Switch route selection

There can only be one route from a specific entrance to a specific exit in a junction box. In cases where there is more than one routing option available, then the SWITCH ROUTE option will appear. This switch route option will allow you to select the appropriate route through the junction box and the appropriate turn restriction and other settings for this desired route.

• Select the entry segment of the junction box that you want to compare routes on.
• Hover over the appropriate exit turn arrow that you want to select the desired route.
• The switch route selection will appear between the restrictions and difficult turn options in the gray turn information box.
• Click the forward or back arrow to cycle thru the allowable routes.
• For a route that you wish to allow always select the green route from the entry segment to the exit turn arrow. In other words do not select a route that should not be disabled, select the route that should be allowed.
• A red arrow on the exit turn arrow means that any route from the selected entry segment to the selected exit turn arrow will be disabled

If there is only one route available in the junction box then the switch route selection will not appear. Note it may take several clicks to get to the desired route.

Example of the route selection in a situation where there are some alternate looping routes available. The first picture shows the typical green path for eastbound Franklin St NE as it continues across Rhode Island Ave NE. If the straight path was prohibited by a Jersey barrier and signage, then the editor can select the alternate path of southbound 15th St NE to northeast-bound Rhode Island Ave NE to eastbound Franklin St NE. The second route as shown in the second picture was set up by clicking the Route icon six times and then allowing the junction box's turn restriction.

          

Using the same example the first picture below shows the typical green path for eastbound Franklin St NE as it continues across Rhode Island Ave NE. Disabling the path path of southbound 15th St NE to northeast-bound Rhode Island Ave NE to eastbound Franklin St NE will disable all paths for eastbound Franklin St NE through the junction box. Which is not the same as allowing the green path for eastbound Franklin St NE as it continues across Rhode Island Ave NE.
