Integration of Low-Cost Sensors with UTMC for Assessing Environmental Impacts of Traffic in Urban Area
Recorded Presentations from the meeting are now available. A folder icon represents that recordings are available for at least one presentation in the session.
Purchasing Recording Access: ITS America is now offering the option to purchase whole meeting or track access to the recordings if you were not a full registered attendee of the meeting. You may Purchase Full Meeting Access or you will have the option to purchase just individual track access. If you want to purchase multiple tracks, you will need to browse to a recording in each track to purchase that individual track. Full registered meeting attendees still have free access using their registration credentials. Please email email@example.com if you need your registration credentials sent to you.

Description of Paper:
A new generation of low cost wireless pervasive sensors (Motes) has been integrated with UTMC to evaluate models which enable SCOOT, and provide complementary monitored data, to predict the impact of Traffic Demand Management Strategies on the environment in near real-time. The output from a dispersion model (OSPM) linked with a new emissions model is validated using data captured by the motes (measuring air pollution, CO, NO2 and NO) and legacy systems including SCOOT, AURN (Automatic Urban and Rural Network) and meteorological conditions. This validated model and/or the motes will then compliment legacy systems through their ability to cover detection gaps in existing urban networks. Accordingly in the absence of a legacy traffic system, the motes also can be deployed independently.
