Stationing is the fundamental system of measurement used for road layout and construction. Stations are reference points that are placed along the horizontal measurement of a route
centerline or a baseline at some regular interval. Generally, the distance between two adjoining stations along a route is 100 feet. The first station located at the beginning of the baseline is 0+00, and the next station located 100 feet from it is 1+00. Therefore, a station number of 10+34.05 denotes 1,034.05 feet (10*100 + 34.05) from the starting station.
The station numbers increase from west to east or south to north based on the cardinal direction of the overall highway. For highway projects, a starting reference station is first established, and then all distances along the route centerline are measured from that point location. You can add event data to routes by entering station numbers in the Line Events widget. The station data is translated to routes and measures for storage.
You can use the stationing data as an input for adding linear events by using these three scenarios:
- Create a starting or base station on the route and enter the station values as an offset from that station.
- Identify a starting or base station on the route and enter the station values as an offset from that location.
- Use the preexisting stations on the route to calculate or enter the measures in the form of station values.
Entering the station values by creating a starting or base station on the route
You can use this method when no stations are present on the route. You'll create a starting or base station on the route, and enter the stationing values for measures. The measures will be located at an offset from the starting station.

Using the preexisting stations on the route to calculate or enter the measures
You can use this method when stations exist on the route. The measures will be calculated using the location and values of the preexisting stations.
In the following example, there are two stations on the route. Station A is an equation point with 139+55 Ahd and 140+55 Bck values. Station B has the station value of 141+60.96. The stations increase in value following the direction of calibration of the route, which is from left to right on the map. The measures on the route will be located by taking these two stations into consideration.

- Type the station value.
The from measure location is placed at an offset from the nearest station. Since the station value entered was 139+86.62, the nearest station was station A. Hence, the from measure location is positioned at an offset from station A, which has a value of 139+55 Ahd.

The to measure location is placed at an offset from the nearest station. Since the station value entered was 141+89.07, the nearest station was station B. Hence, the to measure location is positioned at an offset from station B, which has a value of 141+60.96.

注：
Notice that at the equation point, that is, station A, there exists a difference in values between the Ahead (139+55 Ahd) and Back (140+55 Bck) stations. Assume that you have to enter a From measure value of 139+60. Using the logic provided above, when you enter the value in the text box, a pop-up appears so you can select the exact location of the measure from two available options. The reason is that the From measure value of 139+60 can be located from both 139+55 Ahd and 140+55 Bck.
When you select the first option from the pop-up, the From measure is located to the right of station A (nearest station), as the location is determined referencing the 139+55 Ahd value.
When you select the second option from the pop-up, the from measure is located to the left of station A (nearest station), as the location is determined referencing the 140+55 Bck value.
Selecting one of the options will populate the Station text box.
