Equity Outcomes and Potential for Better Bike Share
John MacArthur
Nathan McNeil
In a mere ten years, public bike-sharing systems have exploded from operating in a few select European cities to expanding in North America at a pace of nearly two dozen cities per year in recent years. The majority of academic research to date has focused either on the complex logistics of designing and operating systems or else on broad comparisons across systems. Investigations of system users and local impacts have only just begun. As cities plan and launch their systems, a tension has ar...

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...
