Maintenance Work Reporting on Linear Asset
This about description explains how you can register maintenance work on a linear asset using reference to elements, distance and offset to indicate where on the linear asset the works should be performed. A road is used as an example in the following three scenarios. The maintenance work can be both a length and a position. If entering element IDs for the start and end reference information the length will be filled automatically with the difference between these elements.
Pre-Postings are fetched from the start point of the maintenance work. Offsets are not used to control pre-postings.
Functional description on fault reporting
Example 1 - The maintenance work is 100 m from the side of the bridge (E2) facing the exit road (E3)
Since the fault is located between E2 and E3, you enter the position as following:
- Start Reference Information: E2 - Start Reference is position 30 (end point of E2), since the chosen direction is towards E3
- End Reference Information: E3 - The chosen direction of the position of the maintenance work
- Distance: 100m (100m from the start reference, that is the end point of E2)
Example 2 - The maintenance work is 100 m from the side of the bridge (E2) facing the rest area (E3)
Since the fault is located between E1 and E2, you enter the position as following:
- Start Reference Information: E2 - Start Reference is position 20 (start point of E2), since the chosen direction is towards E1
- End Reference Information: E1 - The chosen direction of the position of the maintenance work
- Distance: 100 m (100m from the start reference, that is the start point of E2)
Example 3 - The maintenance work is on the bridge (E2) 4 km before the end facing the exit road (E3) (or 6 km after the start facing the exit road)
Since the fault is located on E2, you enter the position as following:
- Start Reference Information: E2 - Start Reference is position 30 (end point of E2), since the chosen direction is towards E3
- Offset Y: 6 km
- End Reference Information: E3 - The chosen direction of the position of the maintenance work
- Distance: 0 m (since the maintenance work is on the bridge)
Or as following:
- Start Reference Information: E2 - Start Reference is position 20 (start point of E2), since the chosen direction is towards E1
- Offset Y: 4 km
- End Reference Information: E1 - The chosen direction of the position of the maintenance work
- Distance: 0 m (since the maintenance work is on the bridge)
Technical description on fault reporting
Example 1 - The maintenance work is 100 m from the side of the bridge (E2) facing the exit road (E3)
Alternative 1
- Start Reference Information: E2 (Bridge)
- End Reference Information: E3 (Exit Road)
- Distance: 100 m
The value E3 Start Point (40) is greater than the value of E2 Start Point (20). This leads to:
- A positive parameter A
- Distance is a positive number --> Positive parameter B
- A*B is positive --> Distance calculation should be done from the End Point of E2 (30)
The distance to the maintenance work from start will then be: 30 + A * (100 m * 1/1000 km/m) = 30 + 1 * 0,1 = 30,1 km
Alternative 2
- Start Reference Information: E2 (Bridge)
- End Reference Information: E1 (Rest Area)
- Distance: -100 m
The value of E1 Start Point (9,8) is less than the value of E2 Start Point (20). This leads to:
- A negative parameter A
- Distance is a negative number --> Negative parameter B
- A*B is positive --> Distance calculation should be done from the End Point of E2 (30)
The distance to the maintenance work from start will then be: 30 + A * (-100 m * 1/1000 km/m) = 30 + (-1) * (0,1) = 30,1 km
Example 2 - The maintenance work is 100 m from the side of the bridge (E2)
facing the rest area (E1)
Alternative 1
- Start Reference Information: E2 (Bridge)
- End Reference Information: E1 (Rest Area)
- Distance: 100 m
The value of E1 Start Point (9,8) is less than the value of E2 Start Point (20). This leads to:
- A negative parameter A
- Distance is a positive number --> positive parameter B
- A*B is negative --> Distance calculation should be done from the Start Point of E2 (20)
The distance to the maintenance work from start will then be: 20 + A * (100 m * 1/1000 km/m) = 20 + (-1) * 0,1 = 19,9 km
Alternative 2
- Start Reference Information: E2 (Bridge)
- End Reference Information: E3 (Exit Road)
- Distance: -100 m
The value of E3 Start Point (40) is greater than the value of E2 Start Point (20). This leads to:
- A positive parameter A
- Distance is a negative number --> negative parameter B
- A*B is negative --> Distance calculation should be done from the Start Point of E2 (20)
The distance to the maintenance work from start will then be: 20 + A * (-100 m * 1/1000 km/m) = 30 + 1 * (-0,1) = 19,9 km
Example 3 - The maintenance work is on the bridge (E2) 4 km before the end facing the exit road (E3) (or 6 km after the start facing the exit road)
Alternative 1
- Start Reference Information: E2 (Bridge)
- Offset Y: 6 km
- End Reference Information: E3 (Exit Road)
- Distance: 0 m
The value of E3 Start Point (40) is greater than the value of E2 Start Point (20). This leads to:
- A positive parameter A
- Distance is 0 and Offset Y is positive --> negative parameter B
- A*B is negative --> Distance calculation should be done from the Start Point of E2 (20)
The distance to the maintenance work from start will then be: 20 + A * (0 m * 1/1000 km/m + 6) = 20 + 1 * 6 = 26 km
Alternative 2
- Start Reference Information: E2 (Bridge)
- Offset Y: -6 km
- End Reference Information: E1 (Rest Area)
- Distance: 0 m
The value of E1 Start Point (9,8) is less than the value of E2 Start Point (20). This leads to:
- A negative parameter A
- Distance is 0 and Offset Y is negative --> positive parameter B
- A*B is negative --> Distance calculation should be done from the Start Point of E2 (20)
The distance to the maintenance work from start will then be: 20 + A * (0 m * 1/1000 km/m + (-6)) = 20 + (-1) * (-6) = 26 km
Alternative 3
- Start Reference Information: E2 (Bridge)
- Offset Y: 4 km
- End Reference Information: E1 (Rest Area)
- Distance: 0 m
The value of E1 Start Point (9,8) is less than the value of E2 Start Point (20). This leads to:
- A negative parameter A
- Distance is 0 and Offset Y is positive --> negative parameter B
- A*B is positive --> Distance calculation should be done from the End Point of E2 (30)
The distance to the maintenance work from start will then be: 30 + A * (0 m * 1/1000 km/m + 4) = 30 + (-1) * 4 = 26 km
Alternative 4
- Start Reference Information: E2 (Bridge)
- Offset Y: -4 km
- End Reference Information: E3 (Exit Road)
- Distance: 0 m
The value of E3 Start Point (40) is greater than the value of E2 Start Point (20). This leads to:
- A positive parameter A
- Distance is 0 and Offset Y is negative --> positive parameter B
- A*B is positive --> Distance calculation should be done from the End Point of E2 (30)
The distance to the maintenance work from start will then be: 30 + A * (0 m * 1/1000 km/m + (-4)) = 30 + 1 * (-4) = 26 km
