The update reduces extreme outliers in trip duration between drivers but may increase overall route length by 3–7% in exchange for fairer time distribution. 2. What Changed? (Technical Overview) | Feature | Pre-Update | Post-Update (Gini-enabled) | |--------|-----------|----------------------------| | Optimization goal | Minimize total fleet distance/time | Minimize distance/time with Gini constraint | | Route output | Single “optimal” route per vehicle | Set of routes with balanced segment inequality | | Metric exposed | ETA, distance, traffic | + Gini score (0=perfect equality, 1=max inequality) | | User control | None on fairness | Slider: speed vs. equality (Gini threshold) |
Recommended for fleets >10 vehicles with driver retention challenges. Not recommended for time-critical (medical, perishables) or single-vehicle operations. Appendix available: Gini coefficient calculation method used by SpeedNavi (Lorenz curve over leg durations, not distances).
Date: April 17, 2026 Subject: Impact Assessment of Integrating Gini Coefficient into SpeedNavi Routing & Distribution Logic 1. Executive Summary The SpeedNavi Gini Update introduces inequality measurement into route optimization. Traditionally, SpeedNavi focused on shortest-path or fastest-time algorithms. The new update leverages the Gini coefficient to evaluate and modify route suggestions based on how evenly travel distances, estimated arrival times, or workload are distributed across a fleet or multi-stop trip.
