An estimated 62 million vehicles are expected to hit the highways nationwide in China during the upcoming five-day May Day holiday starting May 1. Traffic peaks are likely to come on the first and the last two days of the five-day break. New energy vehicles are expected to account for nearly 20 percent of the total daily highway traffic volume during the holiday. To avoid charging delays for electric vehicles during the holiday, transportation authorities in some areas have worked with other departments to implement related measures.
