The world’s largest human migration is currently underway as some 2.99 billion trips are expected to be made across China during the Spring Festival holiday season from Jan. 21 to Mar. 1. To guarantee road safety and smooth trips, Chinese police have also strengthened their efforts together with advanced technology.

Of those heading home for the holiday, some 380 million are expected to hit the road on motorcycles and cars. In response, Chinese map app Amap is providing recommended smart maps for group travelers with data input from hundreds of highway service centers and information from local traffic police. It also includes 75 free maintenance stations for motorcyclists.

Many migrant workers in China choose to head home for the Spring Festival via motorcycle, as it is cheaper than train or plane trips.

The new smart map service will be even better this year thanks to upgrades, such as road conditions given by police in advance, messages that provide info on available roads to circumvent closed roads, and accurate weather and other service information, said Liu Zhenfei, president of Amap.

As roads are inevitably subject to construction, accidents, or closures, the traditional practice of traffic control, that is, placing ordinary reflective cones as reminders to drivers, is sometimes insufficient to avoid accidents. The smart map, on the other hand, can inform people in advance to avoid certain sections and help prevent accidents or congestion.
