However, with the rapid concentration of the population, urban traffic problems, such as congestion, environmental pollution, and traffic accidents, have significantly affected traffic efficiency and urban development.

A novel method was discussed for the preparation of petroleum-based mesophase pitch with a large domain structure and an ordered microcrystal structure. A condensation pitch with a certain amount of anisotropic structures was generated from an aromatic-rich oil from FCC slurry oil by heat treatment. The aromatic-rich oil was used to prepare mesophase pitch by inductive thermal condensation with n-heptane insolubles of the above condensation pitch as seed.
