Abstract:Sharing corridor designing for arterial roads is defined as integrating two or more arterial roads into a definite corridor in a limited section, which involves multi-systematic and multi-level problems connected with both junctions and corridor. In recent practices of planning and building, sharing corridor designing is shifting from a passive mode to a positive mode and becoming one of solutions for durable urban transportation developing mode. Delivering and analyzing projects involved sharing corridor layout of roads throughout the world, the writer gives definitions for different sharing corridor layout. Furthermore, a brief analysis of sharing corridor designing is focused on function definition, framework, cross section, lane calculation, junction planning and traffic management. Lastly a special architecture and characteristic sections for sharing corridor designing were developed.
