Scooter Routing

Scooter routing provides route calculation using car roads with scooter-specific speed estimations. This type of routing can be performed online or offline.

In order to perform offline scooter routing, you have to download or prefetch optional data group NMAMapDataGroupScooterAttributes such as in the example below. For more information about Data Groups refer to Map Package Download.

// Select additional data group needed for offline scooter routing
[[NMAMapLoader sharedMapLoader] selectDataGroup:NMAMapDataGroupScooterAttributes];
// Whether download map package(s)
[[NMAMapLoader sharedMapLoader] installMapPackages:@[package]];
// Or prefetch
[[NMAMapDataPrefetcher sharedMapDataPrefetcher] fetchMapDataForBoundingBox:boudingBox error:nil];

Figure 1. Scooter Route

Scooter routing includes car-only roads. Since scooters are not permitted on highways, highways are avoided for this type of route calculation. In cases when forbidden, car-specific roads or highways cannot be avoided, the scooter routing computation fails.

This feature supports the speed limitation for scooters, which is 45 km/h. Calculated routes take into account the fact that the possible travel speed for scooters is slower than car travel, such as on roads where car travel speed is greater than 45 km/h. In addition, heavy traffic affects scooter travel time less than car travel time.

To calculate a scooter route, use similar steps as for other transport mode types, such as the following example:

// Create a NMACoreRouter
NMACoreRouter* coreRouter = [[NMACoreRouter alloc] init];
NMAGeoCoordinates* geoCoord1 =
  [[NMAGeoCoordinates alloc] initWithLatitude:49.276271 longitude:-123.113224];
NMAGeoCoordinates* geoCoord2 =
  [[NMAGeoCoordinates alloc] initWithLatitude:49.1947289 longitude:-123.1762924];

NMAWaypoint* waypoint1 = [[NMAWaypoint alloc] initWithGeoCoordinates:geoCoord1];
NMAWaypoint* waypoint2 = [[NMAWaypoint alloc] initWithGeoCoordinates:geoCoord2];
NSMutableArray* stops = [[NSMutableArray alloc] initWithCapacity:4];
[stops addObject:waypoint1];
[stops addObject:waypoint2];

NMARoutingMode* routingMode = [[NMARoutingMode alloc]
  initWithRoutingType:NMARoutingTypeFastest
  transportMode:NMATransportModeScooter
  routingOptions:0];

[coreRouter calculateRouteWithStops:stops routingMode:routingMode
  completionBlock:^(NMARouteResult *routeResult, NMARoutingError error) {
    // If the route was calculated successfully
    if (!error && routeResult && routeResult.routes.count > 0) {
      NMARoute* scooterRoute = [routeResult.routes objectAtIndex:0];
      // ...
    } else if (error) {
      // Display a message indicating route calculation failure
    }
  }];
