Random traffic generation

• Python script for SUMO
• C:\Program Files (x86)\Eclipse\Sumo\tools\randomTrips.py

Python libraries for SUMO

• You can generate random traffic using network.net.xml file (road network)

  1. Create your own workspace (folder)
  2. copy randomTrips.py

  python randomTrips.py -n network.net.xml -r test.rou.xml
  

  • Other options
    • -b: begin time
    • -e: end time
    • -p: period
    • --binomial: maximum simultaneous arrivals

O/D matrix and route

• Origin and destination matrix

• O/D matrix can be converted as below (od_file.od)

• The first line is a format specifier that must be included verbatim
• The lines starting with '*' are comments and can be omitted
• The second non-comment line determines the time range given as
  • HOUR.MINUTE HOUR.MINUTE
• The third line is a global scaling factor for the number of vehicles for each cell
• All other lines describe matrix cells in the form FROM TO NUMVEHICLES

From O/D matrix to route
