The official and industry enthusiasm for "one size fits all" little buses with only two doors and a high floor (and no more artics) comes home to roost. When is somebody going to wake up? The B Line double deckers have little advantage being so slow and with long headways resulting in quite low route capacity. One day I think that a metro line to the northern beaches will be added to the list of future projects.'Crush capacity' warning for buses to Sydney's northern beaches
August 13, 2019 — 12.00am
Sydney commuters will have to endure a far greater number of crowded buses on many routes within the next decade, especially those to the northern beaches which will be in danger of easily hitting "crush capacity".
The warning comes in Infrastructure Australia's latest report card, which confirmed Sydney's public transport has become more crowded over the past two years.
The nation's top infrastructure adviser forecasts substantial growth in demand for public transport in Sydney over the next 12 years as more people opt for trains and buses due to congested roads, rising parking costs, and more apartments built along rail lines.
Sydney's bus services are predicted to become more crowded.
And it predicts trains to the city's west and south west will become more crowded by 2031.
Bus priority lanes along the congested Military, Spit and Pittwater roads on the north shore are forecast to result in commuters opting for buses such as the B-line services to get to and from work.
"As a result, services using the northern beaches bus corridor are forecast to be operating well in excess of crush capacity all the way from Dee Why to North Sydney in 2031," the report warns.
A standard 45-seat bus is deemed to reach crush capacity when it is carrying 60 passengers.
Passenger demand for buses travelling along busy Victoria Road, as well as the bus-only T-way route from Parramatta to Liverpool, is expected to rise for similar reasons.
"Bus priority measures on these routes mean that they are forecast to offer proportionately faster travel, relative to worsening conditions for driving," the report said.
With Sydney's population forecast to grow from 4.9 million to 6.4 million by 2031, the independent infrastructure body makes the case for further investment by the federal and state governments in the transport network.
Green Square station is under increasing pressure from a population surge in surrounding suburbs.
Sydney has eight of the 10 most congested roads in Australia during the morning peak, the worst of which is a stretch of the Gore Hill and Warringah freeways.
On the rail network, the T8 Airport Line between the fast-growing precincts of Green Square and Mascot in Sydney's south, and a stretch of the same line from Revesby to Panania, is one of the "most challenged by demand growth".
The T2 Inner West line, and the T5 Cumberland between Merrylands and Parramatta, are also at risk of operating above "crush capacity" by 2031. On trains, crush capacity is defined as six people standing for every 10 seated.
Infrastructure Australia predicts new metro train services, such as the $12 billion line from Chatswood, under Sydney Harbour to the CBD and beyond, will reduce the likelihood of crowding on trains through the north shore and Bankstown rail corridors.
While commuters can expect it to become harder to find a seat on trains by 2031, the opening of several metro lines over the next decade means few of Sydney's train lines are forecast to be operating above "crush capacity".
Standing in carriages will become more common for commuters because the metro trains have fewer seats than Sydney's double-deck trains. However, the report said the greater frequency of metro trains meant they would be less crowded.
The state government expects to start construction on a $20 billion metro line from Sydney's CBD to Westmead near Parramatta next year, and complete a metro line from St Marys to the new $5 billion Western Sydney Airport at Badgerys Creek by 2026.
At least it looks like completion of the intial metro projects will substantially ease the crush capacity pressures on the Sydney rail network. As for street public transport, unless they make a major move to buy lots of artics, we will have to keep plugging away for more tram projects.
