Mobility glossary

  • break location - the start or end point of a route.
  • cost - fixed costs in seconds that are added to both the path cost and the estimated time.
  • costing model - set of costs for particular methods of travel, such as automobile or pedestrian.
  • edge - a line connected between nodes
  • factor - multiply the cost along an edge or road section in a way that influences the path to favor or avoid a particular attribute
  • graph - a set of edges connected by nodes used for building a route
  • location - a latitude, longitude coordinate pair, specified in decimal degrees that determines the routing and order of navigation.
  • maneuver - an operation to be performed during navigation, such as a turn, and the expected duration of the movement.
  • narration - textual guidance describing the maneuver to be performed, such as a turn, distance to travel, and expected time.
  • path - the sequence of edges forming a route
  • penalty - fixed costs in seconds that are only added to the path cost. Penalties can influence the route path determination but do not add to the estimated time along the path.
  • route - sequence of edges and maneuvers forming the best travel path between locations given the available road network, costs, influence factors, and other inputs.
  • short path - a route that attempts to minimize distance traveled over the constituent edges, but may not be the shortest distance.
  • through location - an optional location to influence the route to travel through that location.
  • tiled routing - method of building a path on graph data that has been split into square cells.
  • time - the number of seconds estimated to complete a maneuver or trip, including any additional costs.
  • trip - results of an entire route, including locations, legs, and maneuvers.
  • height - with respect to elevation, the height above or below sea level at a specific location (lat,lng).
  • height with range - computing the range (cumulative distance) and height for a series of lat,lng pairs of a line or shape. This is very useful for charting/graphing.
