You can download the source code, and use/modify it with NetLogo (quicker than with a browser, need NetLogo version 2.1 or higher) But since in real traffic the configuration is constantly changing, it seems that we would do better with an adaptive mechanism than a mechanism which is optimal some times, and some times creates havoc (and it is too expensive to try to find all possible optimal solutions, since the configuration space is too huge and uncertain.).įor the technicalities and further descriptions, you can read the paper Self-Organizing Traffic Lights. Optimization gives the best possible solution for a given configuration. Traffic is not so much an optimization task, but an adaptation task, since traffic flows and densities change constantly. Traffic lights try to "self-organize" for improving traffic. This simulation was exended from the model "Gridlock" by Uri Wilensky & Walter Stroup, which comes with NetLogo 2.0.0 (see more info at the bottom) On other operating systems, you may obtain the latest Java plugin from Web browser under Safari/Preferences/General.) Mac users must have OS X 10.2.6 or higher and useĪ browser that supports Java 1.4. The applet requires Java 1.4.1 or higher.
