Traces
Traces are presented as an xml file, more specifically as an routes input file for SUMO simulation (schema definition).
Every individual trace is assigned to a predefined vehicle and has following attributes:
id- an unique id with prefix indicating an hour of simulation ("_h0_0" : vehicle number 0 in 0 hour of simulation)type- a type of vehicledepart- the departure time in secondsdepartLane- a lane the vehicle is tried to be inserteddepartPos- a position on the chosen departure lane at which the vehicle is tried to be inserteddepartSpeed- the speed of the vehicle at insertion
See more information about routes in SUMO simulation.
The route itself is a sequence of edges from .net.xml file (schema definition).
See more about SUMO network presentation.
Example of .rou.xml file:
<routes>
<vehicle id="_h0_1" type="306" depart="0.0"
departLane="free" departPos="pwagGeneric" departSpeed="max">
<route edges="95025018 27467064 ... 5122537#3"/>
</vehicle>
<vehicle id="_h0_2" type="cx" depart="0.0"
departLane="free" departPos="pwagGeneric" departSpeed="max">
<route edges="75627908#7 75627908#8 ... 26452488#3"/>
</vehicle>
...
</routes>
All sets of traces use the same vehicle types defined in the beginning of rou.xml file:
<vType accel="2" color="1,0,0" decel="7" id="porsche"
length="4" minGap="2" maxSpeed="50" sigma="0.6"/>
<vType accel="1.7" color="0.4,1,0.4" decel="6" id="206"
length="4" minGap="2" maxSpeed="40" sigma="0.5"/>
<vType accel="1.7" color="0.4,0,1" decel="6" id="306"
length="4.5" minGap="2" maxSpeed="40" sigma="0.5"/>
<vType accel="1.4" color="0.4,0.8,1" decel="6" id="twingo"
length="3.5" minGap="2" maxSpeed="35" sigma="0.8"/>
<vType accel="1.1" color="0.9,0.9,0.9" decel="5" id="cx"
length="5" minGap="2" maxSpeed="35" sigma="0.5"/>
<vType accel="1.05" color="0.1,0.1,0.1" decel="4" id="truck"
length="15" minGap="2.5" maxSpeed="30" sigma="0"/>
