The goal of this repository is to create a side-by-side comparison of transit buses with combustion engines with those that are electric to advise policy in Mexico City.
Obtaining all the data was completed without any on-vehicle sensors. The process started by obtaining the shapefile route of each transit bus in Mexico City. These were then projected into a different coordinate refrence system to make them easier to work with [CRS Projection]. Then, elevation for points across the route were queried to calculate the gradient [Gradient Querying]. Next, traffic and speed data were utilized to create a speed profile of the area during different seasons and times of the day [Speed Querying]. This profile and the gradient data were then spatially joined and used to create a complete drive cycle with a one second resolution [Cycle Generation]. Finally, using these drive cycles along with bus specifications, a simulation software named FASTSim was employed to predict the difference in energy consumption profiles of electric and combustion engine along these routes [Simulation].
The data used in this project comes from the following sources:
- Bus Route Shapefiles [add source]
- Waze Speed Data [https://wazeopedia.waze.com/wiki/USA/Traffic_data]
