be used as reference materials for the spread of autonomous driving infrastructure to local governments and infrastructure construction in the future.

Intelligent Transportation Systems(ITS) enables road users to enhance efficiency of their trips in a variety of traffic conditions. As a significant part of ITS, information communication technology among vehicles and between vehicles and infrastructure has been being developed to upgrade current traffic data collection technology through location-based traffic surveillance systems. A wider and detailed range of traffic data can be acquired with ease by the technology. However, its performance level falls with environmental impediments such as large vehicles, buildings, harsh weather, which often bring about wireless communication failure. For imputation of vehicle trajectory data discontinued by the failure, several potential existing methods were reviewed and a new method to complement them was devised. AIMSUN API(Application Programming Interface) software was utilized to simulate vehicle trajectories data and missing vehicle trajectories data was randomly generated for the verification of the method. The method was proven to yield more accurate and reliable traffic data than the existing ones.

In order to provide the drivers with more reliable transportation information in NHTMS(National Highway Transportation Management System), it is important to estimate the expected passage time by using the traffic volume and speed. In this study, we analyze the characteristics of the traffic volume in the national highway and we investigate two real-time adjustment methods: the average adjustment method and the auto-regressive adjustment method. In addition, we compare them using the real data collected at the National Highway Route 3 in 2000.

현재 차량 항법 장치는 최근 급속하게 발달한 전자기술을 활용하여 단순한 차량의 자유이동 기능에서 운전자에게 안전성, 효율성, 편의성, 가격 등을 보장할 뿐만 아니라 운전자에게 경로를 안내하거나 교통 정보를 제공하는 정보 제공 장치로 도약하고 있다. 그러나 앞으로 이같은 단순 정보 전달 기능을 초월하여 보다 효율적이고 안전한 운행이 가능한 지능적인 기능을 수행케 될 것이다. 즉, 도로상의 센서와 같은 교통 정보 수집체계와 통신체계 등을 활용하여 실시간 교통 상황 정보를 제공하여 쾌적한 추행환경 및 차량 제어 시스템과 연계하여 안전주행에 기여할 수 있다.

국내에 교통학이 도입된 지 20여년이 지나 어느정도의 학문적 성숙단계에 올라 있어서 국내 교통분야의 연구경향과 학문적 성과를 정립할 필요가 있지만, 아직까지 국내 교통연구의 체계적 정리나 분석이 이루어지지 않고 있는 실정이다. 본 논문에서는 교통관련 논문들을 비교분석함으로써 국내 교통연구분야의 연구경향과 추이를 분석하고, 장래의 학문적 연구방향을 고찰하였다. 교통학회지와 토목학회지, 국토도시계획학회지의 3개 학회지를 대상으로 비교분석한 결과, 이론적 논문이 증가하고 교수와 연구원 중심으로 연구가 진행되고 있다는 결론을 도출하였고, 실무자를 위한 실증적 연구분야의 계획 필요성이 요구된다.

이선하 교수는 광역교통망, 지역간선도로망, 철도망 구축방안을 제시하면서, 동시에 이들 사업에 대한 투자우선순위를 비롯한 재원조달방안 등에 대한 검토도 병행되어야 한다고 주장하였다. 발표논문의 주요 내용을 요약하여 전재한다.
