Route Guidance Model with Limited Overlap on Freeway Network under Traffic Incidents
Table 1
Route guidance procedure.
Step
Initial Input: Network parameters (topology, free-flow speed, and capacity) OD information (demand, origin, and destination) Detector setup (lane position and detector type)
1
SUMO simulator: generate vehicle trajectories For all link , and vehicle :
2
Statistical time interval and the traffic diversion
3
Initialize a dict to store data, including edge flow and edge impedance
4
Collect statistical data on ,, and
5
Guide based on the type of incidents
6
During the guidance period, with a time interval of 5 minutes: First, calculate travel time on link :
Then, calculate route impedance and the probability of choosing the path
Allocate vehicles to the guided path based on the
7
Update the according traffic volume.
8
Control vehicle operation until the guidance is completed
