This definitely should be an option looked at. One small point. Bus lanes do require pavement reconstruction. The bus lane in Grenfell and Currie is slways developing ruts and being resurfaced. Electric buses have higher axle loads, so I can't see anything less than new concrete construction being practical. The cost difference is the cost of adding a couple of rails. However, that is minor.ml69 wrote: ↑Thu Sep 26, 2024 9:55 amThis is a really good point. Trams have limited benefit for those people who don’t live near the line.Saltwater wrote: ↑Tue Sep 24, 2024 4:57 pmWell most of the inner city infill zones are along existing PT corridors (buses), so at least there's that.
The argument with trams is great for those that live or work along the line, but take Henley Beach Road for example, where you can't just remove a lane for trams without significantly impacting traffic flow. And most of that traffic isn't going anywhere when people still need to travel to or from areas the trams don't serve, like Lockleys, Fulham Gardens etc...
In my opinion, for the key east-west commuter route, a BRT system is better. It will have many of the benefits that the Obahn system has, which is Adelaide’s most popular public transport route. I know this won’t be popular opinion on this forum - hear me out on this.
Proposal:
- A continuous bus lane starting corner of Seaview Rd West Beach (running along Burbridge Rd, Sir Donald Bradman Dr) to West Tce in the CBD. From West Tce, buses join mixed traffic and turn right onto the bus lanes on Currie/Grenfell. At East Tce, turn onto Bartels Rd where a continuous bus lane recommences and terminates at Uni SA Magill (via Flinders St Kent Town, The Parade, Penfold Rd).
- Why SDB Drive rather than Henley Beach Rd? 1) Faster. 2) Opportunity for Airport Express bus to use the same BRT lane. 3) Opportunity to build park n ride facilities near Vimy Ave (on airport land) and opposite West Beach Apex Park on Burbridge Rd. We’ve seen how popular park n rides are on the Obahn.
- New fleet of modern (European?) 100% electric articulated buses, similar to those being used on the Brisbane Metro busway.
- New high-quality bus shelters, more like the tram stops we have in the CBD. Increased spacing between bus stops to 500-700m spacing.
- Traffic light priority at all signalised intersections.
Benefits:
1. Very inexpensive when compared to a tram. Also much faster implementation and less disruption during construction (main disruption probably involves widening some signalised intersections).
2. The biggest benefit is FLEXIBILITY. The BRT lane can be used by other buses originating from outside the BRT route itself. Eg buses from Henley Beach, Fulham Gardens, Harbourtown, Rostrevor etc can utilise the BRT lane for speedy ride into the CBD. In fact, these other bus routes could operate express on the BRT lane. Again, this is similar to the Obahn which collects passengers from various outer suburbs and then delivers them rapidly into the CBD. Trams don’t have this flexibility.
3. Electric bus is same speed as a tram. Both will have signalised priority at traffic lights.
4. Allows the option for BRT lane to be potentially used as normal traffic lanes during the evening (7pm to 7am).
I'd also say that your proposal also means trolleybuses could be employed...especially European hybrids that can go off grid for diversions and route extensions.
Having said all that, it's not either/or. There's no reason why a bus cannot share a dedicated lane with trams. Not only do tram/bus shared lanes exist in Europe, but trams, buses, cars, bikes have shared roads since trams and buses existed.
So, why not both? There's no reason in the world why buses and trams couldn't share a dedicated public transport lane any more than they already share road spaces round the world now. (I've often said here that Port Road and Grange Road buses could share the tram line along Port Road from West Terrace to Hindmarsh. That would save passengers a lot of time, AND get buses out of the way of cars there. Win win?.
