The newly opened Qingyang and Jinwu expressways have benefited citizens in Changzhou City to travel, but the high traffic and faster speed also add difficulties to maintenance.

Recently, the road administration of Wujin District in Changzhou has introduced the solar-powered devices to assist maintenance for the first time. These devices, with orange-red reflective overalls and safety helmets, wave small red flags in their hands to warn drivers at the maintenance areas. They not only help reduce the labor cost but also increase the safety of maintenance operations.
