A Decentralized Network Consensus Control Approach for Urban Traffic Signal Optimization
Gerardo Lafferriere
The main contribution of this project is the simulation platform that allows for comparison between the proposed consensus approach and a standard traffic signal control protocol. The main features of the mathematical model and the simulation tools are explained and illustrated in the report. The complete open source for the code is available in the online depository. The code is in the form of MATLAB files with extensive comments explaining the various parts of the model. The tool has an int...
