CalculateIsolinesRequest

Enables special road types or features that should be considered for routing even if they might be restricted by default for the selected travel mode. These include high-occupancy vehicle and toll lanes.

Determine areas from which Destination can be reached by this time, taking into account predicted traffic conditions and working backward to account for congestion patterns. This attribute cannot be used together with DepartureTime or DepartNow. Specified as an ISO-8601 timestamp with timezone offset.

Specifies road types, features, or areas to avoid (if possible) when calculating reachable areas. These are treated as preferences rather than strict constraints—if a route cannot be calculated without using an avoided feature, that avoidance preference may be ignored.

When true, uses the current time as the departure time and takes current traffic conditions into account. This attribute cannot be used together with DepartureTime or ArrivalTime.

Determine areas that can be reached when departing at this time, taking into account predicted traffic conditions. This attribute cannot be used together with ArrivalTime or DepartNow. Specified as an ISO-8601 timestamp with timezone offset.

An optional destination point, specified as [longitude, latitude] coordinates. When provided, the service calculates areas from which this destination can be reached within the specified thresholds. This reverses the usual isoline calculation to show areas that could reach your location, rather than areas you could reach from your location. Either Origin or Destination must be provided.

Options that control how the destination point is matched to the road network and how routes can approach it. These options help improve travel time accuracy by accounting for real-world access to the destination.

The format of the returned IsolineGeometry.

Controls the detail level of the generated isolines. Higher granularity produces smoother shapes but requires more processing time and results in larger responses.

An Amazon Location Service API Key with access to this action. If omitted, the request must be signed using Signature Version 4.

Controls the trade-off between calculation speed and isoline precision. Choose FastCalculation for quicker results with less detail, AccurateCalculation for more precise results, or BalancedCalculation for a middle ground.

Determines whether routes prioritize shortest travel time (FastestRoute) or shortest physical distance (ShortestRoute) when calculating reachable areas.

The starting point for isoline calculations, specified as [longitude, latitude] coordinates. For example, this could be a store location, service center, or any point from which you want to calculate reachable areas. Either Origin or Destination must be provided.

Options that control how the origin point is matched to the road network and how routes can depart from it. These options help improve travel time accuracy by accounting for real-world access from the origin.

The distance or time thresholds used to determine reachable areas. You can specify up to five thresholds (which all must be the same type) to calculate multiple isolines in a single request. For example, to determine the areas that are reachable within 10 and 20 minutes of the origin, specify time thresholds of 600 and 1200 seconds.

Configures how real-time and historical traffic data affects isoline calculations. Traffic patterns can significantly impact reachable areas, especially during peak hours.

The mode of transportation to use for calculations. This affects which road types or features can be used, estimated speed, and the traffic levels that are applied.

Additional attributes that refine how reachable areas are calculated based on specific vehicle characteristics. These options help produce more accurate results by accounting for real-world constraints and capabilities.
