<strong>D5</strong> <strong>Annex</strong> <strong>WP</strong> 3: DATABASE METHODOLOGY AND DATABASE USER MANUAL – FREIGHT TRANSPORT DEMAND<br />

Method variable V5<br />

V(n) – number of vehicles on the<br />

road link (n) of the TEN network<br />

Derived from traffic counts on the network<br />

(AADT) (for parts of the network)<br />

Trip generation and assignment model<br />

(passenger and freight)<br />

Method variable V6<br />

V l (n) ­ number of long distance<br />

vehicles on the road link (n) of the<br />

TEN network<br />

Trip generation and assignment model<br />

(passenger and freight)<br />

Method variable V7 l – distance category (long) The distance categories can be agreed<br />

(for example, long distance journey – exceeding<br />

300 km)<br />

Method variable V8 L ­ set of long distance OD relations NUTS2 zone combinations with a distance longer<br />

than the minimum threshold<br />

Method variable V9<br />

EU – total set of OD relations in the<br />

EU<br />

All NUTS2 zone combinations<br />

Remarks concerning method<br />

variable computation<br />

The same trip generation and assignment model can produce a complete variable set necessary to compute the indicator. This<br />

variable set can be split into variable set for passengers and variable set for freight.<br />

Model required to compute the<br />

method variables (listed above)<br />

Definition<br />

Trip generation and assignment model (passenger and freight)<br />

Model (component) analog<br />

For instance: VACLAV, SCENES, NEAC<br />

Model component C1 OD freight matrices (annual) annual number of freight vehicles that traveled between each OD<br />

pair, annual tons transported between each OD pair<br />
