TrafficCast International and LandSonar Introduce LPS Plus to Support Trip Planning and Resource Deployment with Integrated Historical Speed Data


Madison, WI-- TrafficCast International, Inc. the leader in real-time traffic data analysis and LandSonar, the leading supplier of full coverage highway speed trends, announce the product launch of LPS Plus, an enhancement to LandSonar Predictive Speed (LPS™).

LPS Plus offers a unique historical traffic speed data set for LBS and GIS applications, an integration of the two largest historical traffic flow databases in the traffic industry. TrafficCast has archived public sensor data for the last ten years while LandSonar has developed speed trends from GPS probe data over the last five years. In combination, LPS Plus offers increasingly accurate data for efficient route planning and improved trip time estimation. LPS Plus projects historical speeds to the link ID and traffic code level for digital maps of major roads throughout the United States, 450,000 miles of roadway coverage defined in 15 minute increments.

This enhancement to LPS, the industry-leading historical road speed aggregation product, also addresses anomalies and data gaps that result from the source GPS probes. TrafficCast fills these gaps with proprietary technology integrating its own archive of historic traffic data, collected from a variety of public and private sources. The result normalizes historical speed data output for precise resolutions of digital mapping and routing applications.

Since 2001, LandSonar has collected billions of open and proprietary historic GPS observations to develop highly accurate historical traffic speed information for the continental US. TrafficCast aggregates real-time information from over 350 US data sources, and provides nationally normalized data feeds and sophisticated traffic impact modeling tools for 180 markets. TrafficCast International technology was recently deployed in the world’s largest cell probe system in Shanghai. The companies’ offerings interoperate with the commercial mapping data of both NAVTEQ and Tele Atlas.

This integration of data sets is a further extension of previously announced agreements between LandSonar and TrafficCast to develop advanced traffic flow products for customers in traditional and interactive media, fleet management, and the public sector.

“This enhancement to our core LPS product will further enable our clients and partners to achieve precision in their LBS and navigation applications,” said Jonathan Hubbard, CEO and co-founder at LandSonar.

“TrafficCast International is pleased to add our core traffic engineering experience and archived traffic flow data to enrich the already strong LPS product. Our relationship with LandSonar is paying increasing dividends, and this is just one example,” said Connie Li, CEO of TrafficCast International.
