1. Car will accelerate (a=gu) until it reach maximum speed under the following condition:
there is no car in front and it can pass the next street light before light turn red.
2. Car will de-accelerate(a=-gu) until it reach zero velocity if it is too close to the car just in front of it.
The minimum distance is related to reaction time, dmin= V * treaction.
3. Car will keep at the same speed if it reach maximum speed.

To you access the applet you need to unzip the file that you download before, will find a web page name is trafficControl.html hit click using mouse,
You will be able to watch applet in your PC.

If you just need to view it offline. Click get file for offline use and you should get .zip file.
Unzip it and open html file with your browser. (the instruction is available as email message  if you decided to received it via email.)

You can download the java source code,too!
The file you have download should be trafficControl.java instead of php file.
The file can be open with any text editor, it can be compiled into java class code.

1. The code at this topic was created more than 10 years ago with JDK1.0.2
You might want to check out Ejs version of traffic control simulation and working with EJS.

2. Please write down what you have done (or what you know about java or programming)?
The timing for red,green,blue light are the same for those three traffic lights (and it can be changed with mouse click--left click to decrease or right click to increase).
You need to define a new GUI to change one of the traffic light, and modify the value for them it the code.
It seems to be an exercise for you. I will try to help but I should not do the job for you.

Hi.

I just registered on the forum, being interested in the traffic applications. I found this topic and tried to see how the application work, but I was unable to access it.
When I access the first page of the topic the browser crashes. It works on the other pages of the topic though. I tried with several browsers, and also with different internet providers (home, school ... etc.). It's the same - the first page is somehow broken.
Same thing happens with the link you provided about the newer EJS version.

So in the end, I was unable to see the application running, or at least get the files and make it work by myself somehow. Could you help me with this?

Thank you.

Best wishes,
Leutz

main class is for java application. The code is for creating java applet.
I am not familiar with NET BEANS , however, I think you need to change your selection from application to applet.

It was written as an applet (more than 10 years ago) instead of an application (so there is no main in the code).

You can use appletviewer to view it. (need an html page with applet tag)

Please check out sun's web site and find out more information.

You can check out traffic light control applet with EJS. You can download jar file version which can be run as an application. (just double click the downloaded ajr file).
And you can modify it with EJS and create new version,too!
