Transit Impacts on Jobs, People and Real Estate

Arthur C. Nelson Kristina Currans , Nicole Iroz-Elardo
Transit Impacts on Jobs, People and Real Estate, from the University of Arizona, represents the culmination of nearly a decade of research into the economic effects of transit. To unpack the dense and substantial findings from 17 LRT, 14 BRT, 9 SCT, and 12 CRT systems in 35 metro areas across the United States, the final report is split into five volumes. Arthur C. Nelson and fellow researchers Robert Hibberd, Kristina Currans and Nicole Iroz-Elardo of UA have completed the final phase of… Read More

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… Read More
