Method and system for determining the shortest elapsed time route

A method for determining the shortest elapsed time route among plural routes connecting a first location and a second location for a user as a reference, each of said plural routes comprises plural route segments, said method comprising the steps of:

• a) establishing a transformation table recording corresponding relationships of traffic volume and average driving time in each of said plural route segments;
• b) acquiring a traffic volume in each of said plural route segments depending on a departing time of said user;
• c) acquiring an average driving time according to said transformation table;
• d) accumulating said average driving time of each of said plural route segments in each of said plural routes;
• and
• e) selecting a route having the lowest accumulated average driving time.

A system for determining the shortest elapsed time route among plural routes connecting a first location and a second location for a user as a reference, each of said plural routes comprises plural route segments, said system comprising:

• plural wireless stations, installed at a first end and a second end of each of said plural route segments for receiving identification information transmitted from wireless communication devices in automobiles traveling in each of said plural route segments;
• a computer device communicated with said wireless stations for recording information of the time that each of said automobiles arrives in each of said first end and said second end of each of said plural route segments;
• and
• an optimum route planning system, acquiring information from said computer device and determining the shortest elapsed time route among said plural routes according to said information and data inputted by said user and notifying said user of said shortest elapsed time route.
