METHOD FOR VISUALIZING A COMPLICATED METRO MAP IN A LIMITED DISPLAYING AREA
First Claim
1. A method for visualizing a complicated metro map in a limited displaying area, wherein said metro map contains a plurality of routes, each said route has a plurality of station nodes, each pair of adjacent station nodes are connected by an edge, and said method comprises steps:
- a. download a geographic metro map covering a focal routes and neighboring transportation networks between a start station node and a destination station node that are given by an user;
b. magnify station nodes and connecting said edges in said focal routes and deform said routes to determine a smooth metro map;
c. rotate said routes to lie in octilinear directions; and
d. label said station nodes of said focal routes with names.

Abstract
The prevented invention provides a method to visualize complicated metro maps in a limited displaying area, in which the route to the passenger'"'"'s destination is highlighted. In order to achieve high readability, it sets 1) the distance between neighboring stations to be equal, 2) the transportation lines to lie in octilinear directions, 3) the angles of incident edges at each station to be maximized, and 4) the station positions to be inside the displaying area. It also labels the names of stations that passenger will pass by to make the route navigation easy and intuitive.
