  Augmented by Foo Hee Meng, David Ong, Yang Shao Fa (17 Jun 99)



  GIS-Related
  -----------
  Short-Term:
     Rendering Module
       Allow Zooming In and Out
         with several levels of map-scale
       Panning
         navigate top, down, left, right
       Display street names at detail level
         (subject to data availability)

     Computation
       Total distance to travel
       Trip time
       Fare information

     Search
       by road name (subject to data availability)
       by stops

     Model/View architecture


  Long-Term:
     Handle different map data/industry map formats

     Display some prominent landmarks 

     Support different modes of transportation (taxi/private car/LRT)

     Annotation of map and locations

     Automatic scaling based on source/destination locations

     Dynamic data (live-feed)

     Search
       by location, prominent landmarks, neighbourhood proximity
       by category (according to street directory)

     Support multiple "user-profiles"



  GUI-Related
  -----------
  Short-Term:
    Load a pre-defined map

    Display map and map-scale

    Display bus route given bus number
      in text form/on the map
      start and end station, schedule/frequency, number of stops
      total distance, trip time, fare information (min/max)

    For a bus-stop, show all buses going thru it

    Optimization Criteria
      # of transfers, time taken, fare
  
    Optimal Route Display (rough)

    Search
      by road name (subject to data availability)
      by stops



  Long-Term:
    File menu
      open a map-database (handle different maps/map formats)
      save a session
  
    Data Edit
      move/insert/delete bus stops
      change bus route
      modify bus schedule
      update other bus stop info

    Additional bus info
      non/partial/full air con

    Additional optimization criteria
      total distance travelled, display # of bus stops

    Tourist Spots
      display them on the map
      select fro Menu
      Display nearby buses/MRT
        and how to get there (+ frequency info)
        fare information
  
    Compute several alternative near optimal routes
  
    Incorporate some coarse measure of tradeoff
      example diff of 10 cents is OK, but ...
      diff of 3 minutes not significant, want to look at frequency
  
    Calculation of route distances

    Search
      by location, prominent landmarks, neighbourhood proximity
      by category (according to street directory)

    Optimal Route Display
      different levels of details
        rough, intermediate, full-details
      split windows

    Support printing, map annotation

    Animation of optimal route



LONGER TERM PLAN:
-----------------
   Supply user with random choice of places to visit

   Supply user with full day schedule given list of places to visit

   Help user plan entertainment for the day (what to buy, see, etc)
