TRAFFIC DATA COLLECTION
BICYCLE DETECTION AND MULTI-MODAL TRANSPORTATION DATA In recent years, in response to demographic changes, healthy life- style initiatives, and increased environmental consciousness, there has been a greater realization that bicycling should be given con- sideration equal to other transportation modes in decisions about roadway design. VectorSense provides data on all types of vehi- cles, enabling engineers and planners to collect and analyze traffic data to optimize infrastructure investments such as bike lanes, bike paths, and bike share locations. The permanent nature of VectorSense Sensor installations allows
planners to track performance against mode share targets over time. As VectorSense Sensors also provide good data on vehicle position and class, they can provide important data on congestion, mode conflict, and opportunities to target redesign of roadways where safety is a concern. VectorSense Sensors use tire footprint sensing to detect bicycles,
offering greater reliability than inductive loops, which may not detect bicycles with non-metallic frames. VectorSense offers the potential to detect different bicycle types like tricycles or bikes with super-wide tires (fat bikes). Multiple VectorSense configurations can also provide volume, occupancy and speed data for all vehicle types.
VECTORSENSE SENSOR DATA REPOSITORY Data analysis software is a key part of the comprehensive system that uses VectorSense Sensors. A complete software analysis pack- age called Vehicle Information in Motion (VI2
M) is complementary
to the VectorSense Sensor Suite. The VI2M software displays graphic representations of each vehicle, much like IRD’s Virtual Weigh Sta- tions display for commercial trucks. An easy-to-use web-based system of dashboards that graphi-
cally represents data stored in a central repository is an integral part of VI2
M. In addition to tabular reports on vehicle classes and
axle counts, the system can generate plotted graphs for lane posi- tion, wheel measurements, and wheel type at multiple sites. Graphs generated by the system are interactive, allowing the user to mouse over data points to display counts for particular contact patches and wheel types. Finally, VI2
M is an enhanced traffic data system that functions
stand-alone or augments existing vehicle count, classification, and weigh-in-motion technologies with additional traffic data from VectorSense Sensors. It has many applications besides statistical and pavement design
inputs, including enhanced vehicle classification for toll operations, improved safety screening for commercial vehicles, and identifica- tion of tire anomalies. l
