Some clarity... or is it still confusion?

After a lot of searching through the six inches of space between my left and right ear, I understood that I will have to have a clear project definition before I go ahead.

So I started off with a empty board and scribbled all that I though was revelant to My Journey. The list is a complilation of various terms that I came across/remember to have come across during all these years on planet Earth! from various sources though some of them seem vauge.

• Travel Planning
• Source
• Destination
• Path
• Route
• Tour
• Transportation network
• Node
• Arc
• Impedence
• Length
• Distance
• Direction
• Turn
  
• Network analysis
• Least cost path
  
• Shortest distance
• Classical netowrk problems
• Travelling salesman problem
• Chinese postman problem
• GIS
• Modelling and representation of a network
• Maps
• WebGIS
• Online maps
• Online planning
• Internet
• Client Server technology
• e-Commerce
  
• Web Services

Looks like the list represents a picture (though hazy) (some sort of a collage of various concepts/technologies) of the problem at hand.
