“…Lane-changing behavior is becoming a significant concern in the research community. Many researchers have investigated this issue by proposing new or modified models [3][4][5][6][7], by simulating lane-changing behaviors in micro-or macro-scenarios [5,[8][9][10][11][12], or by analyzing field data from traffic sensors [3,4,[13][14][15][16].…”

“…For mandatory lane changes, Cao et al [3] presented an exploratory study of lane change execution and proposed a lane-changing behavior model on arterial roads. For off-ramp areas, Liu et al [6] presented a second-order partial differential equation model that was used to simulate both compulsive lane-changing behavior and free lane-changing behavior.…”

Congestion has become a significant issue in recent years and has greatly affected the efficiency of urban traffic operation. Random and disorderly lane-changing behavior greatly reduces traffic capacity and safety. This paper is mainly concerned with the relationship of lane-changing spacing intervals provided by off-ramp facilities and traffic flow conditions. Through field investigations in Beijing, several typical lane-changing behaviors at off-ramp areas are analyzed. By using field traffic data and actual road geometry parameters, VISSIM-based micro-behavior simulations at off-ramp areas are implemented to obtain traffic flow conditions with different lane-changing spacing intervals and other model parameters, such as traffic volume and ratio of off-ramp vehicles. Then, the numerical relationships between traffic flow state and model parameters can be shown. The results show that with increasing traffic volume and the ratio of off-ramp vehicles, the lane-changing spacing interval required by vehicles should be increased. For the same ratio of off-ramp vehicles, if the traffic volume increases by 100 pcu/h/lane (pcu is a unit to stand for a standard passenger car), the corresponding lane-changing spacing interval should be increased by a spacing of 50–100 m to avoid increasing congestion. Based on the results of this paper, smart lane management can be implemented by optimizing lane-changing spacing intervals and lane-changing behaviors to improve traffic capacity.

“…Ye et al (2017) used a Bayesian network model to investigate the association between breakdowns and parameters prior to breakdowns at on-ramp bottlenecks. Liu et al (2016) presented a second-order partial differential equation model for simulating compulsory lane-changing behaviors and free lane-changing behaviors. A form of this model that focuses on compulsory lane changing that is caused by off-ramp areas is derived.…”

Purpose The purpose of this study is to effectively optimize vehicle lane-changing behavior and alleviate traffic congestion in ramp area through the study of vehicle lane-changing behaviors in upstream segment of ramp areas. Design/methodology/approach In the upstream segment of ramp areas under a connected vehicle environment, different strategies of vehicle group lane-changing behaviors are modeled to obtain the best group lane-changing strategy. The traffic capacity of roads can be improved by controlling group lane-changing behavior and continuously optimizing lane-changing strategy through connected vehicle technologies. This paper constructs vehicle group lane-changing strategies in upstream segment of ramp areas under a connected vehicle environment. The proposed strategies are simulated by VISSIM. Findings The results show that different lane-changing strategies are modeled through vehicle group in the upstream segment of ramp areas, which can greatly reduce the delay of ramp areas. Originality/value The simulation results verify the validity and rationality of the corresponding vehicle group lane-changing behavior model strategies, effectively standardize the driver's lane-changing behavior, and improve road safety and capacity.

“…The core of two-lane traffic flow research is to establish a realistic lane change model to study the influence of lanechanging disturbance on road traffic flow, and in this aspect, scholars have made some meaningful attempts. [24][25][26] Typically, Rickert et al proposed a set of lane-changing rules in 1996, [27] and later, Chowdhury et al presented a symmetric two-lane CA model (abbreviated as STNS model) in 1997. [28] A similar lane change model to that in STNS was adopted by the famous simulation software TRANSIMS (short for transportation analysis and simulation system).…”

Traffic flow velocity disturbance characteristics and control strategy at the bottleneck of expressway

In the three-phase traffic flow studies, the traffic flow characteristic at the bottleneck section is a hot spot in the academic field. The controversy about the characteristics of the synchronized flow at bottleneck is also the main contradiction between the three-phase traffic flow theory and the traditional traffic flow theory. Under the framework of three-phase traffic flow theory, this paper takes the on-ramp as an example to discuss the traffic flow characteristics at the bottleneck section. In particular, this paper mainly conducts the micro-analysis to the effect of lane change under the two lane conditions, as well as the effect of the on-ramp on the main line traffic flow. It is found that when the main road flow is low, the greater the on-ramp inflow rate, the higher the average speed of the whole road section. As the probability of vehicles entering from the on-ramp increases, the flow and the average speed of the main road are gradually stabilized, and then the on-ramp inflow vehicles no longer have a significant impact on the traffic flow. In addition, this paper focuses on the velocity disturbance generated at the on-ramp, and proposes the corresponding on-ramp control strategy based on it, and the simulation verified that the control strategy can reasonably control the traffic flow by the on-ramp, which can meet the control strategy requirements to some extent.
