Problems solved by technology
At present, some cities in China, including Beijing and Hangzhou, have implemented travel policies, but there is currently a lack of effective methods for evaluating peak travel policies, making many travel policies based on subjective decisions, and the implementation effect often has to wait until peak travel Only after the policy is implemented can it be evaluated

Embodiment
[0085] A method for evaluating peak-staggered travel policy based on reverse traffic allocation, including the following steps:
[0086] (A) Construct forward basic road network, such as image 3 shown;
[0087] The parameters of the forward basic road network section are shown in Table 1;
[0088] Table 1 road section parameter table
[0089] road section free flow time Capacity 1 10 100 2 10 400 3 5 600 4 5 300 5 10 200 6 5 300 7 5 300
[0090] (B) According to the distribution of commuter travel time from home, such as Figure 4 As shown, the traffic demand during the morning peak period (6:15-9:45) is allocated to the forward basic road network described in step (A) using the static traffic allocation method every 5 minutes, and the commuting before peak shift is obtained The time distribution of travelers reaching their destinations is as follows: Figure 5 shown;
[0091] (C) Construct the reverse base roa...

The invention discloses an off-peak travel policy evaluation method based on reverse traffic distribution. The off-peak travel policy evaluation method comprises the following steps: (A) constructinga forward basic road network; (B) according to time distribution of travelers starting from home, distributing OD demands before peak shifting to the forward basic road network in the step (A) by adopting a multi-time static traffic distribution method; (C) constructing a reverse basic road network; (D) according to the peak shifting travel policy, delaying the working time of part of travelers for a period of time; (E) according to the time distribution that the traveler arrives at the destination after peak shifting, distributing the reverse OD demand after peak shifting to the reverse roadnetwork in the step (C) by adopting a multi-time static traffic distribution method; and (F) comparing the road section traffic volume and travel time allocated in the step (B) and the step (E) in thepeak period, and evaluating the peak shifting travel policy. According to the method, the peak shifting travel policy can be reasonably evaluated, and reference is provided for formulation and implementation of the peak shifting travel policy.
Description
technical field [0001] The invention relates to a reverse traffic distribution technology, which belongs to the field of traffic policy evaluation, and in particular to a method for evaluating a peak shift travel policy based on reverse traffic distribution. Background technique [0002] With the rapid development of China's urbanization process, the problem of urban traffic congestion is becoming more and more serious. Practice has proved that blindly strengthening the construction of traffic infrastructure is not a good way to solve traffic congestion, and a large number of people and vehicles flow in a relatively concentrated time. The main cause of urban traffic congestion. [0003] Peak-staggered travel is a common traffic demand management measure, and its purpose is to balance traffic flow in time and alleviate the contradiction between supply and demand. OD demand refers to the travel demand between the origin and destination of the trip, that is, the traffic volume...
