JIADING District is using new materials and technologies to expand lanes for bicycles and small motorbikes.
A new system integrates sidewalks with non-auto areas and has been used on Huancheng, Yongsheng and Yecheng roads. The system increases road capacity in areas where roads themselves cannot be widened.
To prevent vehicles from driving on these areas, signposts have been erected along the way.
New materials such as SBS modified pitch have been applied on roadways to reduce noise by three decibels and improve the environment for residents. The pitch can also be used to reduce water, fog and glare from road surfaces at night.
Lower carbon levels are induced by applying water-permeable concrete and pitch. That helps water seep underground and lessens storm-drain runoff during heavy rain.
The new material also reduces the phenomena known as "urban heat islands."
