IsolineAvoidanceOptions
Specifies features of the road network to avoid when calculating reachable areas. These preferences guide route calculations but may be overridden when no reasonable alternative exists. For example, if avoiding toll roads would make an area unreachable, toll roads may still be used.
Avoidance options include physical features (like ferries and tunnels), road characteristics (like dirt roads and highways), and regulated areas (like congestion zones). They can be combined to match specific routing needs, such as avoiding both toll roads and ferries.

Properties
Specifies geographic areas to avoid where possible. Routes may still pass through these areas if no reasonable alternative exists.
Indicates a preference to avoid car shuttle trains (auto trains) where possible. These may still be included if no reasonable alternative route exists.
Indicates a preference to avoid controlled-access highways (such as interstate highways or motorways) where possible. If a viable route cannot be calculated using only local roads, controlled-access highways may still be included.
Indicates a preference to avoid roads that may be subject to seasonal closures where possible. These roads may still be included if no reasonable year-round alternative exists.
Indicates a preference to avoid roads that require electronic toll collection transponders where possible. These roads may still be included if no viable alternative route exists.
For truck travel modes, indicates specific road classification types in Sweden (BK1 through BK4) and Mexico (A2, A4, B2, B4, C, D, ET2, ET4) to avoid where possible. These road types may still be used if no reasonable alternative exists.
Indicates types of regulated zones (such as congestion pricing or environmental zones) to avoid where possible. Routes may still pass through these zones if no reasonable alternative exists.
