國道都會地區路段交通改善成果

The Results of Freeway Congested Improvements for Metropolitan Areas

重現性壅塞係指在特定時段與可預知的路段常發生因道路容量不足與交通需求過度集中所產生之壅塞；為解決上述壅塞情形，交通部高速公路局於106年至108年針對多處重現性壅塞路段，利用大數據資料分析與觀察國道主線路段及交流道之交通變化，找出重現性壅塞路段之型態及成因，並規劃有效改善方案，改善壅塞情形，以提供更便捷、舒適且安全之國道運輸服務。

Recurrent congestion is caused by insufficient capacity, excessively centralized traffic demand and usually occurs at specific time and in predictable section. To solve this problem, Freeway Bureau had aimed specific sections of freeway from 2017 to 2019. With analyzing big data and observing the traffic variation of mainlines and interchanges, we had searched out the reasons and the types of recurrent congestion. Through short-term and low-cost traffic engineering and management methods, we successfully improve the congested situation. Now that we can provide more convenient, more comfortable and safer service of freeway transportation.
