Fleet telematics, odometric calculation, dashboard UI/UX, predictive logistics, KM analytics. 1. Introduction The transportation and logistics sector relies heavily on accurate distance measurement for cost allocation, regulatory compliance (e.g., tachograph laws), and vehicle lifecycle management. The "Calculadora KM" (Kilometer Calculator) series of tools has emerged as a niche solution for small-to-medium fleet operators. The latest iteration, Painel Dash Tool v 2.2 , claims to unify raw odometric data with interactive dashboard visualizations.

Author: Institute of Logistics & Telematics Research Publication Date: April 2026 Version Analysis: 2.2 Abstract In the context of modern fleet management, the accurate calculation of kilometer-based metrics (fuel efficiency, maintenance windows, and driver performance) is critical. This paper presents an evaluation of the Calculadora KM Painel Dash Tool v 2.2 , a specialized dashboard application designed for real-time odometric analysis. We examine its core algorithmic improvements, user interface (UI) enhancements, and integration capabilities compared to its predecessor (v 2.1). Findings indicate that version 2.2 introduces a 22% faster data processing latency and a novel predictive maintenance module using historical kilometer deviation patterns. Limitations regarding API scalability are also discussed. This paper presents an evaluation of the Calculadora
