OD2TRIPS generate negative probability making Sumo impossible to run when those conditions are met:

  • Small amount of vehicles (under 10) between 2 locations in the origin-destination input matrix
  • flow-output and flow-output.probability parameters are used
  • timeline and timeline.days-in-hours parameter are used (small probability around midnight 0.5%)

Output examples:
<flow id="10" begin="7200.00" end="10800.00" probability="-0.000255" fromTaz="a" toTaz="b" departLane="free" departSpeed="max"/>
<flow id="12" begin="7200.00" end="10800.00" probability="-0.000264" fromTaz="a" toTaz="c" departLane="free" departSpeed="max"/>

Probability should be limited between 0.00 and 1.00.
