RouteProbe detectors are meant to determine the route distribution for all vehicles that passed an edge in a given interval. Their real-world equivalent would be a police stop with questionnaire or a look into the database of navigation providers such as TomTom.
Instantiating within the Simulation
RouteProbe Detectors have to be defined within an additional-file which has to be loaded by the simulation.
<additional> <routeProbe id="<ROUTEPROBE_ID>" edge="<EDGE_ID>" freq="<FREQUENCY>" file="<OUTPUT_XMLFILE>"/> </additional>
The following attributes are used within the routeProble element:
|Attribute Name||Value Type||Description|
|id||id (string)||The id of the routeProbe element (user choice)|
|edge||id (string)||The id of an edge in the simulation network|
|freq||time (s)||The frequency in which to report the distribution|
|file||string||The file for generated output|
|begin||time (s)||The time at which to start generating output|
<route-probes> <routeDistribution id="r3/1to2/1_80.00"> <route id="r1_80.00" edges="4/1to3/1 3/1to2/1 2/1to1/1 1/1to0/1" probability="1.00"/> </routeDistribution> </route-probes>
RouteProbe elements can be used in conjunction with Calibrators where route distributions are required when inserting new vehicles.
