高度可靠的道路网络通过为司机提供替代路线来提供可靠和稳定的交通服务，即使网络的某一部分在灾难中遭到破坏。1989年洛马普里塔地震导致旧金山奥克兰海湾大桥关闭，给旧金山湾区公路网带来了严重的功能破坏。为了道路建设和交通管理的高度可靠的公路网，识别灾害的影响是相当重要的。然而，由于缺乏基础数据，日本还没有从交通角度进行灾害分析的机会。本文以旧金山湾区交通数据为基础，对路网的功能效应进行了分析。确定了地震前后路网容量、平均行程时间和码头可靠性的功能效应，包括评估与湾区快速交通(BART)的交通份额效应和额外的HOV(高占有率车辆)车道效应。
A highly reliable road network provides sure and stable traffic service by offering drivers alternative routes even when some part of the network is damaged in a disaster. The closure of San Francisco Oakland Bay Bridge caused by 1989 Loma Prieta Earthquake brought heavy functional damage on San Francisco Bay Area road network. For the purpose of road construction and traffic management for a highly reliable road network, the identification of effects of disaster is substantial. However, no opportunity of disaster analysis from the point of traffic view has been carried out in Japan due to the lack of basis data. This paper presents the analysis of functional effects of road network based on San Francisco Bay area traffic data. Functional effects of road network capacity, average travel time and terminal reliability are identified before and after the earthquake, including the evaluation of transportation share effects with BART (Bay Area Rapid Transit) and of the additional HOV (High-Occupancy-Vehicle) lanes effects.
