Collecting traffic data is a critical piece of advancing transportation projects. Intersect, VHB’s latest technology-driven innovation, revolutionizes the way we view traffic movements across all roadway types on the transportation network, leveraging big data and traffic analysis to provide data-driven, trusted results. Intersect combines data from multiple sources to present a comprehensive coverage of the network capable of delivering traffic counts, turning movements, and origin destination studies while uniquely using existing count data as controls to further enhance accuracy and incorporate investments agencies have already implemented in the field.
Turning Movement Counts (TMC)
As a transportation planning tool, Intersect uses big data to review probe information obtained from cell phones and connected vehicle technology to develop intersection traffic volumes and turning movement counts without the need of traditional field deployed devices. Using individual trip path information allows Intersect to successfully account for vehicular volumes at urban, suburban, or rural intersections, along with the ability to provide year-round availability.
Intersect provides what a typical Automatic Traffic Recorder (ATR) or camera or manual counts would calculate but expands to include and determine Average Daily Traffic (ADT), or Annual Average Daily Traffic (AADT), and identify hourly trends and peak periods of travel. The use of control points from deployed devices and detection systems further enhances Intersect abilities to leverage investments made by agencies while providing coverage on all roadway types in a network regardless of classification.
Origin & Destination
Intersect has the ability to provide Origin and Destination (OD) information across the transportation network, including how travelers are moving on the network, the roadway paths that are taken, and how conditions on the network impact traveler decisions.
Intersect provides users the ability to use probe data to deliver detailed 24/7 travel times, roadway speeds, and congestion hotspots, avoiding the need to conduct these studies in the field.
