Routing Constraints (Vehicle Type, Weather)

Vehicle constraints include size, weight, fuel type, and restrictions like bridge clearances or hazmat rules. For example, a semi-truck may avoid tunnels or steep grades, while an electric car might prioritize routes with charging stations. RVs, buses, and emergency vehicles all have unique routing profiles.

Weather constraints adjust routes based on real-time or forecasted hazards. High winds can close bridges, and snow can shut down mountain passes. By applying weather data, systems prevent travelers from entering unsafe or impassable areas.

Combining both constraint types produces a highly personalized routing experience. A small car may take narrow backroads, while a heavy truck sticks to reinforced highways. In dangerous conditions, the algorithm automatically prefers safer corridors even if they take longer.

Routing constraints remind us that navigation is not one-size-fits-all—it’s dynamic, adapting to both the traveler and the world around them.
