Optimization of traffic organization at the connection section between urban expressways and expressways
城市快速路与高速公路衔接段的交通组织优化

摘要

城市快速路与高速公路衔接段作为重要的交通枢纽，承担着城市与周边高速公路之间的交通流量转换。由于衔接段存在交通瓶颈，导致交通流畅度差、通行效率低、事故频发等问题，影响了交通安全和城市交通的顺畅运作。本文通过分析当前城市快速路与高速公路衔接段的交通组织现状，提出了优化交通流线设计、信号控制和交通标识的策略，旨在提高衔接段的通行能力和安全性。通过优化设计，提高交通效率和减少事故发生，将有效提升整个交通系统的运营水平。

Abstract

As an important transportation hub, the connection section between urban expressways and expressways undertakes the conversion of traffic flow between cities and surrounding expressways. Due to the existence of traffic bottlenecks in the connection section, problems such as poor traffic smoothness, low traffic efficiency, and frequent accidents occur, affecting traffic safety and the smooth operation of urban traffic. This paper analyzes the current status of traffic organization at the connection section between urban expressways and expressways, and proposes strategies to optimize traffic flow design, signal control, and traffic signs, aiming to improve the traffic capacity and safety of the connection section. Through optimized design, improving traffic efficiency and reducing accidents will effectively enhance the operational level of the entire transportation system.
