    I seen this on the news the other day.

    My boss 20 years ago said something like this would solve our transport problems and now Belfast have it.

    No need for costly rails and construction disruption etc etc.

    Looks good...is it not similar to BRT?

    It is BRT. Also the acceleration of the French system looks pretty poor

    If you were to BRT Dublin as proposed, the Vanhool Exquicity vehicle as procured by Geneva is powered by overhead wires, but has a reported 7km battery endurance. You could (more expensively than regular BRT) install these on the dual carriageway portions of routes (N11, N4, N3) and allow passage thru the CC with minimal emissions/visual pollution.

    The overhead propulsion would also greatly improve acceleration/traction on possible routes like the very hilly N4.

    AFAIK the NTA are well into planning BRT for Dublin...although I'd imagine it's year away yet..

    They're just buses. Nothing "alternative" about it. The driver just doesn't work as hard, and the steering is done by robots via infrastructure that isn't necessary when you have a driver that knows how to steer a bus.

    I think the difference with the automated systems (certainly the Chinese prototype I saw recently) is that you can have longer vehicles than a normal articulated bus as the rear sections steer themselves and follow the marked path. This makes it more tram-like and better able to handle bends.

    This is exactly what caught my eye about the system, all the wheels follow the same line in the road, like on rails.

    And then if you want to go faster you add rails. Reinventing the wheel yet again.

    Hello,

    It's an awful shame that we can't get Shane Ross (our Minister for Transport !) to pay a bit more attention to the stuff discussed in these threads, and a little less attention to things that are nothing to do with him such as what's going on in North Korea or whatever....

    Just imagine, a Minister for Transport that was focused on.... well eh, transport !

    Putting these BRTs on the roads, particularly along the N1, N4, N7 and N11, with park and ride locations being the only places they pull in until they reach their final destinations, seems like a great idea to me.

    Thanks,

    G.

    Nope, they are just a cheap idea. Surprising that FG aren't all over it though as they don't believe in spending money on public transport.

    I don't see why they wouldn't have a decent straight line speed, I wouldn't want an on-street tram to be cornering all that fast either unless the track has the correct camber.
    They would be the "pathfinders" of the transport network, if a route proves to be an outstanding success, then yes lay rails, if not change the route for little more than the cost of some road paint.

    Yet for some reason spend many many multiples fixing infrastructure capacity issues caused by? You guessed it, their underfunding in the first place

    Why design a transport solution that will mean a commuter has to go out of the way to use it? It'll need to be accessible to people without cars.

    Why design a transport solution that will mean a commuter has to go out of the way to use it? It'll need to be accessible to people without cars.

    First priority is get some of the cars off the busy national roads and motorways, ease a bit of presure on the volume of vehicles going into Dublin and some of the other cities.

    No reason why local communities couldn't be provided with feeder bus services to the part and ride stops, if needed. Bring back the old "imps" for such a purpose perhaps ?

    Thanks,

    Transporting people in Ice Cream vans Imps is really going to get motorists to leave their cars at home.

    I would support the OPs proposal instead could use something like the new Streetlites instead of the old Imps. Anyway they werent wheelchair accesible so they will never be brought back.

    I was referring to local services to bring people to the nearest park and ride facility, where they could like up with the BRT lines I suggested above.

    Thanks,

    Use the existing Dublin bus fleet to feed into the main brt trunk routes.
    A ticket can be bought via your smart phone to cover the whole journey.
    Make the brt routes fully separated from traffic using a mixture of qbc’s and short tunnel sections into the city center, so that journey times can be guaranteed. Look up Seattle brt.
    Build large p+r’s at the start of these rote’s which are easily accessible from the main national routes, eg p+r @ cellbridge with a dedicated off ramp from the n4, qbc all the way to hueston for brt, tunnel from hueston through cc with appropriate stops to allow commuters off. Use dual fuel busses to allow diesel free running underground.
    Install tracks in short tunnel sections to allow for possible rail upgrade in the future.
    A series of orbital brt’s along the main trunk routes (possibly 3) would allow passengers traveling from,for example cell bridge, get to park west industrial estate using the n4 brt plus orbital brt.
    Toll the national routes on the city side of the p+r to force people into the p+r to use the brt service.
    At all brt stations at least 3 other modes of transport should be offered, eg hueston brt stop: cycling station, taxi rank, Dublin bus feeder service, walking, Luas red line, national rail.
    Anyway I might be just dreaming, but that’s my plan!

    I like this idea. We should draft a letter and get signatures from interested people. This should be sent to the minister, and to the real person in power the head of the transport department in the civil service end of things.

    Irish Commuters don't like connections. You just seem to be presenting something that will take people to somewhere, that'll allow them to get another service to their destination. P+R's and City Centre is not it. City Centre is only a focal point on our transport because the majority of our services route through it.

    So do you want a private bus for every person going to work in Dublin?
    Irish people don’t like connections as they haven’t been introduced to connections!
    The most important part of the above plan is the orbital routes that will allow dispersal of commuters around the capital before they come near the city center. Yes it will involve changing brts, but so what, this is what happens in every major city in the world. The only other option is all commuters have their own personal vehicle to get them into work........oh wait that’s what’s causing the gridlock.

    Yeah seen that. It’s a rehash of
    https://www.nationaltransport.ie/bus-rapid-transit/
    I really hope brt gets built, but it has to be proper brt with dedicated, segregated qbc’s and non ticket entry etc etc. look to the South American and Asian (Jakarta) examples. Brilliant systems.

    Any connections that have ever been tried have been crap that's why expecting to wait for over an hour for a bus in the cold after already being on a DART, a train or a Luas. Give them a reliable, high frequency, quick, efficient, clean and comfortable bus service and they will want to use especially if it offers time savings over driving they will want to use it.

    We had the old DART feeders which weren't popular because they were infrequent and unreliable using buses that were nosiy, dirty and old. So it was not high quality public transport.

    I’m really not sure which way to petition those in power, but one thing I am sure of is that Shane Ross couldn’t give a monkeys if Dublin ground to a halt tomorrow he won’t do anything that rocks the boat as he’s in such a precarious position politically. It’s the head of transport in the civil service and people that develop the policy that we should be trying to influence, whoever they are. Shane Ross, and any minister for transport (unless they’re in a strong government) are only a smoke screen.

    That's not what i said.

    I live in Clondalkin and work in Leixlip. Public transport requires me to go into the city and out again. Getting to Liffey Valley takes longer.

    I accept a need for connections, but they should not be the core basis for a service. If it's going through arteries, it should be accessible at those points. it should not be setup, to require people to commute, to their commute.

    Yeah exactly. Imagine an articulated or bi articulated brt bus capable of carrying 300 people driving down the segregated qbc on the n4. The passengers have parked their cars in the new efficient p+r at cell bridge/leixlip and they all bought their “tickets” last night via an app. The brt bus makes one of its 4 stops at the first orbital loop somewhere near Palmerston, some passengers get off some continue on towards the cc knowing there are 2 more orbital loops before the last stop on the inner loop.
    At each orbital loop they have a brt service that can bring them on to another trunk brt Route that’s closer to their place of work, or they can walk, or cycle, as there are cycling stations, or get the Luas, or get local Dublin bus if that leaves them closer.
    All of this can be done through one ticketing app.
    This is what we should be aiming for.

    Agreed, which is why the orbital routes are so important. They allow you to get on the brt orbital loop that stops at the n7 and stops at the n4. You the hop off their and get the brt to the p+r in leixlip. You can the cycle or walk from there.
    However would your route not be going against peak traffic? You’d be leaving Dublin during rush hour to get to leixlip therefore traffic would be light when you clear clondalkin and get onto the n7 then go via outer ring road to n4?

    If you go via m50, the benefit to you if this system was introduced would be a lot less traffic on the motorways if you still insisted on driving.

    You are talking about ditching cars. So we should be basing this discussion on Public Transport options. I used mine to show that not only have I accepted not all public transport suits, I don't expect it to. There can be requirements to connect, but that should not be a fundemental design for bringing the service in.

    Such a link between N7 and N4 would not be a simple one, unless pushed out around Rathcoole or Newcastle. Nothing on the motorway changes with that. These aren't people trying to get into the city either.

    Connection would be the outer ring round, three lane carriage way that includes bus lane already that goes from kings wood to Lucan.

    The car needs to be ditched it has no place in a modern city when people are using it instead of viable transport options, all the car does is impede the flow of the viable transport options.
    The viable transport options must be built which in my mind is a proper brt system for all of dublin.
    In your case a car is worthwhile as your traveling away from Dublin during rush hour.

    I still think you are ignoring a big flaw to your proposed system. It is dependent people looking to get to the City Centre, or back out to the P+R's. That's not what people want to do in Dublin. The City Centre focus of public transport is a legacy design issue. Which is why you've so many driving around Dublin. They don't want to connect between multiple services to get around.

    Ok so are you saying a high percentage of people from satellite towns around Dublin, (swords, ashbourne, dunboyne, cellbridge, Naas, blessington, bray) want to travel across Dublin to get to industrial estates, eg parkwest, inchicore, Liffey valley, damastown, etc etc.
    I’m saying that if the above traffic can be funneled into brt’s, won’t this free up more road room?
    The way I see traffic in Dublin it’s a 2 problem situation.
    Number 1 is the traffic mentioned above and number 2 are the people from Dublin traveling around Dublin.

    I reckon an orbital BRT route on the m50 (using hard shoulder running where possible and segregated platforms and stops at every junction and overpass, combined with a transport hub (for buses, trains, coaches, bikes and park and rides at as many of the junctions as possible) and if possible get industrial estates/large employers to operate feeder buses to these...

    To reduce the traffic on the m 50 we have to reduce the amount of cars. We can only do this by reducing the amount of cars coming onto the m50 via the main arterial roads m1 n7 etc etc.
    we do this by funneling people into p+r’s and running top quality public transport out the other side of the p+r’s.
    If we used your proposal the problem is how would people from Naas, swords etc get to the orbital brt?
    There’s just no room at these junctions for large p+r’s. Plus navigating into the p+r’s at a main arterial junction would cause some people to have a breakdown!
    Glad you see the benefit of brt though.


  • Registered Users, Registered Users 2 Posts: 8,838 ✭✭✭Markcheese


    I agree with you on the cars, but how do we get there? I'd still do other BRT routes, and other public transport projects, like metro North, but I'd have stations/stops/interchanges where they cross the m50, naas coaches/buses could pull in at a red cow interchange to go to a different part of the route...
    A kind of spoke and hub set up, with the m50 as A rim... And each stop on the m50 rim as a mini/local hub...
    And it'd probably mean cpo ing sites for multistorey park n ride /bus/coach stations... As close to junctions as possible...

    I have to disagree the M50 IMO should be kept for cars it is a motorway at the end of the day. We should keep the M50 for cars as it is needed to keep the roads off the M50 inbound free of large amounts of car traffic. Your plan would require widening the M50 as hard shoulder running would not be practical as the hard shoulders are needed in case of emergency and for blue light vehicles.

    Here is a video I came across the other day, might offer a solution for the smaller towns and cities that can't justify a full tram system.


    The quality of the video is quite poor (all expense spared), but best to try to look beyond that.
    edit:
    Well let's forget the Chinese copy, here's an active system in use in France.


    I saw something similar in Metz.

    There is one problem with guided buses running on tarmac;

    where the wheels consistently run over the exact same inches of road surface, longitudinal grooves develop in the road.
    An example is outside Dun Laoghaire station, where the rutted surface is dangerous for cyclists.
    The only way to avoid this, is to place a heavy duty concrete bed a few inches under the tarmac.

    I know of quite a few motorway sections like that in the UK (may be fixed now), but the trucks could almost be driven hands free as the "tram lines" held the vehicles in the track.
    As they say, if it's worth doing, it's worth doing properly.

    And if you're going to have to put down a heavy concrete base might you be as well putting in rails and and running a tram.. 😀

    To reduce the traffic on the m 50 we have to reduce the amount of cars. We can only do this by reducing the amount of cars coming onto the m50 via the main arterial roads m1 n7 etc etc.
    we do this by funneling people into p+r’s and running top quality public transport out the other side of the p+r’s.
    If we used your proposal the problem is how would people from Naas, swords etc get to the orbital brt?
    There’s just no room at these junctions for large p+r’s. Plus navigating into the p+r’s at a main arterial junction would cause some people to have a breakdown!
    Glad you see the benefit of brt though.

    What is stopping us build above the m50? Or cpo if necessary ...

    Whatever about segregation, I really don't see why hard shoulders couldn't become bus lanes on some of our motorways and major arterial routes. The UK have them as driving lanes on some sections at some times of the day! It could be that we have them only as bus lane at peak times/ changable which is my experience of them in the UK.

    As for no demand for Park and Ride, speaking of the N11 a number of villages/ businesses have had to put in restricted and/or paid parking to stop commuters parking to get Bus Éireann, and I know capacity is also an issue in and out at peak times. Demand is there, capacity on the transport and for the parking isn't. Even around Foxrock and Stillorgan people park up to get the bus!

    I'll use the N11 as my example - hard shoulders to bus lanes, park and rides in Wicklow, Ashford, Newcastle/ NewtownMountkennedy, Kilpeddar (and Kilmac, but then it always should've had one and kept the 145 going that far!). Bus lane through Glen of the Downs through to Kilmacanogue would drastically reduce journey times for buses, and making it more attractive than the car. Link with Luas at Cherrywood (Sandyford link), and then on to the city centre. A Sandyford route would also be an option.

    Build what? P+r’s? But then you’d be bringing more traffic closer to the m50 junctions. The idea would be to reduce traffic further back on the system.

    Yeah this is what we should be thinking of. The qbc should run from these places into the cc, with interchanges in 5 areas to allow for orbital movements around the city. All the busses using the qbc should be part of a brt system.

    There's a world of difference between reinforcing a road bed with a concrete sub base and laying a trackbed and rails and all the other stuff that goes along with constructing a tram line.

    But there's also a world of difference in x amount of people carried on y buses and the 2x people carried on y trams. If we had the dosh, we'd be building trackbed where we're not digging tunnels for Metro.

    They should run a bus service on the Metro West route - inc building a dedicated bridge across Liffey.

    What was the metro west route?
