Light Rail or Automatic Guided Transit
The quality and attractiveness of urban public transport has been improved by several technological innovations over the past twenty years. Operating conditions have been transformed, with improved safety and flexibility; adaptation to the needs of passengers and operators can be ensured owing to the possibilities offered by automation. Light rail and automatic guided transit systems present intermediate characteristics between those of buses riding on shared right of way and those of conventional metros on segregated right of way, from the point of view of investment costs. In this paper, the two types of new transit systems operated in France for more than ten years: LRT and AGT are presented.
