To get a better understanding of visitation in its parks, the Agriculture, Fisheries and Conservation Department (AFCD) of Hong Kong has worked with Eco-Counter since 2017, and recently improved its monitoring program in two major country parks.

Since 2017, Eco-Counter has been a supplier to AFCD for country parks and has worked with two crucial divisions of the Country Parks Branch.

• Country Parks Management Division: We provide automated pedestrian and bicycle counting systems to various country park management centers. The goal is to understand the usage of hiking and mountain bike trails over time (including the impact of events and seasons), make data-driven decisions about the construction and renovation of trails, and minimize conflicts between hikers and mountain bikers.
• Country Parks Ranger Services Division: In 2021, Eco-Counter supplied and installed 28 outdoor automatic people counters at the main entrances of Aberdeen and Tai Lam country parks. We also provided data analytics services with monthly reports. The aim of this project is to track daily visitor attendance and patterns continuously and automatically, helping in the planning of facility management, visitor service, public education, and nature conservation.

The local context

Out of the total 1,092 km2 of Hong Kong land’s, three-quarters is countryside, including various landscapes such as beaches, woodlands, and mountain ranges. Hong Kong’s natural areas are split into 24 different “country parks”, covering a total area of 440 km^2.

Country Parks were created for the purposes of nature conservation, countryside recreation, and outdoor education. These beautiful parks comprise scenic hills, woodlands, reservoirs, and coastlines in all parts of Hong Kong.

Park management in Hong Kong deals with fire risks (that are present for six months out of the year), litter management, and providing the best level of service to park visitors (i.e. access to facilities, and the four long distance trails).

Finally, country park managers are highly concerned with fauna and flora protection, so finding a balance between welcoming visitors and protecting nature is a key priority (more than 3,100 species and varieties of vascular plants have been recorded in Hong Kong, approximately 2,100 of which are native).

Visitation monitoring in Hong Kong country parks

A scattered view and manual counting (2017-2020)

Since 2017, Hong Kong park managers have been measuring visitation with 15 automated counters installed in 5 different country parks, with different offices acquiring monitoring systems separately. This helped local authorities gain insight on the busiest hours, days and months to improve visitor experience.

For example, on Pyramid Hill in Ma On Shan Country Park, automated counters have enabled AFCD to understand trail usage to the top of hill and make the right decisions about hiking trail renovations.

In addition to automatic counting, manual counting is done by park rangers at key locations to gain information on attendance, but on limited time periods and locations as this type of data collection requires heavy manpower.

The pilot project (2020 – 2022)

Starting in 2020, a large project was undertaken to gather and build a more comprehensive overview of two major Hong Kong country parks.

Permanent counters were installed at each main and secondary entrance of these two country parks, to precisely measure the number of visitors coming in and out. In total, 14 permanent counters were installed in each park.

Comparison of manual counts vs. automatic counts

Manual counts were being collected at the two parks, but only at certain hours and certain sites. This means that the data lacked representativeness, which is essential for decision-making. One of the goals of this project was to progressively roll out automatic counting to allow for better, more accurate, and more representative data. 

With help from Eco-Counter’s Data Services team, AFCD compared manual counts with automatic counts. Results showed great correlation between the two data sets (a 72% correlation rate overall), but very high differences in volume, with automatic counts being over 4 times as high during some periods, such as Chinese New Year festivities.

Correction factors calculation

AFCD & Eco-Counter also did some manual count validations to achieve the best possible level of accuracy. 

As can happen with PYRO counter algorithms, group masking can sometimes lead to an underestimation of counts. By doing count validation on the field, it is possible to determine a correction factor that can then be used to improve the data’s accuracy. In those two country parks, count validation was done on all 28 sites, which enabled Eco-Counter to statistically adjust automated counts and provide more accurate visitation numbers for each entrance.

Total visitor numbers report

All this work allowed Eco-Counter to give AFCD a comprehensive report on their park visitation that used reliable, accurate, and verified field data derived with fully transparent methodology. 

These data are updated each day and are visible on our Eco-Visio analysis software. The report is updated every quarter by the Eco-Counter Data Services team, providing park managers with global attendance figures, as well as detailed visitation by entrance (total and % split). 

These visitation reports will help park rangers optimize visitor services, improve information share to visitors, and improve maintenance works on the trails. 

Future studies & analyses

In March 2024, Eco-Counter won a new contract to provide services for people counters’ upgrade work and data analytics in Robin’s Nest Country Park, the newest 25th country park in Hong Kong.

In April, Eco-Counter won the tender contract AFCD/SQ/334/23 “Provision of Services for Supply, Installation and Maintenance of Outdoor People Counters and Data Analytics in Country Parks of Central New Territories and Hong Kong Island”.

About Eco-Counter in Hong Kong

In response to the increased number of counters in operation (over 40 counting sites) and the high demand for after-sales/maintenance services from Hong Kong customers, Eco-Counter opened a wholly owned subsidiary in Hong Kong, ECO COUNTER LIMITED, in September 2023. Mr. LI Jun, the former Managing Director of Eco-Counter in Shanghai, has been transferred to Hong Kong to serve as the Executive Managing Director of ECO COUNTER LIMITED since January 1, 2024.

Since the establishment of ECO COUNTER LIMITED, all Eco-Counter activities in Hong Kong and Macao are conducted through this new subsidiary.
