Topic 3: Boundary Zone Starvation & Dynamic Buffering Policies
Quantifying service blackouts across East River cross-borough portals (Manhattan - Queens - Brooklyn - Bronx) during inclement weather.
Root Cause of Boundary Zone Starvation:
Fixed static dispatch zones cause Manhattan core drivers to reject cross-river trips (58% - 71% Rejection Rate) due to fear of outer-borough deadhead traps, while outer-borough drivers deadhead straight into Manhattan to chase surge. Consequently, Long Island City, Williamsburg, and Greenpoint experience a 78% fleet deficit, stranding passengers for over 30 minutes in rainstorms.

Dynamic Boundary Buffering & Return Trip Guarantee Framework:
1. Priority Return Trip Guarantee: Drivers completing drop-offs in LIC/Williamsburg are automatically queued for high-yield Manhattan return dispatches at bridge portals, compressing ETA from 28 min down to 8 min.
2. Boundary Buffer Incentives ($4.00 - $5.50/trip): Micro-subsidies allocated from congestion surcharge funds directly compensate cross-borough river crossings during storm peaks.
