From 30.000 feet

JTRROUTER computes routes that may be used by SUMO based on traffic volumes and junction turning ratios.

Purpose: Building vehicle routes from demand definitions using junction turning percentages
System: portable (Linux/Windows is tested); runs on command line
Input (mandatory):
A) a road network as generated via NETCONVERT or NETGENERATE, see Building Networks
B) a demand definition, see Demand Modelling
C) Junction turning definitions
Output: Definition of Vehicles, Vehicle Types, and Routes usable by SUMO
Programming Language: C++

Usage Description

JTRROUTER is made for routing based on turn-ratios.

Options

You may use a XML schema definition file for setting up a JTRROUTER configuration: jtrrouterConfiguration.xsd.

Configuration

All applications of the SUMO-suite handle configuration options the same way. These options are discussed at Basics/Using the Command Line Applications#Configuration Files.

Option Description
-c <FILE>
--configuration-file <FILE>
Loads the named config on startup
--save-configuration <FILE> Saves current configuration into FILE
--save-template <FILE> Saves a configuration template (empty) into FILE
--save-schema <FILE> Saves the configuration schema into FILE
--save-commented <BOOL> Adds comments to saved template, configuration, or schema; default: false

Input

Option Description
-n <FILE>
--net-file <FILE>
Use FILE as SUMO-network to route on
-d <FILE>
--additional-files <FILE>
Read additional network data (districts, bus stops) from FILE(s)
-r <FILE>
--route-files <FILE>
Read sumo routes, alternatives, flows, and trips from FILE(s)
-t <FILE>
--turn-ratio-files <FILE>
Read turning ratios from FILE(s)
