The development of connected vehicle technology enables the coordinated control of vehicle group behaviors. This article investigates traffic flow characteristics in on-ramp areas from two aspects: road geometry length and lateral spatial distributions of traffic flow. The upstream and downstream flow-balance strategies for each lane in on-ramp areas are proposed. In different traffic conditions, various strategies are compared, and the advantages and disadvantages of these strategies and their application scopes are highlighted. The simulation results show that when traffic flow is low, the strategies of inducing all on-ramp vehicles to merge onto the outside lane of the main road are better. When the traffic flow is heavy, the strategies of inducing a particular ratio (e.g., 1:3:6) of on-ramp vehicles to merge onto the inside lane, middle lane, and outside lane work better and the downstream flow-balance strategies for each lane are better than the upstream flow-balance strategies. With the rapid development of information and communication technologies, the connected automatic vehicle technology will provide new ideas and methods for implementing the proposed flow-balance strategies. Therefore, research on the simulation of vehicle group behaviors in on-ramp areas can provide a theoretical basis and data support for ramp control and management, which has important guiding significance.

互联车辆技术的发展实现了对车辆组行为的协调控制。本文从两个方面研究了匝道区域的交通流特征：道路几何形状长度和交通流的横向空间分布。提出了匝道区域中每个车道的上游和下游流量平衡策略。在不同的交通状况下，比较了各种策略，并突出了这些策略的优缺点及其应用范围。仿真结果表明，在交通流量较低的情况下，诱导所有匝道车辆合并到主干道外车道的策略较好。当交通繁忙时，采用诱导特定比例（例如1：3：6）的匝道车辆合并到内部车道，中间车道，外部通道的工作效果更好，并且每个通道的下游流量平衡策略均优于上游流量平衡策略。随着信息和通信技术的飞速发展，互联自动车技术将为实施拟议的流量平衡策略提供新的思路和方法。因此，对匝道区域车辆行为的仿真研究可以为匝道的控制和管理提供理论依据和数据支持，具有重要的指导意义。互联自动车技术将为实施拟议的流量平衡策略提供新的思路和方法。因此，对匝道区域车辆行为的仿真研究可以为匝道的控制和管理提供理论依据和数据支持，具有重要的指导意义。互联自动车技术将为实施拟议的流量平衡策略提供新的思路和方法。因此，对匝道区域车辆行为的仿真研究可以为匝道的控制和管理提供理论依据和数据支持，具有重要的指导意义。
