The tools' names accord to their function.
Allows to verify whether routes within the given route-file(s) are valid for the given network. Call(s):
routecheck.py <net> <vehicletypes> [-f|--fix] <routes>+
routecheck.py <net> <vehicletypes+routes>
If a route is broken (a diconnected), the tool writes something like the following to cout: Template:Warning
If --fix (-f) is given, routes are tried to be repaired (assuming only one link is missing). The name of the output file(s) is generated by appending ".fixed". These file contain repaired routes (if it was possible), each appended link is written in comments after the vehicle.
- The tool does not deal with vehicle types; it only checks whether routes are connected
- When working in --fix-mode a vehicle type file must be given
- No tests for dealing with networks that have internal edges
Joins routes belonging to two networks. A map file with the following syntax is read first:
It describes at which edges the networks overlapped and which edge was kept in the resulting one. Vehicles from both given route files starting at the first of those edges will be at first not regarded, but their routes are kept in memory. All other vehicles are kept, but if they pass one of the mapped edges, the route is continued by choosing a random route from the list of previously discarded ones which start at the corresponding edge.
routes_Join.py <prefix#1> <routes#1> <prefix#2> <routes#2> <mapfile>
- <prefix#1>: The prefix to use for vehicles from the first routes file
- <routes#1>: The first routes file
- <prefix#2>: The prefix to use for vehicles from the second routes file
- <routes#2>: The second routes file
- <mapfile>: The edge mapping
Attention! The routes are not sorted in time!
This script sorts the vehicles in the given route file by their depart time. If the option --big is supplied, a slow but memory efficent algorithm is used.
<SUMO_HOME>/tools/route/sort_routes.py input.rou.xml -o output.rou.xml
This script cuts down routes from a large scenario to a sub-scenario. This assumes the existence of a big scenario (orig.net.xml and orig.rou.xml). The goal is to simulate only a smaller part of the network (reduced.net.xml) keeping all of the routes that pass through the reduced network. Output can be a route file or a trip file. Depending on the given options the new departure times can be computed from exitTimes (see SUMO option --vehroute-output.exit-times), extrapolated from the original network or simply copied from the original departure times. If the option --big is supplied, a slow but memory efficent algorithm is used for sorting the output by departure time. Example usage
<SUMO_HOME>/tools/route/cutRoutes.py reduced.net.xml orig.rou.xml --routes-output output.rou.xml --orig-net orig.net.xml
Filtering stopping places is also supported by setting the options --additional-input and --stops-output.
Compute a length-histogram for all routes in a given route file. Alternatively, compute the difference in lengths for two route files with the same vehicles. Routes must be child elements of <vehicle>-elements. Output for plotting may also be generated (see --help).
<SUMO_HOME>/tools/route/routeStats.py myNet.net.xml myRoutes.rou.xml
When setting option --attribute depart a histogram on departure times (or departure time differences) is generated instead.
Transform routes into polygons for visualization in SUMO-GUI. Using the options --hue, --saturation, --brightness the colors can be controlled. Each of these options supports values from [0, 1] as well as the special value random.
<SUMO_HOME>/tools/route/route2poly.py myNet.net.xml myRoutes.rou.xml
Transform routes into an edge selection file which contains all edges used in any of the routes, trips or person plans. This file may be used for visualization in SUMO-GUI or pruning a network via NETCONVERT.
<SUMO_HOME>/tools/route2sel.py myRoutes.rou.xml -o usedEdges.txt
netconvert --net-file myNet.net.xml --keep-edges.input-file usedEdges.txt --output reduced.net.xml
Shifts the departure times of <vehicle>, <trip>, and <flow> elements by a specified amount. When setting the option --depart-edges Edge1,Edge2,..., only vehicles that depart on one of the given edges are affected.
<SUMO_HOME>/tools/route/route_departOffset.py --input-file myRoutes.rou.xml --output-file shifted.rou.xml --depart-offset 900
The option --depart-interval a,b,c,d shifts all departures within the interval [a,b[ to the interval [c,d[.
<SUMO_HOME>/tools/route/route_departOffset.py --input-file myRoutes.rou.xml --output-file shifted.rou.xml --depart-interval 3600,7200,0,500
Generates a visualization file for investigating traffic patterns in a route file.
<SUMO_HOME>/tools/showDepartsAndArrivalsPerEdge.py myRoutes.rou.xml --output-file results.xml
The option --intermediate may be used to include the total number of passing vehicles for each edge in the generated output.
The generated file result.xml can be loaded in SUMO-GUI to color edges by number of departs, arrivals or total number of passing vehicles
When investigating routes that pass a particular edge or intersection, the input routes may be filtered using the option --subpart <STRING>:
<SUMO_HOME>/tools/showDepartsAndArrivalsPerEdge.py myRoutes.rou.xml --output-file results.xml --subpart edge3,edge4,edge5
This will only generate results for routes that contain the edge sequence edge3 edge4 edge5.
To declare a vehicle that stops in a parkingArea, a <stop>-definition must be part of the vehicle or it's route. This script adds stops to routes.
<SUMO_HOME>/tools/addStops2Routes.py -r <route-file> -p <parking-areas> -d <duration in seconds> [-o <output-file>]
Stops in one or more parking areas (seperated by comma) are added to the vehicles route, if they are part of the vehicles id. Example:
<routes> <vehicle id="0_parkingAreaA" depart="0"> <route edges="e1 e2 e3"/> </vehicle> </routes>
<SUMO_HOME>/tools/route/addStops2Routes.py -r <route-file> -p ParkingAreaA -d 3600 [-o <output-file>]
<routes> <vehicle id="0_parkingAreaA" depart="0"> <route edges="e1 e2 e3"/> <stop parkingArea="parkingAreaA" duration="3600"> </vehicle> </routes>
Note, that the lane of that parking area must belong to one of the edges "e1, e2, e3" of the vehicles route.
This script maps a list of (geo) coordinates to a consecutive list of edges in a given network (a route)
<SUMO_HOME>/tools/route/tracemapper.py -n <net-file> -t <trace-file> -o <route-output-file>
The input contains the coordinates for every vehicle in a single line. Example:
vehicle1:363.66,497.79 2008.64,498.82 vehicle2:363.66,497.79 1498.46,989.78 2008.64,498.82
The output is a standard sumo route file
<routes> <route id="vehicle1" edges="beg rend"/> <route id="vehicle2" edges="beg left2end rend"/> </routes>
The option --geo enables the conversion of the input coordinates with the parameters given in the network. The mapping algorithm is also available in the python library function sumolib.route.mapTrace.
This script is to calculate the turn ratios or turn movements from a link to its downstream links with a given route file. The output file can be directly used as input in jtrrouter, where the time interval will be set for one day. The call is
<SUMO_HOME>/tools/generateTurnRatios.py -r <route-file>
The standard output is the traffic volumes. With the option -p turning ratios will be calculated and outputted.
This script is to adapt the cycle lengths of the signalized intersections according to a given network and route file. The Webster's equation is used to optimize the cycle length and the green times of the traffic lights. Only one hour traffic volume is considered and PCE is used instead of the number of vehicles when calculating traffic volumes. The output will be saved in a xml-file and can be directly used as additional file in SUMO. The call is
<SUMO_HOME>/tools/tlsCycleAdaptation.py -n <net-file> -r <route-file> -b <begin>
The signalization parameters, such as minimal green time, lost time, yellow time, maximal and minimal cycles, can be adjusted with the use of options. Option R is to restrict the maximal cycle length as the given one, while Option u is to use the calculated max cycle length as the cycle length for all intersections. With Option e only the green time splits will be adapted.
