Adding linear events by station measures

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.

    • 停用重叠 - 系统调整现有事件的测量值以及开始和结束日期，以使新事件不会出现时间和度量值重叠。

      

    • 合并重合事件 - 当新事件的所有属性值与现有事件完全相同时，如果新事件在测量值方面与现有事件相邻或重叠，则将新事件合并到现有事件中，而且测量范围将相应扩大。

      

    • 防止测量不在路径上 - 开始和结束测量的输入测量值落在所选路径上测量值的最小和最大范围内。
    • 将事件保存到主要路径 - 将事件添加到具有并发路段的主要路线。 如果启用，对于所选路线上的任何并发路段，都可以选择将事件添加到每个并发部分的哪条路径。 当所选网络配置了优先级规则时，此选项可用。
17. 单击下一步。

    • Checking the Go to the next measure upon save check box results in prepopulating the From measure value using the To measure value of the present section to continue the event creation process. For example, this will occur if events are created on the route using a From measure value of 0 miles and a to measure value of 0.289 miles. If you click Save, using this option checked on the Attribute Set tab, the Add Linear Events widget is prepopulated with the value of 0.289 miles as the From measure value for the new events.

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.

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.
