SPEEDS ON BENDS OF MAIN ROADS
| 项目名称： | SPEEDS ON BENDS OF MAIN ROADS |
| 摘要： | THE AIM OF THE STUDIES IS TO CLARIFY THE FOLLOWING RELATIONS: (1) ACTUAL SPEEDS OF VEHICLES ON THE BENDS OF MAIN ROADS IN RELATION TO THE RADIUS OF CURVATURE, TAKING ACCOUNT OF VARIOUS INFLUENCING FACTORS (FOR EXAMPLE WEATHER CONDITIONS); (2) RELATION BETWEEN THEORETICALLY DETERMINED DESIGN SPEED AND ACTUAL SPEEDS; (3) INFLUENCE OF THE GEOMETRY AT THE START OF THE BEND AND THE LENGTH OF THE BEND ON CHOICE OF SPEED; (4) DETERMINATION OF THE DIFFERENT SPEEDS ON RIGHT-HAND AND LEFT-HAND BENDS (BOTH ENTERING AND LEAVING THE BEND). THE INTENTION IS TO CARRY OUT RADAR SPEED MEASUREMENTS NEAR BENDS AND ON THE BENDS THEMSELVES IN BOTH DIRECTIONS OF TRAVEL, ON SELECTED AREAS OF MAIN ROADS, PARTICULARLY THOSE OUTSIDE BUILT-UP AREAS. |
