Examples of Weather Integrationin TMC Operations

McFarlandManagement, LLC


in TMC Operations• Increased internal weather information resources (e.g.

camera imagery, use of satellite and ASOS data, etc.)• Increased use of external weather information and forecasts• Expanded availability of weather information • More frequent weather forecasts (occasional to continuous)• Use of more road weather observations

Level 1 Cable channel or subscription weather information vendor providing general weather information

• Greater coordination of weather information within TMC, with maintenance, meteorology staffM t i th

Level 2 Internet provided weather radar or satellite image on video wall

Level 3 Field observers or ESS network providing scheduled road or driving • More extensive weather coverage• Closer association with weather experts

Automated weather alert notification

condition reports

Level 4 Vendor provided daily surface transportation weather forecasts and observed weather conditions

5

• Automated weather alert notification• Greater use of decision support systems (such as MDSS)

observed weather conditions

Level 5 Meteorologist, located within TMC, forecasting and interpreting weather

Integration Activities with TMCsMcFarland


Management, LLC• Sacramento, California Regional TMC: Implemented and evaluated the performance of a weather alert notification system

• Kansas City Scout TMC: Integrating weather event forecast• Kansas City Scout TMC: Integrating weather event forecast information into their Advanced Traffic Management System (ATMS)Colorado Springs TMC: Conducting a pilot study on winter• Colorado Springs TMC: Conducting a pilot study on winter weather arterial signal timing in one of their city grids

• Louisiana statewide TMCs: Completed a comprehensive statewide self-evaluation and integration plan across their four TMCs

• Wyoming Statewide TMC: Expanding road weather information y g p gsensor coverage and implementing additional variable speed limit notification system in key corridors

• Redding, California TMC: Completed their self-evaluation but

CLARUS INITIATIVE8

CLARUS INITIATIVE

The Clarus InitiativeMcFarland


Management, LLC

•Clarus is an R&D initiative to demonstrate and evaluate the value of “Anytime, Anywhere Road Weather Information” provided by both public agencies and the private g pweather enterprise to transportation users and transportation users and operators.

What is Clarus SystemMcFarland


Management, LLC

• “Robust data assimilation, quality checking, and data dissemination system that could provide near real-time atmospheric and pavement

fobservations from the collective state's investments in road weather information system, environmental sensor stations (ESS) as well as mobile observations from Automated Vehicle Location (AVL) equipped trucks”trucks

for current road weather information.• Accuracy/Precision – The “closeness” between an

observed or forecasted condition and the actual condition;observed or forecasted condition and the actual condition; • Completeness – Whether there was adequate information to

fulfill users’ requirements;• Relevance – The fit of the information to the users’ needs • Currency/Latency – The age of the information;• Timeliness/Reliability – Whether there was consistent and

on-time delivery of information; and• Ease of Use Whether it was easy to obtain interpret and• Ease of Use – Whether it was easy to obtain, interpret, and

Data Mining and Gap AnalysisMcFarland


Management, LLC

• Conduct a comprehensive search and documentation of traffic and weather data in the United States and abroad thattraffic and weather data in the United States and abroad that could be used for WRTM

• Establish contacts with organizations that have suitable traffic d t i l t th d d t idata on inclement weather and determine procedures/requirements to obtain these data;

• Identify critical gaps in regards to the collection and y g p gprocessing of traffic data on inclement weather conditions

• Recommend strategies and generate guidelines for gathering and processing data that will be used in WRTMgathering and processing data that will be used in WRTM studies.Report: Data Mining and Gap Analysis for Weather Responsive Traffic
