Abstract EN
High volume of traffic is loaded on urban highway during peak hours as well as the ramp connecting main road and auxiliary road of highway.
Once the demand exceeds the capacity of the ramp, congestion may happen on both main road and the auxiliary road.
To deal with this problem, an new urban highway ramp, switchable ramp (SR) that can switch between on and off condition, is proposed in this paper.
A macroscopic time-space discrete model is built in this paper to model this process by dividing the studied time period into short time periods and the studied road segment into small sections.
The impact of the type of ramp on upstream and downstream traffic flow is analyzed.
A segment of urban highway in Chengdu, China, is used as a case study.
The traffic flow data in peak hours is collected and used.
Mathematical analysis proves that the SR system proposed in this paper can reduce the total travel time (TTT) in the studied area.
Results show that the SR system is more useful when the traffic volume is high.
