Dataset for the Electric Vehicle Routing Problem with Time Windows given the Altitude Information

This is the dataset used in the experimental study of the paper entitled “Uphill Struggles, Downhill Gains: How Road Gradients and Load Dynamics Influence Electric Vehicle Routing Decisions?” by Rastani et al. (2025). This paper deals with the Electric Vehicle Routing Problem with Time Windows by taking into account the effect of road gradient and regenerative braking on energy consumption, which is referred to as the EVRPTW-GR. The instances are generated using the EVRPTW instances of Schneider et al. (2014), modified by Rastani et al. (2025).
