RaceLineCalc: Track Analyzer

RaceLineCalc calculates a racing line from your own track image, map, plan, sketch, or satellite screenshot. Use track analysis to study apex placement, cornering, braking points, speed, and lap time. Create a track project: • Import an image and calibrate it with a known real-world distance. • Trace the left and right track boundaries and place the start/finish reference. • Choose a point-based, car-based, or motorcycle-based model and a vehicle preset. • Run the calculation on your device. Review the result: • Calculated racing line and lap time. • Speed, longitudinal acceleration, lateral acceleration, and braking points. • Calculation stations, source boundaries, and generated track geometry. • Run history and comparison of compatible results on the same track. The point-based model quickly calculates a stable racing line. Car and motorcycle models add vehicle mass, power, grip, braking, dimensions, steering, and lean-related parameters. Presets cover karting, road cars, track cars, and motorcycles, while advanced controls allow deeper experiments. RaceLineCalc is local-first: the calculation runs on the device, and the core project flow does not require an account or upload your track project to a RaceLineCalc server. Model scope: RaceLineCalc calculates on a calibrated flat 2D track model. Elevation, banking, jumps, ruts, changing grip, weather, traffic, live surface conditions, and other real-world factors remain outside the current model. Always combine the calculation with real track knowledge and safe driving or riding practices. RaceLineCalc combines a racing line calculator, track analyzer, lap time calculator, and racing line optimizer in one local-first toolkit. As a practical race line calc, it uses calibrated track geometry and vehicle parameters to estimate the optimal line, speed profile, braking points, and lap time. Minimum-time trajectory optimization: RaceLineCalc solves a constrained minimum-time race trajectory problem on a calibrated flat 2D track. It combines track geometry with a point-based, car-based, or motorcycle-based model to calculate a minimum-time racing line, speed profile, braking points, longitudinal and lateral acceleration, and lap time. Use RaceLineCalc as a race trajectory optimizer, racing line calculator, lap time calculator, vehicle dynamics analysis tool, track analyzer, and trajectory planner. It supports image-based track analysis for karting circuits, indoor tracks, road courses, custom layouts, private test tracks, and local racing venues. The result is a time-optimized trajectory within the selected geometry, vehicle model, grip, power, braking, and configuration limits. Five physics models: point mass, Car V1 and V2, and Moto V1 and V2. Explore additional model-specific overlays and legends, then compare saved runs on the same track.
