Electric Vehicle Trip Energy Consumption Data
The data consists of normal driving records for dozens of private cars over several months (from June 5, 2015 to June 30, 2016), with a sampling frequency of one minute. The basic specifications of the vehicles are as follows: Roewe E50 is a pure electric vehicle, weighing 1080 kilograms. It is equipped with a 22.4 kWh battery pack, and is reported to have a driving range of 170 kilometers. The raw data has been preprocessed and denoised, resulting in a final dataset containing 10,000 trips. This dataset offers substantial potential for reuse in research and analysis focused on electric vehicle energy consumption. Researchers, engineers, and policy makers can leverage this data to understand patterns, develop optimization algorithms, and inform energy-efficient practices. The dataset adheres to all applicable legal requirements. All sensitive information has been removed, and the data has been preprocessed to ensure confidentiality. There are no known legal or ethical obstacles to its use.

Training and Application Code of the MDP Driving Policy in Highway
The dataset comes from the paper "Markov probabilistic decision making of self-driving cars in a highway with random traffic flow: a simulation study" and mainly consists of three parts:
1. The "policy_training" folder, which includes the code used for training driving strategies in the highway scenario mentioned in the paper. The main function is "main_v3.cpp," and the functionality is implemented in the file "f_define_v3.cpp." Additionally, "to_strategy.m" exports the trained strategy as a state-action table for application, and "FIGURE.me" visualizes this table.
2. The "policy_application" folder contains "test.py" as the main file, which uses "MdpModel.py" to call the state-action table from the "Strategy" folder and visualizes it through "MdpModel.py." The "Map" and "Vehicle" folders store visualization elements.
3. The third part is a video of the visualization results named "simulation_demo.avi."
Vehicle and charging scheduling of electric bus fleets: a comprehensive review
Purpose — Transit electrification has emerged as an unstoppable force, driven by the considerable environmental benefits if offers. Nevertheless, the adoption of battery electric bus is still impeded by its limited flexibility. The constraint necessitates adjustments to current bus scheduling plans. To this end, this paper aspires to offer a thorough review of articles focused on battery electric bus scheduling.
Design/methodology/approach — We provide a comprehensive review of 42 papers on electric bus scheduling and related studies, with a focus on the most recent developments and trends in this research domain.

The data used in this work is accessible through order in the space geodetic coordinate system.xls (coordinates of 200 orders in the space geodetic coordinate system) and 1kmzone_wsg_xy.csv (the latitude, longitude, and geodetic coordinates of the center of each 1km * 1km area).
For each business mode, a python file is provided individually. For instance, mode1_truck_trailer.py is for mode 1, mode2_truck_drone.py is for mode 2 and mode3_drone_socialvehicle.py is for mode 3. The time, cost and energy consumption can be derived directly from these files.
A topology-based bounded rationality day-to-day traffic assignment model
The MATLAB code is the implementation of the model presented in the article 'A topology-based bounded rationality day-to-day traffic assignment model. The software allows to represent the evolution of the road network state when subjected to a disruptive event and is composed of 3 fundamental elements.
-The main_Equilibrium.m function implements the Frank-Wolf algorithm for the computation of the User Equilibrium. This makes it possible to know the traffic flow patterns on the original network.
-The Disruption.m and ShockAssignment.m functions take care of constructing the new network following the disruption and routing the flows directly affected by the network topology changes.
-The function DTD_TrafficAssignment.m implements the proportional switch traffic assignment model presented in the aforementioned article. For each period, at each iteration, the amount of flows moving from more expensive paths to less expensive paths is calculated.
