HIVE: Highly Integrated Vehicle Ecosystem Simulation Framework
NREL's Highly Integrated Vehicle Ecosystem (HIVE) framework simulates the operations of mobility-service-provider fleets.
HIVE's flexible design enables researchers to build large-scale simulation matrices and compare outcomes across scenarios that vary with respect to parameters such as:
- Locations and operating areas
- Vehicle types and fleet makeup
- Electric vehicle (EV) charging and fueling station networks
- Fleet operational behaviors and dispatching algorithms
- Economic factors and relevant policy considerations
- Customer behavior (i.e., willingness to pool or delay travel).
Approach and Uses
HIVE provides insight into how mobility service operations impact energy use, emissions, vehicle usage patterns, and levels of service. Researchers use this versatile tool to identify the number and types of vehicles necessary to support a known travel demand, project fleet performance in response to EV charging infrastructure availability, reduce traffic congestion, assess performance improvements attributed to increased passenger pooling, and more.
HIVE models vehicles and charging/fueling stations as individual agents that combine to form an integrated system. This approach to modeling enables detailed reporting at multiple levels of abstraction. For example, key performance metrics can be derived at the vehicle level, the vehicle-type level, or the vehicle-fleet level for any simulation. Similarly, electrical load profiles and utilization levels can be calculated for individual stations, combinations of stations, or across the entire network.
