Example 1 with TraverseModeSet

use of org.opentripplanner.routing.core.TraverseModeSet in project OpenTripPlanner by opentripplanner.

the class SIsochrone method getIsochrone.

/**
 * Calculates walksheds for a given location, based on time given to walk and the walk speed.
 *
 * Depending on the value for the "output" parameter (i.e. "POINTS", "SHED" or "EDGES"), a
 * different type of GeoJSON geometry is returned. If a SHED is requested, then a ConcaveHull
 * of the EDGES/roads is returned. If that fails, a ConvexHull will be returned.
 * <p>
 * The ConcaveHull parameter is set to 0.005 degrees. The offroad walkspeed is assumed to be
 * 0.83333 m/sec (= 3km/h) until a road is hit.
 * <p>
 * Note that the set of EDGES/roads returned as well as POINTS returned may contain duplicates.
 * If POINTS are requested, then not the end-points are returned at which the max time is
 * reached, but instead all the graph nodes/crossings that are within the time limits.
 * <p>
 * In case there is no road near by within the given time, then a circle for the walktime limit
 * is created and returned for the SHED parameter. Otherwise the edge with the direction
 * towards the closest road. Note that the circle is calculated in Euclidian 2D coordinates,
 * and distortions towards an ellipse will appear if it is transformed/projected to the user location.
 * <p>
 * An example request may look like this:
 * localhost:8080/otp-rest-servlet/ws/iso?layers=traveltime&styles=mask&batch=true&fromPlace=51.040193121307176
 * %2C-114.04471635818481&toPlace
 * =51.09098935%2C-113.95179705&time=2012-06-06T08%3A00%3A00&mode=WALK&maxWalkDistance=10000&walkSpeed=1.38&walkTime=10.7&output=EDGES
 * Though the first parameters (i) layer, (ii) styles and (iii) batch could be discarded.
 *
 * @param walkmins Maximum number of minutes to walk.
 * @param output Can be set to "POINTS", "SHED" or "EDGES" to return different types of GeoJSON
 *        geometry. SHED returns a ConcaveHull or ConvexHull of the edges/roads. POINTS returns
 *        all graph nodes that are within the time limit.
 * @return a JSON document containing geometries (either points, lineStrings or a polygon).
 * @throws Exception
