The cross-border passenger trips at all Macao border checkpoints are expected to hit 5.2 to 5.4 million during the Chinese mainland's seven-day National Day holiday from Oct 1 to 7, with a daily average of 740,000 to 770,000, according to the Public Security Police Force (CPSP).

Peak passenger flows are expected on Oct 3 and 4, when the daily throughput could exceed 800,000.

The CPSP said it will implement crowd control measures at scenic spots and share real-time passenger and vehicle data with Zhuhai and Hong Kong to support pre-emptive passenger flow forecasting and contingency planning.
