Capacity drop accounting for microscopic vehicle interaction effects: analytical model and validation with high-resolution trajectories

Ludovic Leclercq, Pan Liu, Yu Han, Zhiyuan Liu

An analytical model shows capacity drop arises from acceleration delays in hesitant vehicles and their wave-void interactions.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

This interaction is the key mechanism behind the differing extents of capacity drop observed between standing queues and jam waves in previous studies.

C2weakest assumption

The spatial and temporal distributions of hesitant vehicles together with their delay durations are known or can be reliably estimated independently of the capacity drop data being modeled.

C3one line summary

Analytical model attributes capacity drop to total void length from hesitant vehicles, with downstream-upstream wave interactions explaining differences between standing queues and jam waves, validated on simulations and trajectories.
