Unattended Metro Lines Offer Low Cost Services Adaptations Possibilities Regular full night public services operations Unforeseen or planned public services adaptation to occasional needs

摘要

Unmanned metro have shown since their beginnings that occasional or predetermined services adaptations are easily made to adapt the services to expected or in real time unexpected demand variations. Now the biggest metropolis have a growing development of night life, and several important night bus services have been created to provide adapted services, but with rather unattractive headways to keep the costs as low as possible. The aim of this paper is to emphasize the possibilities for new lines of urban unattended metro in great metropolis to offer at a relatively low cost regular full night services (24 hours/7 days) with headways attractive enough to be well adapted to the night life in big cities, but if - and only if - the necessary specifications are included in the very first RFP made for theses metro lines. Therefore a strong political vision with a realistic future insight will be necessary as soon as the need for new urban metro lines appears in order to be able to include these full night attractive services from the beginning in the project's specifications.
