Roadnet​

Lane​

Lane is the basic unit of road net geometric elements. There are three types of lanes, driving lanes, walking lanes and rail transit lanes. Lane is a section of a road or junction.

Road​

Road is a traveled way on which people or wheeled vehicles move. In MOSS, road is composed of lanes, and one road can have multiple type of lanes.

Junction​

An area where two or more roads come together. One road can not directly connect to other lane, roads must be connected by lanes within junctions.

AOI (Area of Interest)​

AOIs are the buildings on the roadside which have a specific connection relationship with lane. People/vehicles can travel back and forth between AOI and the road network.

POI (Point of Interest)​

POI is specific locations that have some significance, it could be a landmark, business, or any other place that might be of interest to users. All POIs are contained in AOIs.

Trip​

Trips are the demand of mobility simulation. Trips describe the movement of people or vehicles from one location to another. The basic unit of trips is (who, when, where, how).

  • "Who" means the person or vehicle marked by ID.
  • "When" means the departure time of the trip.
  • "Where" means the destination of the trip.
  • "How" means the mode of the trip, including driving and walking now.
