This phase had the team looking more at the software structure of how to implement an algorithm inside of SUMO. SUMO was heavily researched during this phase to better understand the usability of the program. Furthermore, the SUMO TraCI system was observed as this is where the algorithm will be gathering information and sending information back to.

It was decided by the team and customer to focus on real-time optimization, such that the algorithm developed will be deciding what to do for every situation it is presented with and ready to adapt to unusual events. For example, for a hockey game at RIT, there is a dramatic increase in the amount of traffic leaving RIT around approximately 9:30 PM on Friday/Saturday night. The algorithm should be able to recognize this and hold the lights green to let more cars out on the road instead of creating a traffic jam.

During this phase the team members began splitting the research work up by what their focus would be in the project, mostly by software development and program knowledge.

The end goal has stayed the same course - aim for a 20% reduction in emissions after applying the algorithm to an intersection.

Team Vision for Preliminary Detailed Design Phase

The team focused on learning Python, Git, and more about SUMO during this phase. The TraCI interface was also studied in depth. It is absolutely necessary to have a strong knowledge of the listed parts to be successful in this project.

Prototyping, Engineering Analysis, Simulation

Iterative activities to demonstrate feasibility, including assumptions you made in your analyses or simulations. Have you completed sufficient analysis to ensure that your design will satisfy requirements? Have you included all usage scenarios in your modeling?

Test Plan

The most common types of intersections have been determined to be shown above. There are also variances in number of lanes, existing left or right turn only lanes, etc. We plan to test multiple types of each intersection shown above.
