Zebra crossing originated from jumping stones in ancient Rome. As early as ancient Rome, in some streets of Pompeii, chariots and horses crossed with pedestrians, which often caused traffic jams and accidents in the city. To this end, people separated the sidewalk from the carriage road, raised the sidewalk, and built protruding stones on the road near Ma Lukou as a sign to instruct pedestrians to cross the road. Pedestrians can walk slowly across the road on these jumping stones. When the carriage is running, the jumper is just between the two wheels of the carriage. Later, many cities used this method. /kloc-At the end of 0/9th century, with the invention of automobiles, the traffic in the city was rolling, and people crossed the road at will, which hindered the traffic. The previous kind of rock jumping can't avoid frequent traffic accidents. In the early 1950s, the British designed a crosswalk on the street, stipulating that pedestrians should only take crosswalks when crossing the street. So a series of eye-catching crosswalks appeared on the streets of London, which looked like white stripes on zebras, so people called them zebra crossings. When the driver sees this white line, he will automatically slow down or stop to let pedestrians pass safely.
