The Road Alignment is highway skeleton , direct carrier vehicle running , it controls the entire highway roadbed , bridges and culverts , cross along the facilities and structures such as the size and investment . The same time , driving safety , comfort , economy and the capacity of the vehicle plays a decisive role , once determined, will be linear existed for a long time , regardless of the pros and cons , and are difficult to change . Route alignment design merits of the decision can be played after the completion of the road safety , comfort , economy and the extent of its economic construction along , but also affect the development and utilization , the main factors of the living standards of the people , so the designer should special attention to the quality of alignment design . Primarily for the development of the road to our current standards based on the comparison of the old and the new specification , mainly to study the advantages and disadvantages of the main technical indicators of our linear specification highway . Compare our highways and urban roads route design specification . Analysis of the Sino-French linear geometry selected technical indicators and comparative study , mainly from law concept of highway design , graphic design and technology indicators , the longitudinal design technical indicators , and cross-sectional design technology indicators compare highway design , flexibility indicators and scope and so on. Finally, Japan 's main line of road geometric design specification analysis study , discussed from Japan Road mainline structural design , road classification and design level of the main line , and Japan road cross-sectional design specification indicators , Horizontal Alignment of indicators and profile design specifications detailed analysis and research . Rational design route indicator parameters and design methods of traffic road in China 's economic construction and security is of great significance . We must fully consider the many gaps due to different national conditions , philosophy , technology , practice should actively transform design concepts , fully absorb new ideas and new design concept . At the same time design ideas to be flexible , to avoid blindly apply the norms , in order to achieve suitable for China's national conditions \the overall design concept of the relationship , to ensure the sustainable development of highway construction \
