Hold bus services to higher standards
Let's also employ more technology, set up high-level task force to effect real improvement
Everything seems fine with the buses here, according to the Public Transport Council (PTC). SBS Transit "complied with all the standards," the PTC said in October, while SMRT has only "been fined for three failures" for late departures in the six months until May.
Tell that to commuters, though, and you may hear far different accounts as their stories come gushing out.
One commuter I know taking Service 75 during peak hours in mid-October, for example, waited for 20 minutes one day and then had two buses arrive together as soon as he reached the bus stop the next morning. It is an experience commonly echoed by many.
Another commuter I spoke to compares bus drivers' stop-and-go driving techniques to the rides hurtling people around at Universal Studios. More stories like these abound.
With over three million passenger-trips on buses every day, the impact of small delays or other problems is huge. Not unexpectedly, the Singapore Management University's 2010 Q2 Customer Satisfaction Index found that "customer satisfaction scores for both the Mass Rapid Transit Systems and the public buses sub-sectors have been declining since 2007".
So what can be done? Several steps could make commuting by bus better.
For one, Singapore could start using best practices. Research last year by Imperial College's Mark Trompet, for example, showed that New York set a standard where buses must arrive within three minutes after their scheduled arrival time and buses in Paris must arrive within two minutes. Where schedules in Singapore do exist, he said, buses are supposed to arrive within five minutes before or after their scheduled time.
That 10-minute window can cause dissatisfaction, or worse. As research by University of Arizona Professor Ryan Johnson mentions, a "bus-bunching phenomenon has frustrated passengers in cities around the world". Other research cited by Mr Trompet showed that bus arrival irregularity "discourages commuters' use of public transit".
If we're going to get people to ride the bus and like it, moving to the levels of New York or Paris could help. While the PTC does measure 11 standards, tracking others like "regularity" or "customer satisfaction" as is done in Sydney and setting higher targets such as arriving within three minutes of the scheduled time - rather than "at least 80 per cent of bus services to operate at headway (frequencies) of not more than 10 minutes during weekday (excluding public holidays) peak periods" - could lead to higher service levels.
THE TECH IS OUT THERE
Another step would be to leverage leading-edge technology fully. In the United States, University of California Professor Alex Bayen's research group is merging radar, lidar, detectors embedded in roads and video with input from GPS devices to "detect patterns and build a prediction engine".
One initiative in Sydney, according to the New South Wales Auditor-General, is a real time bus monitoring system that "can also provide traffic light priority for late running buses". While technology is used here, too, bus companies still have staff standing at bus stops monitoring bus arrivals with a watch and paper!
Steps like changing bus priority real-time, using better prediction models for scheduling and using technology to help enforce bus priority in bus lanes could result in higher service levels. While usage of some of this technology may already be in the pipeline here, employing more of it and communicating the results could also be beneficial.
Improving bus transport is important for reducing commute times, raising productivity and increasing usage of public transportation, among other reasons. Despite efforts to do better, Land Transport Authority data until 2008 showed that bus commuting times had remained static at about 42 minutes for a decade. Even though it turns out that SMRT is a member of the International Bus Benchmarking Group that shares global best bus practices, data still indicates that arrival times and other results lag best-in-class standards.
Actually solving the problems may take more focus than what has been the case so far. For example, the situation in Singapore may be serious enough to warrant an independent and high-level task force to develop and implement strategies that lead to real improvement. Setting and achieving higher standards as well as taking steps to leverage technology even better could also make a big difference. There are a multitude of other opportunities.
Public transport here has the potential to be world-class and improvements will benefit productivity as well as commuter satisfaction levels. The critical next step is to make the change happen.
