Package org.opentrafficsim.road.od

Class OdMatrix

java.lang.Object
org.opentrafficsim.road.od.OdMatrix
All Implemented Interfaces:
Serializable, org.djutils.base.Identifiable
public class OdMatrix extends Object implements Serializable, org.djutils.base.Identifiable
The minimal OD matrix has 1 origin, 1 destination and 1 time period. More of each can be used. Further categorization of data is possible, i.e. for origin O to destination D, for lane L, for route R and for vehicle class C, the demand at time T is D. The further categorization is defined by an array of Class's that define the categorization.
