Modeling and Analyzing the Environmental and Traffic Impacts of Ride-Hailing Services Using Eclipse MOSAIC

Core Concepts

Leveraging the Eclipse MOSAIC simulation framework to model and analyze the traffic and environmental impacts of different rebalancing strategies for ride-hailing services.

Abstract

The paper presents a simulation-based approach to model and analyze ride-hailing services using the Eclipse MOSAIC framework. The key aspects are: Input data analysis: Examined logbook data from a middle-sized ride-hailing fleet in Berlin, Germany. Analyzed the different scenarios that occur after a ride is completed, such as accepting a follow-up order or returning to the point-of-business. Identified that return mileage plays a significant role, accounting for over 30% of the total mileage. Ride-hailing model: Implemented a ride-hailing model using the Application Simulator in Eclipse MOSAIC. Modeled the dynamic nature of ride-hailing, including ride order generation, vehicle assignment, and route planning. Integrated the model with the large-scale Berlin traffic scenario (BeST) to capture the impact on overall urban traffic. Experiments: Defined three rebalancing strategies for drivers after completing a ride: return to point-of-business (baseline), wait at drop-off location, and drive to a nearby hotspot. Generated artificial logbooks based on the input data to overcome limitations of the original dataset. Conducted a simulation study to analyze the traffic and environmental impacts of the different rebalancing strategies. Results: The Wait and Hotspot strategies showed significant potential for reducing total mileage (up to 24% and 18% respectively) and CO2 emissions (up to 25% and 18% respectively) compared to the baseline. Extrapolated the findings to the entire ride-hailing fleet in Berlin, estimating potential annual savings of 70 million km in mileage and 7.25 tons of CO2 emissions. The paper demonstrates the effectiveness of using a simulation-based approach, enabled by the Eclipse MOSAIC framework, to model and analyze the complex dynamics of ride-hailing services and evaluate the impacts of different operational strategies.

Deeper Inquiries

How could the simulation model be extended to incorporate more advanced dispatching and rebalancing algorithms, and what would be the potential impacts on the results

To extend the simulation model to incorporate more advanced dispatching and rebalancing algorithms, several steps can be taken. Firstly, the model can be enhanced to include dynamic dispatching algorithms that consider real-time factors such as traffic conditions, demand fluctuations, and driver availability. This would involve implementing algorithms that optimize the assignment of drivers to ride requests based on various criteria like proximity, waiting times, and overall fleet efficiency. Additionally, more sophisticated rebalancing strategies can be integrated, such as predictive analytics to anticipate demand surges and strategically position vehicles in high-demand areas. These advanced algorithms would likely lead to more efficient fleet utilization, reduced idle times, and optimized routing, ultimately resulting in lower overall mileage, reduced emissions, and improved service quality.

What other factors, beyond rebalancing strategies, could be investigated to further improve the efficiency and sustainability of ride-hailing services (e.g., vehicle electrification, ride-sharing, etc.)

Beyond rebalancing strategies, several other factors could be investigated to enhance the efficiency and sustainability of ride-hailing services. One key area is vehicle electrification, where transitioning to electric vehicles (EVs) can significantly reduce emissions and environmental impact. Implementing a fleet of EVs powered by renewable energy sources could lead to substantial reductions in greenhouse gas emissions and air pollutants. Additionally, promoting ride-sharing and pooling initiatives can further optimize vehicle occupancy rates, reduce the number of vehicles on the road, and decrease overall congestion and emissions. Integration with public transportation systems, infrastructure improvements for alternative modes of transport, and the adoption of eco-friendly practices like eco-driving techniques and vehicle maintenance can also contribute to a more sustainable and efficient ride-hailing ecosystem.

How could the insights from this study be applied to other transportation modes or shared mobility services to reduce their environmental and traffic impacts

The insights gained from this study can be applied to other transportation modes and shared mobility services to mitigate their environmental and traffic impacts. For instance, the optimization strategies developed for ride-hailing services, such as dynamic dispatching and efficient rebalancing, can be adapted to public transportation systems to improve route planning, reduce waiting times, and enhance overall service quality. Similarly, the concept of predictive analytics and real-time data integration can be utilized in bike-sharing programs, carpooling services, and micro-mobility solutions to streamline operations, increase user satisfaction, and minimize environmental footprint. By leveraging the principles of simulation modeling and data-driven decision-making, various transportation modes can be transformed to be more sustainable, efficient, and user-friendly.
