High-dimensional Data-driven Energy optimization for Multi-Modal transit Agencies (HD-EMMA)

This is a project funded by the Department of Energy, Office of Energy Efficiency and Renewable Energy (EERE), under Award Number DE-EE0008467. The research approach is to use continuous monitoring sensors on the complete mix of CARTA transit buses and to develop predictors and optimization mechanisms using the data. Specific activities are:

  • Acquire high-resolution (updated every minute) Spatio-temporal telemetry data from CARTA vehicles and exogenous data sources, such as traffic and weather
  • Develop an efficient framework to store and process the operational data and external data, including street and elevation maps
  • Create macro-level energy predictor using route information and general fleet parameters
  • Create a higher-resolution micro model that is tuned to specific vehicle parameters
  • Create an optimization framework to select the optimal assignment of vehicles to trips with the goal of reducing overall energy consumption
  • Develop a visualization framework to analyze the data

The following slide deck provides a brief overview of the project.
