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
