According to the statistics, the density of freeway in Taiwan is 291.6 km/10,000 km2, which is ranked fifth worldwide after Singapore, Hong Kong, South Korea, and Germany. The average daily traffic has reached 1.52 million/time. To deal with the requirement of high volume and quality transportation, the highway linear and geometric design is highly related to driver’s traffic safety. Highway geometric design is divided into horizontal alignment, vertical profile, cross-section, and so on. Poor design of highway geometric will influence the driver’s judge and his driving behavior, increasing the probability of accident. In view of understanding the relevance of freeway alignment and accident, it is necessary to study the relationship. National Freeway No. 3, also called Formosa, is Taiwan’s longest highway of length 432.9 km and the second north-south highway. The main function of National Freeway No. 3 is to share the almost full traffic loading of Freeway No. 1, and also has the goal of balancing the urban and rural development. The line of Freeway No. 3 mainly goes through the western towns and rural areas, while promoting the development along the region. This study was to explore the interaction of characteristics of road sections between Xiangshan and Changhua, the traffic, and the factors of accident. The study was expected to understand the pattern of road alignment and accidents, and tried to identify the road sections of more accidents. Then an appropriate improvement and warning plan can be prepared for the accident prone roads.
