| Footage description: | Film shots of Godalming High Street, Roy Nelson introduces the programme. He points out the traffic congestion and explains that a by-pass has been proposed to ease the congestion. Gareth Jones,the consultant who was taken on by the council to work out a predicted traffic flow once a by-pass was built, explains how he set about his task. Aerial photographs and maps of Godalming are shown at intervals. Roy Nelson uses a rope model to model a simple network problem - how to find the shortest distance between two points in a network. Richard Scott goes on to show how one would go about modelling such a problem mathematically. Several still graphic aids are used. Pointing to a graphics board, Roy Nelson explains how one represents maximum capacity in a mathematical model of a traffic network. Richard Scott modifies the algorithms used to generate the traffic model to take into account costs of journeys. He uses a still graphics board to illustrate his points. While calculating a minimum cost journey through the network. Gareth Jones, the consultant who worked on the Godalming study, discusses the model developed in this programme, particularly in relation to the techniques used in his own model of Godalming traffic flow. Roy Nelson briefly summarises the programme. |
