Automatic Vehicle Location and Control (AVLC) leads to more efficient services and helps you meet performance KPIs.
Michelangelo carved the statue of David out of a single piece of marble with a hammer, a couple of chisels and some sandstone. You can do the same with your transportation network.
Building and managing a transport network is not an easy task, but the right people with the right tools can create wonders.
The right people can be found in the modern, forward-looking public transport authority as well as in many bus, tram and light rail operators. They have been selected for their skills and belief in public transport.
Often with years of experience, they have a deep understanding of bus operations and network design. They push the boundaries of service delivery and help ensure the viability of the operating companies.
To make the most of this intellectual pot of gold, they need the right tools.
The right tools, of course, have changed over time.
It used to be that a large desk with rolls of transparent paper and a pencil was the right tool. Planners would work
At the depot, the right tools were a whiteboard, printed timetable lists and a dedicated private radio system to let operations management talk to drivers.
Locating the vehicle was a case of asking the driver where they were (not much help if they were lost) and then managing operations based on the control room’s mental picture of the services.
Passengers got a printed timetable at their stop (updated every 12 months) whether they needed it or not.
Historically, the government also had little in the way of tools and were reliant on the transport operators to report performance.
As responsibility for designing and operating routes has shifted away from operators, the transport authorities have taken up the mantle. They are now actively seeking to improve both service quality and frequency, putting services where people want to go and running services at the rate and times that they are needed.
To help with this, transport authorities have embraced new technologies and now use maps based on travel time (
The modern transport company also uses a specialist planning tool to
In all these cases, the right tool in the right
Savings made by operating companies in operations will result in lower costs, allowing authorities to buy more services for the same amount of funds.
In addition to planning and asset management tools, a key tool used around the world is Automatic Vehicle Location and Control (AVLC) systems.
These systems track buses and trams in real time and report the vehicle’s location, allowing operators to manage their fleet and deliver real-time information to passengers. The systems also provide other economic benefits by way of reduced travel time (
Passengers benefit too through having easy access to accurate real-time information and improved arrival time reliability.
Because they typically operate across a city serviced by multiple operators, AVLC systems are normally purchased and owned by the transport authority.
There are many good reasons for governments to buy a tracking and control system, keeping both their own needs and those of the various operators in mind. Governments get the operational performance monitoring they need, and at the same time operators get a tool to help them deliver the very contracts the authority wants
This is a classic case of buying the right tool rather than the cheapest tool.
The right tool becomes an essential part of the city’s
So, what does the right AVLC tool look like? This will vary based on your perspective. If you are a public transport authority, then the following things may be important to you:
If you are an operator, there is quite a different and longer list that is focussed on helping deliver services:
With hundreds of vehicles under your control, you need the system to tell you when things are not going to plan. Automatic alerts should identify:
When a vehicle goes off track,
Has exceeded operational tolerance (early/late schedules, headway variance), or
Is wanting to communicate.
Having identified an issue, you need to be able to determine options to resolve the issue and direct your fleet to enable the preferred option. Built-in workflows really help with this.
Communication between your drivers and your control room should be straightforward and ideally will make use of the AVLC data network, eliminating the need for a standalone communications network. This can deliver significant savings to an operating company.
Mobility is also important. Bus operators are often called on to provide supplemental services that may include rail replacement, event services for concerts and sporting fixtures and specialist charter services. Having the ability to fit out a vehicle quickly with a temporary, tablet-based track and control system that fits seamlessly into the primary AVLC system is invaluable.
Drivers are the primary contact point with passengers and they need to be empowered. Any AVLC system should help drivers keep to schedule by providing information on how they are running against the schedule, or the current performance against headway targets for each route. To help them help passengers, the system should list upcoming stops and provide map-based directions to newer drivers on the current route.
By using vehicle monitoring to identify and then train drivers who accelerate and brake hard, the right tool will help improve ride quality for passengers and save fuel and maintenance costs.
Emergency alerts will provide improved security for your drivers.
Seeing the tracking history of vehicles and service performance over time helps you understand how you are performing against your operating contract.
Having daily performance metrics across the network helps keep the focus on service standards and allows the development of solutions that maximise the delivery of services against the contract.
It also makes sense for any control system to open the door to other future uses, such as:
Headboard/destination sign management
Integrated support of autonomous vehicles within fleet operations
Finally, depending on who has responsibility for the public-facing help desk, operators or authorities will also want:
The ability to communicate with passengers in the event of service disruption, ideally through on-board displays and audio, at-stop displays with audio, the web and mobile apps.
To see the historic location of vehicles to answer customer issues such as: “I left my phone on the 435 near Smith St around 10:00am. Can you get the driver to check if it is still there?"
It has been said that “A wrench is a great tool, just don’t try to drive nails with it”. This analogy applies strongly to public transport operations.
The right tool is far more than just a specialist knife for the transport authority. The range of benefits that can be gained and number of use cases that can be identified require a multifaceted tool more akin to a Swiss army knife.
In Australia and New Zealand, the burden of picking the right tool falls largely on the public transport authorities. It is essential that they keep a high level view and never lose sight of the bigger picture, which is delivering a seamless passenger experience.
There is no doubt that we have some fantastically skilled people in both our transport authorities and in bus and tram operations. They are the Michelangelos of the public transport world.
Given the right tools, they can create and deliver transportation far beyond expectation. Transit leaders’ job is to think big, be the patron of public transport, commission their ‘David’ and then give both authorities and operators the tools they need to create a true masterpiece of public transport.
