A
- application
- An application is a computer program, herein, an "application" mostly means one of the main, compiled programs that are included in the SUMO package.
- additional-file
- A file that can be included in a sumo configuration. This is needed to load pois, shapes, bus stops and variable speed signs. Refer to the format description for details.
C
- connection(s)-file
- An XML-file describing connections between edges or lanes, see connection descriptions for importing networks defined as XML
D
- DELPHI
- Deutschlandweite Echtzeit Verkehrs-Lage und Prognose im Ereignisfall
- destination
- The position of the end of a vehicle journey. Mostly a TAZ processed by OD2TRIPs within which a "sink" edge lies
- detector
- An artificial device for object (mainly vehicle) states recognition and/or logging
- DFD
- Deutsches Fernerkundungsdatenzentrum des DLR
- district
- see TAZ
- DLR
- Deutsches Zentrum für Luft- und Raumfahrt
- DUA
- Dynamic User Assignment
- DUE
- Dynamic User Equilibrium
E
- edge
- A single-directed street connection between two points (junctions/nodes). An edge contains at least one lane
- edge(s)-file
- A XML-file describing edges of a road network, see edge descriptions for importing networks defined as XML
F
- FCD
- Floating Car Data
I
- induction loop
- A detector placed on a certain position on a lane which recognizes vehicles passing it and logs their attributes (speed, size, etc.)
J
- junction
- The place an edge begins or ends at (same as node)
- junction logic
- The part of a junction which determines the vehicle behaviour at the according junction by using certain right-of-way - rules
L
- link
- A connection between two lanes within a junction. Within microsim, each lane has links (connections) to the following lanes. A link contains the information whether the vehicle has to decelerate in front of the junction.
M
- macroscopic
- In a macroscopic traffic (flow) simulation, the atomic instances are roads; the flow is simulated directly (see microscopic)
- mesoscopic
- In a mesoscopic traffic (flow) simulation, the streets are partitioned into sections which multiple vehicles may enter and leave at each simulation step
- microscopic
- In a microscopic traffic (flow) simulation, the atomic instances are vehicles; the flow is simulated by simulating the vehicles (see macroscopic)
- multimodal
- A multimodal traffic simulation is capable of processing different types of traffic (busses, trains, vehicles etc.)
N
- (street) network
- In our terms, a network is the combination of junctions (nodes) and edges (streets)
- node
- A node (junction) is a single point were at least one edge (road) starts or ends
- node(s)-file
- A XML-file describing nodes of a road network, see node descriptions for importing networks defined as XML
O
- O/D-matrix (od-matrix)
- Origin/Destination-matrix; describes how many vehicles are moving from each origin to each destination within a certain time period
- option
- A parameter for the application which determines what or how an application shall do
- origin
- The position of the begin of a vehicle journey. Mostly a TAZ processed by OD2TRIPs within which a "source" edge lies
P
- poi
- short for "point of interest"; A position of an object that may be interesting
R
- route
- A route is a complete description of a vehicle's path over the network; it contains the information when the vehicle departs (the route starts) and over which edges the vehicle shall drive
S
- script
- A small computer program which normally doees not have to be compiled. The SUMO package includes several scripts, most written in Python
- source
- A source means a place at which vehicles are inserted into the street network
- source-tar-ball
- A file containing the sources (program code) for a project. The source code must be compiled in order to get the runnable application. It is called "tar-ball" because of using the application "tar" to join all the source files into a single file.
- submicroscopic
- In a submicroscopic traffic (flow) simulation, the atomic instances are parts of the vehicle or the driver (gearing or behavior is modelled)
T
- TAZ
- Traffic Assignment Zone, a collection of edges describing a part of a road network's area (also called 'district')
- TLS
- traffic lights system
- trip
- A reduced information about a vehicle's movement; contains only the departure time, the begin, and the end edge. Must be transformed into a route using a router for being used within the simulation
- trip-table (trip list)
- A file containing several trips
- TS
- Institute of Transportation Systems at the German Aerospace Center (DLR)
- TS-BS
- TS Standort Braunschweig
- TS-BA
- TS Standort Berlin-Adlershof
- type(s)-file
- A XML-file describing types of streets, see type descriptions for importing networks defined as XML
X
- XML
- "eXtensible Markup Language is a universal format for structured documents and data" as the w3c says. Further information may be found at http://www.w3c.org/XML/ or http://en.wikipedia.org/wiki/XML. Most of the data read and written by SUMO is stored as XML, see also the page on file types.
- XSD
- XML Schema Definitions "... provide a means for defining the structure, content and semantics of XML documents" as the w3c says. Further information may be found at http://www.w3.org/XML/Schema or http://en.wikipedia.org/wiki/XML_Schema_%28W3C%29. A part of the XML data formats used by SUMO is covered by xsd, see the page on file types.
