Referencing
SmartOpenHamburg distinguishes between agents (acting individuals) and entities (usable objects) within the simulation. Both can be initialized using files (see Agent Configuration).
Entities are initialized by an EntityManagerthat has a data source (e.g. a csv-file like car.csv). While every agent is unique, there may be multiple entities with the same initialization.
The following example displays a car.csv. It defines values for relevant attributes of the Car. Every instance of a car is initialized by referencing the type column. All cars of type Golf have for instance a maxSpeed of 13.89 m/s.
| type | maxAcceleration | maxDeceleration | maxSpeed | length | height | width | trafficCode | passengerCapacity | velocity | mass |
|---|---|---|---|---|---|---|---|---|---|---|
| Golf | 0.73 | 1.67 | 13.89 | 4.5 | 2 | 2 | german | 4 | 0 | 1500 |
The properties are further described below.
| property | description |
|---|---|
| type | Identification column |
| maxAcceleration | Acceleration module parameter in meter/second² |
| maxDeceleration | Acceleration module parameter in meter/second² |
| maxSpeed | Acceleration module parameter in meter/second |
| length | Dimension parameter for occupancy on the road in meter |
| height | Dimension parameter for occupancy on the road in meter |
| width | Dimension parameter for occupancy on the road in meter |
| trafficCode | Identifies the behavior on intersections without traffic lights |
| passengerCapacity | The amount of passenger that can be driven by the car beside the driver |
| velocity | The starting velocity in meter/second |
| mass | Might be used by the acceleration module but is not right now. Unit in kilogram |
As by now the model includes the following entity types:
- Car
- Bicycle
- Ferry
