/** @file
|
21 |
* @brief Contains code related to finding a route from a position to a destination
|
22 |
*
|
23 |
* Routing uses segments, points and items. Items are items from the map: Streets, highways, etc.
|
24 |
* Segments represent such items, or parts of it. Generally, a segment is a driveable path. An item
|
25 |
* can be represented by more than one segment - in that case it is "segmented". Each segment has an
|
26 |
* "offset" associated, that indicates at which position in a segmented item this segment is - a
|
27 |
* segment representing a not-segmented item always has the offset 1.
|
28 |
* A point is located at the end of segments, often connecting several segments.
|
29 |
*
|
30 |
* The code in this file will make navit find a route between a position and a destination.
|
31 |
* It accomplishes this by first building a "route graph". This graph contains segments and
|
32 |
* points.
|
33 |
*
|
34 |
* After building this graph in route_graph_build(), the function route_graph_flood() assigns every
|
35 |
* point and segment a "value" which represents the "costs" of traveling from this point to the
|
36 |
* destination. This is done by Dijkstra's algorithm.
|
37 |
*
|
38 |
* When the graph is built a "route path" is created, which is a path in this graph from a given
|
39 |
* position to the destination determined at time of building the graph.
