Route Systems

Routes
 Each route in a route system is defined as a series
of one or more line features. The route system is
one map layer, and the line features are stored in
another layer in the map. Here are some
examples:
– A designated highway route composed of a series of
highway line features
– A truck route based on a series of streets between
delivery points
– A bus route defined by the series of streets over which
the bus travels
– A subway route operating over elevated, surface, and
underground rail line features

Routes
 When defining a route system, each line feature
that is part of a route is referred to as a segment.
Every route is made up of a series of segments.
Several routes in a route system may operate on
the same segment. A route can also include
segments more than once. A route can be
continuous, with all of its segments connected to
each other. A route can also have gaps or spaces
in it.
 A route system can have:
– No stops, such as a highway inventory
– Route stops, such as truck routes with delivery points
– Physical stops and route stops, such as a bus system or
railroad with stations, time points, etc.

Physical Stops
 In TransCAD, physical stops are inventory of
places where route stops can occur. They are
most often used for transit or rail routes and
indicate the locations of stations, junctions, or
signs along the routes.
 If the route system has physical stops, then route
stops must be at physical stops. If you want to
add a route stop where there is no physical stop,
or move a route stop to where there is no physical
stop, TransCAD will ask you to enter information
for a new physical stop first.

Creating and Editing a Route
System
 There are four basic steps you need to
follow to create a route system:
– Identify or create the line layer on which the
route system will be based
– Create a network file for the area covered by
the route system
– Create an empty route system file using the
File-New command
– Use the Route System toolbox to create and
edit the routes

Setting the Route System Edit
Options
 The route system edit method gives you
two ways to indicate where a route should
go:
– Shortest Path uses a network file to find the
segments on the shortest path, based on a field
that you specify, between the points that you
indicate along the route.
– Click Segments lets you indicate the specific
segments that the route should follow. You
must be sure that the segments form a
continuous path, and that you do not go the
wrong way on a one-way segment.

To Realign One or More
Selected Routes
Before you use this instruction,
you have to select a route first
Click on the point on the route where the realignment
will begin, click on additional points as needed, and
double-click on the point on the route where the
realignment will end.
