Hong Kong's Immigration Department estimated on Thursday that 7.78 million passengers will pass through land, sea and air control points during the Christmas- New Year period, 11 percent more than last year.

About 2.74 million passengers, 305,000 daily, will pass through Lo Wu, the busiest control point, said the report.

For outbound traffic, the busiest day at Lo Wu is expected to fall on December 25, with 185,000 passengers leaving Hong Kong. Inbound traffic will be heavy on January 1, with 172,000 people arriving.

Passenger traffic at Lok Ma Chau, Lok Ma Chau Spur Line and Shenzhen Bay control points will also be heavy, with forecast daily averages of 105,000, 118,000 and 95,000 passengers, respectively.

The department will man a joint command center at Lo Wu with Police, Customs and the MTR Corporation to monitor traffic conditions.

It advises cross-boundary passengers to plan their trips in advance and travel during less-busy periods in the late morning and early afternoon, and monitor radio and television broadcasts on traffic conditions.
