Costs may be either line lengths or attributes saved in a database table. These attribute values are taken as costs of whole segments, not as costs to traverse a length unit (e.g. meter) of the segment. For example, if the speed limit is 100 km / h, the cost to traverse a @@ -14,16 +14,16 @@

DESCRIPTION

Supported are cost assignments for arcs, and also different costs for both directions of a vector line. For areas, costs will be calculated along boundary lines. +

The input vector needs to be prepared with v.net operation=connect in order to connect points representing center nodes to the network.

Points specified by category must be exactly on network nodes, and the input vector map needs to be prepared with v.net operation=connect. -

The flag -t enables turntable support. +This flag requires additional parameters, turn_layer and turn_cat_layer, +that are otherwise ignored. The turntable allows to model e.g. traffic code, where some turns may be prohibited. This means that the input layer is expanded by turntable with costs of every possible turn on any possible node @@ -161,7 +161,7 @@

TURNS SUPPORT

-The turns support was implemnented as part of GRASS GIS turns cost project +The turns support was implemented as part of GRASS GIS turns cost project at Czech Technical University in Prague, Czech Republic.
Eliska Kyzlikova, Stepan Turek, Lukas Bocan and Viera Bejdova participated in the project.
