There are five methods to control traffic flow:
- Mega event - A major event that will typically have road closures or detours. It is usually a scheduled event with significant exposure and likely to impact an entire community. A major natural disaster can be added after it occurs if roads are going to be rerouted for many days.
- Road Closures - Road Closures can be enter in WME, or through the client as you drive by them. Details about entering closures through the client are covered in the next bullet point item. The Road Closures Form (USA) (or a similar form for your country) is to be filled for closures related to construction, work closures and emergency closures. This form is to be used by all editors who do NOT have direct access to the Waze Road Closure system. US Champs and State Managers will review requests entered and will be submitted to Waze if approved. Other countries may have a separate Road Closure Form.
- Temporary road closures - Users in the client app can mark an unexpected road closure they see while driving. It is typically used for unexpected, short term closures of a few days. Currently this feature is only available in the client application and requires multiple users be at the location to enter the same road closure information on the map before it will be seen by other drivers. Once this feature is available in WME it will have more use.
- Partial restrictions - AKA Scheduled or Time-Based Restrictions. Used when turns or roadways are restricted for certain times of day, days of the week, vehicle types, etc. It has the ability to only restrict during a specific date range, so it can be used in place of mega events or temporary road closures if necessary (as a last resort).
- Disconnect road segments - Road segments should only be physically disconnected if the road is no longer intended to connect or is being permanently removed. In the past, this method was used for longer term construction projects, but now the Road Closure feature should be used.
