Automated Rapid Transit

    What do you guys think of this idea, the automated rapid transit system, sort of like a Luas system without the tracks and overhead lines, runs on its own segregated traffic lane (just like a bus lane)

    It is seen as a cost effective transport solution for smaller sized cities that would benefit from a light rail system but without the substantial construction costs, would be an ideal solution for cities like Cork, Galway or even parts of Dublin where Luas is not really financially viable.

    Self driving cars will render all current public transport obsolete imo

    And those who cannot afford self driving cars will need some form of public transport

    It's also a very inefficient use of road space

    Are you talking about self driving cars or busses?

    You wouldn't need to own one.

    They could utilize the whole road network removing completely traffic jams and traffic lights. Also there would no longer be a need for driveways and car parks thereby allowing more space for housing.

    . . . . Where are the self driving cars going to park when not in use/ charging?
    . . . Are people going to insist on having their own, single occupant uber for their morning/evening commute? So very little road space saving..
    . . . . How many like their own car? With their stuff in it... And will want to continue using it...
    . . . . I reckon there'll be fleets of uber style minibuses doing the local commuter runs, dropping to schools and to mass public transport..

    You could have charging stations/carparks outside the cities. They would not need to park in the city as once they drop someone off they would move onto the next person or if not required retreat to a holding area.

    Disallow it. Insist on multi occupancy.

    Sam as above but this would seem to be the same issue currently with public transport.

    Public transport in Ireland does not work. It is too expensive and inefficient. The autonomous car would utilise a resource already in existence (road) and eliminate the human (expense/strikes/sickies). With a grid a citywide operating system the efficiency would be outstanding.
    A world where you are collected at your door and dropped to the door of your office. No 15 minute walk to DART station/looking for a parking space clogging up city/figuring out bus connections.

    They really don't

    PT does work and people will use it if it's designed properly and is efficient to use. Luas proves this, as does every other city with a functioning mass transit system. The bus network here doesn't work because no thought goes into it and it has to compete for space with private vehicles. Reducing priority for cars and increasing it for PT is the only way forward. Your idea of more of the same is ridiculous and will not decrease traffic.

    Expalin that one to us. Are self driving cars significantly smaller than a regular compact car? Ford Focus is prob the average size car in Ireland. 4 metres in length give or take. What length will the average self driving vehicle be?

    Could be smaller, could be bigger. That is irrelevant.
    They can use all of the road so lanes can be narrower (if even required)
    They can be routed here there and everywhere to avoid congestion.
    They don't require traffic lights.
    They don't have to park.
    1 car can be used for multiple people.
    They would be more similar to a bus service rather than a traditional car with the difference being that they do not need to follow bus routes and go where people want to go rather than where the route is able to go.

    It is essentially a merger between public transport and private.

    Pawwed Rig, self driving cars will certainly be a revolution in transport and will have a massive effect on public transport.

    However it is also true that there simply isn't the road space in core city centers for normal sized self driving cars.

    Single seat self driving cars may help with that, however it will still take up a lot more space then people packed shoulder to shoulder and on two levels on a bus.

    I suspect in future, our core city centers will continue to be dominated by self driving buses, trams and metros. But our suburbs will be dominated by self driving cars and that on demand self driving cars will take you from your house to the nearest Metro/DART/Luas/Bus station and you will then take those into the core city at peak times.

    They will need to share the road space with cyclists, buses and trams.

    Most people want to go to the city center and there are a limited number of routes, so pretty irrelevant. You will still have lots of congestion. But at least you can work/read while sitting in the congestion.

    Well you will still need traffic lights for pedestrians and cyclists safety.

    They will need to park and charge up somewhere. Yes it doesn't have to be the city center, which is an advantage, but it will mean even more vehicle movments now going in two directions.
    Pawwed Rig wrote: »

    It will help a little, but the problem is that most people want to use it at the same time to go to much the same place. 8 to 9 am to work.

    You are correct that a lot of the above will help, but not as much as you think and I believe we will still have horrible congestion in the cities even with these and that we will still be relying on self driving trains/buses/etc.

    Is the basic suggestion a variation on the BRT (Bus Rapid Transport), but without the driver?

    Should work, but I think driverless Metro, and driverless Dart would be an easier step (Unions permitting).

    Similar idea yes, the driverless metro or dart would be a better step no doubt but the ART Trams are mostly designed for smaller cities where it would not be cost effective to construct a metro or even light rail system

    The title reminded me of Bombardier's Automated Rapid Transit ART300, the Innovia metro as they call it now.

    maxresdefault.jpg

    It's a light-to-mid sized automated metro, in use in Vancouver, Kuala Lumpur, and a few airport's like JFK in New York. This seems like the perfect vehicle for Metro North to me. Whilst it's not as large as most metro trains, it has more internal space than trams. It's fully automated, and can be driven by either rotary motors or linear induction motors, to allow it climb steeper gradients.

    Going back to what this thread is about, I don't see much difference between BRT and the system in the video. Articulated busses with 3 sections already exist.


  • Moderators, Science, Health & Environment Moderators Posts: 17,073 Mod ✭✭✭✭ Sam Russell


    I think the London Docklands Light Railway system would suit Dublin. It is automated, cheaply built and all overground (but soon to go underground).

    It uses two car sets connected internally that run as a four car set. It is now a quite extensive network and has plans to extend beyond its current area.

    It started small and built out as it was successful, and redefined itself as it built on that success.
