Bristol Airport’s new flow management solution provides a seamless and detailed picture of how their passengers move through and use the airport. The information gives the airport added value, unlocks new business opportunities and improves services.

In 2016, passenger numbers exceeded seven million for the first time in Bristol Airport's history. To help obtain an in-depth cohesive view of passengers’ movement patterns, guide daily and long-term operational and business decisions, and drive higher profitability and passenger satisfaction as this number continues to rise, the airport last year implemented an all-encompassing passenger flow measurement and analysis platform named BlipTrack. 
The high-tech solution provides Bristol, which is one of the UK´s fastest growing airports, with a cohesive, wide-ranging view of passenger movements from carpark entrance to gate – and gate to carpark exit. 
It presents the airport with a unique opportunity to get ahead of traffic and passenger flow issues before they happen and to more efficiently plan resources in and around the airport, as well as provide retailers in the concession areas with better information to help increase their revenue.
Paul Davies, Operations Director at Bristol Airport, says, “We wanted to introduce a state-of-the-art technical solution to the challenges airports face in improving customer flow management in the terminal.  We had very high expectations prior to the introduction of the system, and I am very happy to say that the outcome has proved very successful. The system has capabilities of further enhancements, which will provide other long-term solutions in the future.”
Numerous other international hubs, including Amsterdam Schiphol, Auckland and Billund airports, are following suit. The operators understand that to improve individual areas of operations; it is essential that passengers´ journeys are seen as one process, rather than as a string of isolated events. Understanding that all individual events influence each other is key to unlocking potential gains. These airports have recognised that comprehensive passenger flow data is indispensable for guiding physical expansion plans, and for streamlining operations to accommodate rapid passenger volume growth.
As the solution enables the airport to measure and identify flow patterns throughout the entire airport, it allows them to see the impact of the various actions they implement.  With improved operational efficiency and more streamlined check-in and security processes, passengers at Bristol Airport will not only enjoy a faster and more pleasant transit experience but inevitably also spend more time in the concession areas, giving the airport’s retailers the opportunity to maximise non-aviation revenue.
Phil Holder, Head of Operations Support at Bristol Airport, explains, “Before we installed the BlipTrack solution, we were reliant on our control centre staff to detect queues, using CCTV cameras. This approach was very time-consuming and was only carried out at certain times of the day. Now we have coverage at our fingertips 24 hours a day, 7 days a week. We can now record information more consistently, enabling us to use service level agreements more fairly—not just over selected periods. In addition, as the solution collects data in real-time, it provides early warning if congestion occurs. This rapid information allows us to take fast, proactive measures before the situation escalates, such as opening up additional lines, reducing the risk of bottlenecks and frustrated passengers.”
Live Wait Time Information to Ease Passengers´ Minds
Holder also mentions the benefits of displaying wait-time information, saying that by presenting the length of time passengers could expect to be in the queue, their minds are set at ease, reducing their stress, as they are automatically reassured that there is no issue with this part of their ongoing journey. 
Using Flow Data to Boost Non-aviation Revenue  
“We will have a view of stacked passenger dwell times for each of the airport areas, from all carpark entries right through to the boarding gates and immigration. The data will help indicate which processes we need to improve, for instance the number and frequency of car park buses. We can measure when passengers arrive and how long it takes them to get to the terminal, which will help us plan bus timetables. By linking it to the boarding gates, we will have a good idea of what time passengers travelling to different destinations choose to turn up at the airport. It will also enable us to evaluate whether there is a need to increase the throughput in security, if airside concession dwell time is low,” ends Phil Holder. 
Bristol Airport can retrieve both live and empirical metrics about queue wait times in its processes, and specific flow patterns, such as walking routes, entrance and exit usage, and time spent in particular areas, such as carpark, check-in, security, lounges, gates, immigration and more. Patterns can be averaged over a day, week, month, a specific time of day, holidays, or a range of other metrics. Ultimately, this enhances the understanding of how disruptions or changes affect standard behaviour and helps the airport to optimise their operations in areas of interest. 
Besides Bristol Airport, the solution has also been adopted by other UK airports: Birmingham, Manchester and Edinburgh. And internationally, more than 25 international airports are reaping the benefits of this Danish-developed technology, including JFK Airport in New York, Dublin, Copenhagen, Milano, Oslo, Geneva, Brussels, Cincinnati and Keflavik
The solution is not only confined to airports, but it is also employed in road traffic optimisation efforts in Portsmouth, Port of Dover, Bangkok, Zürich, Aarhus, Stockholm and Auckland. In recent years, it has even been rolled out in train stations, ski resorts, amusement parks and at events all over the world.

Ever-increasing global travel volume is having a severe impact on airports like New Zealand’s Auckland International, which saw over 19 million passengers last year. The airport is taking the increased passenger flow and logistics issues seriously, using a unique combination of traffic and passenger flow measurement technology. The result? Faster travel times, acceptable wait times, less passenger stress and a wealth of information that helps the airports and the city to plan resources more efficiently.

Auckland - a growing hub for travel

Auckland Airport expects to host over 40 million passengers annually by the year 2044. To cope with the increase in passenger load, the airport embarked on a wide-ranging and world first combined passenger-flow and road-traffic measurement project, with the goal of obtaining a cohesive real-time view of people movement patterns, to guide daily and long-term operational decisions, maximise capacity and improve flow.

In its build, the airport has opted to aim for sustainability, while ensuring that they will not only have the capacity to handle the extra people, but also the capability to make the passenger journey as smooth and stress-free as possible.

Keeping things flowing

Smooth passenger flow, both in the arrival and departure terminals, and the concession and transit waiting areas, as well as on the roads surrounding the airport, is critical to the successful operation of an airport.

Issues with traffic flows can result in delays for passengers, airport staff and airline crew, resulting in disruptions to airport and airline operations.

To manage both passenger and traffic flow, Auckland Airport realised they needed to have a bird’s-eye view of the entire system, as well as detailed, up-close analysis of ongoing issues. They also needed a way to act when things start to bottleneck.

With several traffic monitoring projects in New Zealand, using the same technology, infrastructure consultants Beca was commissioned to extend the solution across the airport’s roading infrastructure. It now provides the airport with a seamless picture of traffic flow information between the airport and Auckland CBD (Central Business District, also called the city centre).

How it works

On the Road

Outside the airport, the solution measures traffic flow between the CBD and the airport, providing real-time data on reliability, vehicle counts and travel time.

It provides data about the mix of staff and passengers using the Park and Ride facility, enabling the airport to understand the performance better and regularly review how they can improve their facilities. This information is also analysed to help planning decisions for road network maintenance and infrastructure projects.

The insights, collected using a range of technologies, including radar and WiFi sensors, also help the New Zealand Traffic Agency (NZTA) to make informed traffic management decisions and has allowed for the implementation of a number of initiatives to improve the traffic flow to the airport. It includes optimising traffic signal timings, and combined with the recent opening of the newly constructed Waterview connection, has resulted in significant travel time cuts to and from the airport from the CBD and West Auckland.

Also, the real-time and historical BlipTrack data enables NZTA, via their new app RideMate and online, to display live travel times between the CBD and airport, as well as informing about days with a high risk of congestion. It enables road users to plan ahead, reducing both the risk of travellers missing their flight and airport employees coming in late for work.

Besides the benefits of real-time reporting, the historical data is used to detect driving time anomalies. Effectively, this means that the solution can pinpoint road sections and intersections where driving times deviate from the norm as a result of construction projects, incidents, roadwork, faulty traffic lights and other factors. With this information at hand, real-time traffic management can take place.

Richard Young, Senior Associate at Beca, says: “The intelligence that BlipTrack is delivering has already proved its value, by providing automated alerts on delays on vulnerable corridors, real-time counts on traffic flows and delays, and intelligence on the origin and destination of vehicle movements into the airport and to terminals and car parks.”

In the airport

Inside the airport, the solution provides metrics on passenger queue times and volume, as well as insight into passenger movement patterns throughout the international and domestic terminals´ departure and arrival processes.

It helps the airport better manage and support resources by focusing on high-demand locations and periods. Likewise, the data directly benefits passengers by displaying wait times at security checkpoints, managing passenger expectations and reducing queue-related stress.

Mark Croudace, Manager – Operations at Auckland International Airport, says: “BlipTrack was a critical investment. The data has provided valuable insight into our operational performance across both our assets and processes. Most importantly, it has enabled us to have meaningful conversations with our key operational stakeholders and vendors, as we collectively seek to improve the passenger experience.”

Changing the face of travel

Numerous other international airports, including Amsterdam Schiphol, Copenhagen, Dublin, Brussels, Bristol and Billund, are following suit. These airports have recognised that comprehensive, seamless passenger flow data is indispensable in guiding physical expansion plans, and for streamlining operations to accommodate rapid passenger volume growth, without compromising the passenger experience.

“By having Auckland Airport and Beca working together, and by sharing data between multiple solutions, BlipTrack provides a solution that no other product in the industry can currently reproduce – large-scale, seamless, door-to-door movement management between different modes of transport. And because it´s not only limited to certain areas, it can be considered as one of the first real, tangible steps to true multimodal traffic management,” ends Peter Knudsen, CEO of BLIP Systems.

Besides providing airports around the world with seamless passenger flow data, the solution is employed in optimisation efforts in road traffic applications in Switzerland, Thailand, Canada, the UK, Denmark and Sweden. In recent years, it has been rolled out in ports, train stations, ski resorts, amusement parks, and at events around the world.
