THE COMPUTER AS A FOCAL POINT FOR HIGHWAY DESIGN. SINO-BRITISH HIGHWAYS AND URBAN TRAFFIC CONFERENCE. PAPERS PRESENTED AT THE CONFERENCE HELD IN BEIJING 17TH-22ND NOVEMBER 1986

This paper outlines the use of the moss computer modelling system, developed by ws atkins & partners, for the design of roads. It describes the 14 stages in the development of a geometrical design of a highway scheme, using the system. The following features can be modelled in the moss system as part of the complete design process: (1) utilities, including pipes and cables; (2) drainage; (3) lighting; (4) communications; (5) fences; (6) road markings; (7) road signs; (8) structures. Examples of projects which have used the system are then discussed, with particular reference to the principal benefits for each application; (1) the cameroun highway; (2) mirgab transportation centre and approach roads, Kuwait; (3) London docklands light railway; (4) the M20 motorway. The authors conclude that the Moss modelling method, together with its applications, demonstrates a logical, economical, and quality-assured approach to road and railway design, because (1) it allows the design to proceed in a logical sequence; (2) it is economical, because it provides a single store for all project data and human input is minimised; (3) the quality of its design is assured in several ways.
