The consolidated data of a spot speed study for a certain stretch of a highway is given in the table.Speed Range
(kmph) Number of observations 0-10 7 10-20 31 20-30 76 30-40 129 40-50 104 50-60 78 60-70 29 70-80 24 80-90 13 90-100 9
The "upper speed limit" (in kmph) for the traffic sign is
| Speed Range (kmph) | Number of observations |
| 0-10 | 7 |
| 10-20 | 31 |
| 20-30 | 76 |
| 30-40 | 129 |
| 40-50 | 104 |
| 50-60 | 78 |
| 60-70 | 29 |
| 70-80 | 24 |
| 80-90 | 13 |
| 90-100 | 9 |

Top Questions on Geometric design of highways
- A car is travelling at a speed of 60 km/hr on a section of a National Highway having a downward gradient of 2%. The driver of the car suddenly observes a stopped vehicle on the car path at a distance 130 m ahead, and applies brake. If the brake efficiency is 60%, coefficient of friction is 0.7, driver's reaction time is 2.5 s, and acceleration due to gravity is 9.81 m/s2, the distance (in meters) required by the driver to bring the car to a safe stop lies in the range
