NDD Transit SetTransit Set

Overview

A transit set provides a custom matrix of values between locations. Transit sets can be used to supply pre-computed distance or time matrices, or to define custom dimensional quantities for movements between locations. Transit sets are referenced by transit generators.

TransitSet

Schema definition

message TransitSet {
  repeated TransitValue transits = 1;
}

Fields

transits

A list of transit values defining the pairwise quantities between locations.

Transit Value

A transit value defines a single origin-destination pair and the associated quantity.

Schema definition

message TransitValue {
  required string fromId = 1;
  required string toId = 2;
  required float value = 3;
}

Fields

fromId

The identifier of the origin location.

toId

The identifier of the destination location.

value

The quantity for this origin-destination pair on the associated dimension.

Examples

transits { fromId: "loc-A" toId: "loc-B" value: 15.5 }
transits { fromId: "loc-B" toId: "loc-A" value: 16.2 }
transits { fromId: "loc-A" toId: "loc-C" value: 22.0 }
transits { fromId: "loc-C" toId: "loc-A" value: 21.8 }

Notes

• Transit values are directional. The value from A to B may differ from B to A.
• A transit set should contain values for all origin-destination pairs referenced in the model. Missing pairs will result in an error.
