| 11. | Warning signs are often used where sight distance is insufficient.
|
| 12. | It is also important on minor roadways for safety considerations such as driver sight distance.
|
| 13. | The line of sight distance " d " of this station is given by the Pythagorean theorem;
|
| 14. | Thus, the maximum service range of the station, is not equal to the line of sight distance.
|
| 15. | Minimum sight distances were kept at.
|
| 16. | Lower speed roads can have sharper curves, less banking, less sight distance, and sharper hill crests and valleys.
|
| 17. | It is characterized by sharp curves, limited sight distance, narrow shoulders, and lack of merge lanes at interchanges.
|
| 18. | The desired stopping sight distance ( S ) is determined by the speed of traffic on a road.
|
| 19. | The proper equation depends on whether the vertical curve is shorter or longer than the available sight distance.
|
| 20. | Before releasing the accident scene and allowing restoration of service, the NTSB also conducted a final sight distance test.
