The Detector Ingestion API provides an endpoint to submit raw detector measurements for a PTV Flow product instance.  The submitted measurements are validated, archived, and forwarded for …

Partial batch acceptance: valid and invalid items A System Integrator (SI) submits a batch where some measurements are valid and some are not (for example, a detector code that does not exist, or a reserved field set to a non-null value).  The service …

Partial batch acceptance: high volume ingestion A System Integrator (SI) submits a batch of 20.000 measurements. Due to the volume of the batch and the limit of the architectiure, the processing budget is exceeded after validating 14.000 items. The …

You can use the Detector Ingestion service to implement standard batch ingestion of the measurements associated with the detectors in your Flows instance. A typical scenario is a client application (for example, a telemetry system) that provides a …

Add two detectors to a count location associated to a count site The System Integrator (SI) creates a sensors network. First step In one only payload the SI can build the entire hierarchy of count sites, count locations and detectors. In this use case, in …

With the Detectors service you can get several types of measurements from the field of your instance. Follow the steps on this page to get started with Detectors …

Add a vehicle type The System Integrator (SI) needs to add a new vehicle type. First step As starting point, it is necessary to check which vehicle types are associated to your instance. GET …

The Detectors API can be used to build a count site capable to register several types of real-time data. A count site represents a logical object (such as an intersection or a parking facility)  where speeds, flows, counts, etc. are measured using …

KPI instance  A KPI instance is described by a set of attributes: KPI identifier: unique alphanumeric string associated to a KPI instance.  Example: "kpiId" : "a5c22445-8592-430b-b36b-01d265a996d0" KPI name: string associated with a KPI instance. KPI …

How to show the travel times forecast at +30 minutes The use case reflects the common need of a system integrator that must show of forecast results at +30 minutes on the GUI the layer. GET https://ptvgroup.tech/mlf/v1/forecast/realtime The result is an …

Tiles  In the context of a traffic network map, a tile is a small square segment of an image or vector data that makes up a portion of a larger map.   Instead of downloading a single, massive image of the entire road network, modern mapping systems divide …

How to create alerts associated with a KPI value  The use case is focused on the creation of alerts associated with KPI values.  The KPI values can be compared with two different thresholds identifying a WARNING level (YELLOW) and a CRITICAL level (RED). …

How to create a KPI When you create a KPI, you are creating a "location" associated to a "shape". The building of a shape is based on the format Well Known Text (WKT).  Each WKT object follows a fixed structure. The most common structures are: Point: …

With the Street Forecast service you can get forecast measurements of different dimensions of the traffic network. Follow the steps on this page to get started with Street Forecast …

The KPI service allows you to define several measurements to assess real-time characteristics of the traffic network. More specifically, you can handle: The current KPI value Partial KPI values on specific links of the corridor Follow the steps on this …

Key Performance Indicators (KPIs) are used to assess, monitor, predict, and give alerts on specific corridors based on different characteristics of the traffic. KPI API is specifically designed to provide in-depth insights into the performance of defined …

How to get a KPI for a corridor over a specific time range The use case is focused on getting KPI data on a specific corridor,  over a specific time range, to analyse performance metrics and understand trends and patterns over specific time periods. First …

How to get a specific day and hour for the entire network (snapshot in the past) The use case is focused on getting the measured speed and flow data for the entire network at a specific date and time in the past. You can therefore understand what happened …

How to get a specific data time series for a specific network element The use case is focused on getting a speed time series for a single network segment, over a specific time range. This endpoint can be used to monitor the performance on that segment to …

The PTV traffic volume API provides traffic volumes for various time periods and vehicle segments for a specific location  (x,y coordinate) and a buffer around the location in Germany and France. All traffic volumes are available for the following vehicle …

OpenLR™ is a standard for handling map locations.  It is designed to transfer location information between different traffic management systems, using dissimilar maps. The encoded locations are typically specific road stretches, lists of connected roads, …
