![]() ![]() The traffic map service can be used with ArcGIS Maps SDK for JavaScript to create fully customized web mapping apps or with ArcGIS Maps SDKs for Native Apps to build app for desktop and mobile devices. The traffic map service is a dynamic map service built on ArcGIS Server technology, so functionality that is listed in the Map Service topic is available with the traffic map service. See the Create apps from maps topic to learn about the ways you can develop apps using web maps. ![]() You can add other operational layers to the traffic web map and create your own web map or a web mapping app using the configurable templates available from ArcGIS Online. The web map includes a streets basemap for reference as well as preconfigured pop-ups for point features that provide additional information about the incidents. Work with the traffic web mapĪ traffic web map is available in ArcGIS Online that can be used to create browser-based and device-based apps that require traffic visualization. The minor and low impact values indicate incidents that have progressively less impact as compared to incidents with the major value. The critical value indicates a road closure, and major indicates a blockage of multiple lanes. The Severity field in the traffic incident layers can have the following values: The IncidentType field in the traffic incident layers can have the following values: Red (stop and go)-0 to 45 percent of free flow speeds.Orange (slow)-45 to 65 percent of free flow speeds.Yellow (moderate)-65 to 85 percent of free flow speeds.Green (fast): 85-100 percent of free flow speeds.To travel when unencumbered by other vehicles. Speeds, which is typically the speed limit or how fast cars tend Traffic speeds in the service are displayed as a percentage of free-flow The traffic incidents are not archived and are refreshed with every update. This allows you to visualize traffic speeds within an 8-hour time window. The service archives the traffic information for up to 4 hours. This allows you to visualize traffic for future planning. Each traffic update also includes traffic speed predictions for the next 4 hours. The traffic data used by the service is updated every five minutes. If you want to emphasize why a particular route was returned by the route service, you can display the traffic map along with the route to show areas of traffic congestion that influenced the choice of roads used by the route. The traffic data used by the traffic map service is also used by the Routing services when performing analysis. The traffic map service acts as a good background layer to display the results from Routing services. The traffic speed and incident data is updated every five minutes. The traffic incidents in the map service provides the location of the incidents and some attributes such as the severity, the expected start and end time, as well as the description of the incident. ![]() Traffic visualization displays information about how travel speeds on specific road segments change over time. You can use the traffic map service to visualize real time traffic speeds and incidents such as accidents, construction sites, or street closures. ![]()
