Traffic Prediction
The Traffic Prediction feature of IBM® Intelligent Operations for Transportation provides traffic prediction capabilities for transportation authorities. The Traffic Prediction feature uses the historical and real-time traffic data that is collected by the Traffic Awareness system to predict future traffic levels of a geographical area, up to an hour in advance.
Traffic Prediction is an optional feature that enhances the IBM Intelligent Transportation solution by providing the following benefits:
- Geographical visibility of predicted traffic levels at selected time intervals ahead of the current time up to one hour ahead of the current time. For example, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, or 60 minutes
- Listed view of details that are related to the predicted traffic levels at selected time intervals ahead of the current time, as selected with the Prediction interval slider. For example, 5, 10, 15, 30, 45, or 60 minutes
- Executive reports for traffic prediction that are based on speed and volume
- Accuracy reports analyzing traffic prediction data
The Traffic Prediction predictive analytics perform estimate and mean calculations that are required by the algorithm to generate near future traffic levels. Three months of historical traffic speed or volume data is required for the generation of future traffic levels.
The following table describes the detailed subsystems that are provided by the Traffic Prediction feature.
| Subsystems | Provides |
|---|---|
| Predictive analytics | Complex algorithms and processes that generate predictions of the traffic levels of a geographical area, one hour from the current time. The predictions are based on historical traffic speed and volume data from the previous three months. You can also provide the holiday data for your transportation network to further improve the accuracy of the predicted traffic levels. |
| Traffic prediction visualization | Processes and a graphical user interface to display the traffic prediction data. The predicted traffic levels are displayed on a GIS map and a table. |
| Traffic prediction reports | A graphical user interface to analyze and display summary reports of traffic predictions. The reports are based on speed and volume. |
| Accuracy reports | A graphical user interface to analyze and display reports that summarize the accuracy of traffic predictions. |
| Administrative and operational interfaces | A browser-based graphical user interface that includes an administration view to facilitate traffic prediction. The interface also includes role-based administrative features, providing the capability to configure traffic prediction settings so that it can correctly operate within a particular customer environment. The Traffic IT Administrator has the permission to configure the settings for the traffic prediction calculations in the Administration view of the solution interface. |
| Programming and client interfaces | REST services that provide outbound subscription and publishing capabilities to retrieve current and predicted traffic data from the solution into XML format. Extends the LinkStatus REST service that is provided by the Traffic Awareness feature. |
The information from the traffic management subsystem is presented in the IBM Intelligent Transportation portal solution interface. The Operator: Traffic view displays the current and the forecasted traffic situation.
