Dataset: Transit agencies want open payments but there are challenges

Research Product Type
Data
This includes data used in the project, "All Aboard! Easier Transit Travel with Standardized Payments". The data was collected from California transit agencies in the fall of 2022 that gathered information about agency perceptions of open-loop payments and the challenges with adopting open fare collection systems, and whether assistance programs would benefit transit agencies interested in adopting open-loop payments.

Dataset: Summary of SB 743 implementation efforts by California's 539 cities and counties

Research Product Type
Data
The dataset centers around the level of service (LOS) to Vehicle Miles Traveled (VMT) shift which made the latter the transportation impact metric for land development projects under the California Environmental Quality Act (CEQA). Appropriately, this dataset summarizes the inventory findings of the study which investigated how local governments have been implementing the LOS-to-VMT shift for land development projects.

Dataset: Evaluating the effectiveness of “Smart Pedal” systems for vehicle fleets

Research Product Type
Data
The SmartPedalTM technology was evaluated using six Caltrans vehicles, each monitored for two data collection periods: 1) without the SmartPedalTM device, to collect the baseline data sets,  and 2) with the SmartPedalTM device, to collect a comparison data set with the “Smart Pedal” technology. The collected data is presented here.

Dataset: Developing a vehicle cost calculator to promote electric vehicle adoption among transportation network company (TNC) drivers

Research Product Type
Data
EV Explorer 2.0 includes several important features and functionalities to support the TNC driver use case that are not found in any other available tool: (1) It allows users to estimate TCO for used vehicles as well as new (others only estimate TCO for new vehicles); (2) Outputs include ridehail-driving income estimates, accounting for EV trip bonuses offered by Uber, net driving costs; (3) Estimates of total cost of driving (TCD) include charging network membership fees and charging session fees (in addition to electricity prices).

Simulation data for on-demand food delivery in Riverside, CA

Research Product Type
Data
In this research, the team studied a dynamic on-demand food delivery system and proposed a rolling horizon-based optimization approach integrated with adaptive large neighborhood search (ALNS) to efficiently obtain high-quality solutions. The system-level evaluation shows that on-demand food delivery has great potential to reduce dining-related VMT, resulting in significant reductions of fuel consumption and emissions, especially with Multi-R delivery policy.

Dataset: Vehicle trajectory data in Eco-friendly Cooperative Traffic Optimization (EcoTOp) system at signalized intersections

Research Product Type
Data
In this research, we will build upon this past research to develop a new cooperative traffic operation approach that takes advantage of not only infrastructure-to-vehicle communications, but also vehicle-to-infrastructure communications. This effort integrates a dynamic traffic signalization algorithm together with EAD algorithm to achieve even greater traffic efficiency.
