Minimum Inside Shoulder Width of Multi-Lane Freeway Considering the Need for Vehicle Parking
The Technical Standard of Highway Engineering of China regulates that 8-lane freeways should provide a 2.5-meter-width inside shoulder. While several freeways in China (such as Shanghai-Nanjing Freeway, Shenyang-Dalian Freeway, and Guangzhou-Foshan Freeway) just completed widening to eight lanes, there were no inside hard shoulders set and none are wider than a 0.75-meter marginal strip. In this study, the relationship between vehicle speed and inner lateral clearance was analyzed. Through field investigation, vehicle speed and inner lateral clearance of the innermost lanes were collected. Statistical analysis was carried out and regression analysis was adopted to develop the relational model between the two parameters. Then, a linear model was proposed. After conducting revision of the model by considering the practical factors, the model can be applied to calculate the inside shoulder width. Finally, the recommended values of inside shoulder width were given. This study is aimed at providing a theoretical basis for setting the width of inside shoulders of multi-lane freeways.
