高速公路限速对提高行车安全起到了重要作用,但是却牺牲了高速公路“高速”的优越特性。随着汽车新技术和智能交通技术的发展,目前高速公路计算行车速度120km/h的限制终究将会被突破。为了适应未来计算行车速度高于120km/h的高速公路发展需求,论文首先提出了超高速公路的概念,对超高速公路技术等级进行了划分,然后对超高速公路的可行性进行了论证,最后对超高速公路发展的必要性进行了深入研究。
Speed limit on the highway to improve driving safety has played an important role, but at the expense of highway “speed ” superior features. With the development of new technologies and intelligent transportation technologies, the current limit of 120km / h calculated by the expressway will eventually be exceeded. In order to meet the demand of expressway development in the future when the driving speed is higher than 120km / h, the paper first proposes the concept of expressway, divides the technical grade of expressway, and then demonstrates the feasibility of the expressway. Finally, The necessity of the development of the expressway has been studied in depth.
