Punnett – THE DEVELOPMENT OF PUBLIC TRANSPIORT INFORMATION SYSTEMS AND THE APPLICATION OF MODERN TECHNOLOGY 1981

Description

The paper reviews the evolution and current state (circa 1980) of public transport information systems, emphasizing British experience. Printed timetables remain fundamental but are often confusing or inaccessible; computerisation has begun to streamline production and supply databases for enquiry services. Other printed materials include fare tables, route maps and station displays. Spoken information—face-to-face, public address, telephone services and computer-generated voices—has expanded, with real-time systems (e.g. ERICA) improving accuracy by using live vehicle position data. Mechanical displays evolved from fixed signs and roller blinds to multi‑flap indicators; these reduced labor but retained limitations. The “information revolution” introduced electronic solutions: LED/LCD matrices, dot‑matrix boards, television monitors, centralized microcomputer control, and remote Viewdata/Prestel services, enabling interactive and distributed access. On‑vehicle displays are emerging but adoption is limited by cost. The author predicts wider videotext, satellite and automated transaction services, noting financial and usability barriers and posing questions about how better information will affect travel behavior and cost‑effectiveness.
