This was contributed by a reader in response to the SNP’s alternative to trams:
“It isn’t the number of buses, routes nor their frequency that is the main problem in improving bus services in Edinburgh (and therefore attracting more passengers). None of these tackles the major remaining barriers to increasing passenger numbers, namely the ever-lengthening journey times. In fact, more services and increased frequencies actively conspire against making journey times faster – witness the oft-quoted number 22: its very success now means that travelling on the 22 takes longer, and is more crowded than ever. That route has reached maximum capacity. Putting even more buses on (of whatever service) will only make it worse.
To make bus travel better, much more attention must be paid to expanding and viciously enforcing parking restrictions, bus lanes and giving absolute priority to buses at junctions and traffic lights. On every route, each of the weak points must be addressed, for example in the case of the number 22 route, we need absolute bus priority at Elm Row and Picardy Place roundabouts, the Waterloo Place junction with Princes St as well as at the West End of Princes Street.
Across the city, instead of having bus lanes ending before a junction, there need to be separate bus traffic lights, for example. The SNP, in proposing merely more and somehow “better” buses, seriously fail to understand the problems faced by a bus network in an ever-more congested city centre and associated transport planning solutions. Around the world, cities face similar, often worse, problems than Edinburgh. We need to look there to learn from success and failure, rather than devising populist and ill-informed policies that any transport planner will tell you will deliver nothing like the results of a tram system.
If the SNP are serious in their commitment to expanding public transport use, and reduce car use, in Edinburgh based solely on buses, they must devise serious and drastic planning measures across the city and re-shape the balance between car and bus, together with the design of the street infrastructure. None of this is cheap, straightforward or even popular. And even then, the best they can hope for is a few percentage point increase in numbers and little in the way of serious non-bus traffic reduction, which has to be the aim of transport policy in a city with a fragile economy.
And one of the key lessons is that on heavily-used existing public transport corridors (such as Leith Walk/Princes St) there comes a point where the route reaches absolute saturation and no more can be done by buses alone. The very success of that corridor poses its greatest threat as over crowding gets worse and journey times get longer. This is precisely why cities across the world are putting tram routes in these corridors. What is being proposed in Edinburgh, that of putting a tram on a successful bus route, is exactly what has proven most successful (both in terms of attracting new passengers and raising revenue) elsewhere.”
