In this study, the Highways Agency provides real-time traffic and vehicles composition, and in accordance with the respective number of lanes, and simulates the highway capacity utilization and the expected implementation after exclusive bus lane. According the traffic of 338-370 km, there are three lanes, four-lane and five-lane in the direction. At three-lane, the general lanes at 15:00 to 16:00 and 20:00 to 21:00, the lane usage is almost close to 100%, and exclusive bus lane usage only up to the maximum 20%, showing planning and implementation of bus lanes when there is still room for growth shift; and from 15:00 to 16:00 and 20:00 to 21:00 general lane will reduce to 45 kilometers per hour, other times are still more than 75 kilometers per hour, exclusive bus lanes can reach more than 90 kilometers per hour. At four-lane, the general lanes at 15:00- 17:00 lane usage up to 85%, and the exclusive bus lane usage of up to 35%; and general lane except 15:00to 17:00 average driving speed is only 82 kilometers, slightly lower than the current situation; the others have increased 3 to 17 km. Meanwhile, the average travel speed of exclusive bus lanes, have increased 10 to 17 kilometers per hour, and100 km per hour averagely. At five-lane, the general lanes usage are 65%at 14:00-17:00, and bus lanes lane usage only up to 30%.Reducing of traffic interference, the average travel speed can remain 85 km, and the average driving speed of exclusive bus lanes can improve 6 ~ 12 km, which shows the exclusive bus lane at highway will reduce the situation of mixed traffic, can promote road capacity, the average travel speed at general lanes can improve, and the average travel speed of bus lanes can have good performance, too. |
