Intercity Transport Capacity

It has become general practice to specify, by way of design standards, certain fixed values for the maximum traffic volume N at a route or terminal during a busy day or hour. These standards do not explicitly include the occupation time b of the route or terminal. One might therefore think of using the maximum traffic load Nb in a busy period. Such a standard would, however, be independent of the number of channels n (area) in use. The ratio of traffic load and the number of channels might then beused, the utilisation or service level Nb/n.1
