 Much has been written with regards to ABOUTAsia's 'crowd avoidance' research around the Angkor temples.The company routes its tours of Angkor Wat and the surrounding temples with proprietary research garnered with surveillance walks, footfall counts, and "surveys of pedestrian traffic patterns" to graph the number of visitors and keep travelers away from bus tours.According to Merope Mills of The Guardian, with over 2.5 million visitors to Cambodia every year ABOUTAsia's research is increasingly important for both conservation and visitor experience.
