Class ODMatrix

  • All Implemented Interfaces:
    Serializable, Identifiable
    public class ODMatrix
extends Object
implements Serializable, 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.
