When Sydney knows that a busy shopping and beach season is coming up they will put on extra buses, trams and ferries. Lots of them. Like 1200 extra trips per week this summer. The state government recognises that when places attract thousands public transport is key to making them work. And visitors appreciate the choice because they know that driving to busy places is a nightmare.
The problem is certainly not a shortage of them. The Victorian Department of Transport has 142 executives according to its annual report. With a median pay of $210k that's an executive wages bill north of $30m pa.
How many of that 142 do you think have (and use) discretion to add buses when demand calls?
Instead the opposite happened. Transdev, the bus operator, routed the 903 orbital SmartBus away from the very shops people would want to visit during the sales. People going to the sales had to transfer to a shuttle bus. Below is what they said on their website:
What should we do to make our network more robust and reliable so that it's useful on busy days when it should be the default mode of choice? After all many who don't otherwise take public transport will ride it to the football, the tennis, the races or the show. Would it not also be reasonable for it to have a similar role on other occasions where movement fails if too many people drive?
Here are four possible steps to improvement:
1. Split the SmartBus orbitals for improved network robustness
Our long orbital bus routes permit long trips to be made without changing buses. However that comes at a cost. I’ve often mentioned how orbital SmartBuses can have catchments that vary from apartments to semi-rural. The effect of having a single frequency for the whole route is that dense areas have too little service and sparse areas receive too much. Another issue is that a traffic snarl on one side of town can have knock on reliability effects on the other.
Shortening very long routes, starting with splitting the SmartBus orbitals into two to four segments, allows optimisation of service levels and isolating delays to only the section affected. Confining delays reduces the effect of traffic problems and speeds the timetable’s recovery from them. And better allocating service kilometres allows improved frequency where the people are. This is beneficial during busy times, even if no extra seasonal trips are added.
The orbital most affected by traffic around shopping centres is the 903 since it serves Essendon Fields DFO, Northland, Doncaster Shoppingtown and Chadstone to name a few. Two of those centres were skipped by the 903 on Friday as noted before. A 903 orbital split proposal with some wider benefits is discussed here.
2. Upgrade service frequency where justified throughout the year
I’ve previously looked at bus routes that, because of their high usage, need service upgrades (examples here, here, here and here). They tend to fall into two categories; those with fairly dense migrant-rich bus-using residential catchments (eg Tarneit, Sunshine, Springvale and Craigieburn) and those serving major shopping centres and universities (notably in the Box Hill – Monash – Chadstone area). The busiest routes tend to have a bit of both.
Patronage on major shopping centre routes, particularly on weekends, is high even when there are no special sales. Boardings per service hour can be two to four times higher than for regular bus routes. Especially on weekends busy routes such as the 733 and 900 justify frequency upgrades from every 30 – 60 minutes to every 10 – 20 minutes. Chadstone's main highway bus from Dandenong, the 800 past the premier's electorate office, runs only every two hours on Saturday afternoons and not at all on Sunday. Meanwhile Route 468, Highpoint's bus connection to Essendon and the Craigieburn line, is only every 40 minutes on Saturday and nothing on Sunday. 788 on the Mornington Peninsula also needs an upgrade though, in one of its few bus service initiatives, the 2020 state budget will deliver one by 2022.
High frequencies put more buses on the road. This relieves crowding, lessens long waits and makes services more robust in the event of delays (almost entirely due to car traffic). Costs can be reduced if we simplify networks as discussed most Fridays in Useful Networks. But easy ways for buses to move is also required as you'll see next.
3. Add bus priority on congested sections
A bus system becomes operationally unworkable and unattractive for passengers to use if traffic delays buses so they can’t keep to timetables. Extra ‘fat’ could be put into schedules but this costs extra vehicles to maintain a specified frequency and means waiting at time-points when roads are quiet. And buses become incredibly slow, especially when waiting and connection times are added, with overall end-to-end travel speeds often in the 15 to 20 km/h range.
The gold-standard form of bus priority is a dedicated way that gives buses a free run, uninterrupted by other traffic. Melbourne is big enough for these to be considered around key hubs including major shopping centres. Several ‘bus wormhole’ ideas are outlined here. If they had complete separation, buses could have provided the high capacity transport that centres like Chadstone need rather than be crowded out by cars on days when they are most needed.
A level below that is dedicated lanes on roads. However they are only justified where bus frequency is very high. Where this is not so and bus lanes appear almost empty to drivers the political pressure to remove them becomes overwhelming (as happened on Stud Rd whose main bus route, the 901, runs only every 15 minutes, even in peak times).
More modest measures include short queue jump lanes, signal priority at intersections and temporary traffic management during peak times (including events like sales) at pinch points. These can be highly cost-effective in areas where there are many bus movements, such as around shopping centres. However it is again best that the bus network has been made simpler and more frequent. And there needs to be planning and staffing, which gets us onto the next point.
4. Treat seasonal events that attract large crowds such as large sales and holiday seasons as major events with important transport needs
Such serious treatment includes events having their own transport plans. These should be drawn up months in advance with stakeholders such as bus operators, shopping centres and local government. These plans could cover matters such as information for passengers, altered access and parking arrangements for drivers, traffic management including active bus priority, mode shift and extra services where required. The emphasis should be on making public transport an enabler of improved access rather than a passive victim of gridlock.
Because we’ve been weak at network reform and aligning service levels to need, Melbourne’s bus network is especially fragile when it comes under pressure from increased patronage or car traffic. Its low profile and poor reputation also means that its potential role as an enabler of access and movement is either disregarded or ignored by departments and governments who should know better.
Points 1 to 3 above seek to make the bus network more useful and robust at all times, not just during special events. Point 4 ensures that events that generate surrounding area traffic have a transport plan that embraces rather than stymies public transport access. Following these points would put buses in a better position to contribute to the overall transport effort for everyone’s benefit.

You are correct Peter, major increases in frequency are needed for our bus routes, particularly on weekends and in off peak times. This coupled with increased services for special events would benefit passengers and encourage a patronage shift from cars.
