-
- Thank you for giving GRIDLOCK a try. GRIDLOCK is a shareware
- program. That means that you can try it without paying too much
- money for it. If you decide to use it, you are expected to
- register the program with the author and pay him for it. The
- price is only $25. In return, you will get such good things
- as telephone help if you need it, notification of updates, a
- map of the area where the game takes place, some very useful
- charts, and one fairly good solution to the traffic problem.

- ABOUT THE GAME
-
- GRIDLOCK gives you a section of a city and lets you control its
- traffic by selecting the types of traffic lights or stop signs to
- put at the intersections and setting the lengths of the cycles.
- The computer provides most of the traffic to test your designs
- while you get to program the routes of two test cars.
-
-
-
- EQUIPMENT NEEDED
-
- GRIDLOCK is designed for IBM PCs or compatibles with at least
- 512K bytes of RAM and EGA or VGA color graphics. Your computer
- should have a clock-speed of at least 16 MHz. (Slower computers
- slow down the action but even at 10 MHz the speed is still
- tolerable.) The computer should have version of 3.2 or higher
- of the DOS operating system. The game is played from the
- keyboard. No mouse or joy-stick is needed.
-
-
-
- THE FILES AND HOW TO RUN THEM
-
- The files that you should have on your disks are these:
-
- README this message
- GL.EXE the GRIDLOCK program
- GRIDLOCK.RTS must be on the disk with GL.EXE
- GRIDLOCK.DAT saves game conditions, must be on
- the disk with GL.EXE
- GRIDLOCK.TXT the instructions
-
- To read the instructions from your screen, put the diskette with
- GRIDLOCK.TXT on it into drive A, set the computer to drive A, and
- type TYPE GRIDLOCK.TXT. If you can print them out on a printer,
- reading is much easier. To print them, type PRINT GRIDLOCK.TXT.
- Or you can use your word processing program to read or print this
- ASCII file.
-
- To play the game, put the diskette with the file GL.EXE and
- the files GRIDLOCK.RTS and GRIDLOCK.DAT into drive A, set the
- computer to drive A, and type GL <ENTER>. Or you can copy these
- files to the hard disk and run them from there.
-
- Getting the disk started can be speeded up if you haven't stored
- the conditions of a previous game or you don't care about starting
- with those conditions. In that case, start the game by entering
- GL SKIP instead of just GL. That makes the computer skip the
- reading of the .DAT data file.
-
-
-
- THE OBJECTIVES OF THE GAME
-
- One object of the game is to design a system of traffic controls
- that will let maximum traffic flow without getting hopelessly
- blocked intersections (gridlock). That isn't easy to accomplish.
- Another object of the game is to design the traffic system so
- that the test cars drive their routes in the shortest amounts
- of time.
-
-
-
- LEARNING THE GAME
-
- When you first turn on the program, it is suggested that you try
- the RUN option (3) of the main menu first. (Select some medium
- amount of traffic when asked - say 40% - and choose not to speed
- up traffic.) Then watch the cars. Watch how traffic flows
-
- without any traffic controls and see where it is the heaviest.
- You can change the amount of traffic by pushing F1 and selecting
- the RUN option again. After you have studied the traffic, try
- putting in some traffic controls using option 1 of the main menu.
- You will want to switch back and forth between these options,
- making changes in the lights and then testing them in the RUN mode.
- (If you have heavy traffic on the screen, stop the RUN mode to
- change a traffic light, and then re-start the RUN mode, there is a
- small chance that cars in the changed intersection could find
- themselves in trouble and have an accident. To prevent that,
- clear the traffic before you re-start the RUN mode.) After you
- have designed some traffic systems, you can program the two test
- cars, using option 2, to see how your systems compare with each
- other.
