摘要：	A highway alinement design process called "curvilinear alinement" is described. It is based on a process called "relation design", which means that no more single design elements with minimum or maximum limiting values are put together more or less arbitrarily; rather, design element sequences are formed in which the design elements following one another are subject to specific relations or relation ranges. Quantitative criteria are given for evaluating the driving behaviors of motorists in the transitions between successive design elements as well as tuning the operating speed to the design speed for single design elements on two-lane rural roads. The curvilinear alinement can provide sounder, more consistent road alinements. The suggested procedure for modern highway design provides better quantifiable and more sophisticated criteria than those that already exist in western European design guidelines. It is recommended that curvilinear alinement design be evaluated for inclusion as a recommended design process in the AASHTO Green Book for two-lane rural roads.
