1	Integrating Clarus Data with the 511 New York Traveler Information System Road Weather Management Stakeholder Meeting September 8^th, 2011
2	Agenda Project Background & Goals Inputs into Road Segment Alerting Why is Clarus Data Important? About 511NY Demonstration Scenarios Observations and Results Next Steps Questions?
3	Project Background Project part of the Federal Highway Administration (FHWA) Broad Agency Announcement Research on Clarus System Data Winter/Spring 2010 Solicitation Number DTFH61-10-R-00015 “…develop new or improved road weather management/operations procedures, create innovative user interfaces, and develop new applications including weather-responsive traffic management tools.”
4	Project Background
5	Project Goals Collect and integrate Clarus observations and disseminate road-segment alerts for use in the New York 511 system and Connected Vehicle Program
6	Road Segment Alerting Inputs
7	NYSDOT Road Network Project coverage – Two New York transportation corridors
8	Road Segment Alerting Inputs
9	Road Segment Alerting Inputs
10	Why is Clarus data valuable for Road Segment Alerting? Alerting on observations from Airports… Typically 1-3 miles (or more) from a major roadway Report atmospheric (non-roadway) variables only Air Temperature, Wind Speed & Direction…
11	Why is Clarus data valuable for Road Segment Alerting?
12	Clarus Stations Used
13	Clarus RWIS versus Roadway Radius of influence around the RWIS selected from Clarus 8 miles

30	From the Traveler’s Perspective
31	From the Traveler’s Perspective
32	Observations & Results Both NYSDOT and FHWA evaluated the pre-production 511NY system over a 3-month time period. Alert Prioritization Standardize order of alerts to display (radar versus warnings, etc.) Data Quality RWIS data quality is key to ensure data can be utilized for alerting Information Clarity Keep public perception/interpretation in mind…keep it simple Provide additional information on alert types Standardize the colorization and terminology Cease use of Flood Warnings…keep Flash Flood Warnings Thank you NYSDOT & FHWA!
33	Next Steps Simplify and clarify the alert results
34	Next Steps Simplify and clarify the alert results Explore integration of road segment alerts into 511NY production system
35	Next Steps Simplify and clarify the alert results Explore integration of road segment alerts into 511NY production system Integrate road segment alerts into the NY Connected Vehicle program
36	Other Uses for Road Segment Alerting XML feed can be integrated into many different applications Connected vehicle initiatives 511 programs Traffic Management Centers Traffic modeling input Signal timing
37	Thank You
