Signals from your Cellphone Tracked on Metro - WTOP (June 22, 2013)

WASHINGTON -- The half-dozen people standing on the platforms for a few hours may not have stood out, but they were actually carrying sensors that tracked Metro passengers moving through Fort Totten Station based on signals emitted from the passengers' pockets.Metro hopes the company's data analysis, which is not yet complete, could help provide better information about how people move through the station, how long trains remain at the platform, how long passengers have to wait, and whether people prefer to transfer between the Green and Red lines at Fort Totten or at Gallery Place.

Washington Metro Bluetooth Data Collection Pilot (June 2013)

Metro, in conjunction with Traffax, Inc. recently hosted a Bluetooth traffic monitoring test at Fort Totten station.  Bluetooth technology has been used for years now, for monitoring vehicular traffic. Specifically, it has been used to provide travel time and origin-destination data, mostly in vehicular settings.(More)

 Demonstration of Automatic Crowd-Metrics Measurement Technology at the Sakura Matsuri 2012 Festival

Travel time reliability--which is increasingly important to highways, arterials, transit, and air travel--is also important to pedestrians. When managing large crowds, performance measures relating to volume, density, and trajectory of pedestrians (crowd metrics) are essential. PRISM (PRoximity Information System for Mobility), which was developed in SHRP 2 Reliability IDEA Project L15B (Proximity Information Resources for Special Events), gives event organizers the ability to automatically measure crowd metrics. PRISM uses detectors that sense Bluetooth devices, such as cell phones, to identify the location of pedestrians. Software is then used to aggregate this data with data from Twitter and FlickR, and display the size, movement, directionality, and density of crowds in near real time. The potential uses for these crowd metrics include emergency management and deployment of event staff. This video showcases a demonstration of PRISM at the Sakura Matsuri 2012 Festival in Washington, D.C., which was conducted in cooperation with event organizer, the Japan-American Society.  

  BluFAX to support INRIX Traffic Quality Assurance Program

In the I-95 Corridor Coalition’s Vehicle Probe Project (VPP), INRIX has been and continues to be subjected to the most extensive and longest continuously running independent quality validation of private sector traffic data in the world. INRIX is now partnering with Traffax to offer to its other public sector customers the same quality and performance regime.

Traffax BluFAX Bluetooth sensors have been used by the University of Maryland since July 2008 to monitor INRIX freeway data quality for the I-95 Corridor Coalition Vehicle Probe Project (VPP) and has set the standard for quality control for outsourced traffic data.  Vallidation for the VPP involved analysis of numerous facilities 24 hours a day, 7 days a week, under a wide variety of operating conditions including light to severe congestion, holidays, snow storms, overnight work zones, all seasons, daytime and nighttime, weekdays and weekends. To date, data has been collected and published on a nearly monthly basis at 35 test sites in 8 states, producing a total of more than 41,000 hours of ground truth data across more than 750 miles.

SBIR firm develops tools to accurately measure travel time and arteria...

Through a Small Business Innovation Research (SBIR) award from the U.S. Department of Transportation’s Federal Highway Administration, Traffax Inc. developed and deployed a system of 48 real-time BluFax BluetoothTMTraffic Monitoring (BTM) sensors on major freeways and signalized arterials in Northern Virginia and suburban Maryland in 2011.

The focus of the SBIR project was to bring high-resolution BTM data to real-time applications for use by operations, traffic, and other purposes. The 48 unit deployment has been in full operation for over six months, providing high-resolution travel time data in real-time travel, sampling approximately one in twenty vehicles from these heavily traveled corridors.

Dulles Airport Backtracking and Cut-Through Assessment Study

BluFAX was selected for use on the Dulles Airport Backtracking and Cut-Through Assessment Study being performed by VHB and FreeAhead. Dulles International Airport is served by a toll facility. Roadway within the airport provide mean to bypass part or all of the toll, causing revenue loss to the authority.  Traffax deployed 14 portable BluFAX data collection devices for one week duration.   Traffax analyzed the data and provided estimates of the volume along the five backtracking and four cut-through routes that were identified by the airport as concerns. 

Pennslyvania I-95 Origin/Destination Study

Traffax was pleased to work with PB Americas in Pennsylvania on this project to collect and analysis origin-destination data needed to support regional modeling efforts. Traffax collected, analyzed, and delivered OD data for 38 interchanges along approximately 50 miles of I-95. Traffax deployed 146 solar BluFAX units for a period of 28 days. All units were configured to enable internal cellular modem and data reporting communication. Our BluSTATS software was used to generate travel time data, by hour for all segments along I-95 in both directions for the entire study period. Analysis for each interchange provided detailed information for each movement associated with that interchange. In addition, large-scale, project-wide trip matrices were developed for average weekday AM and PM peak periods, and specific hours on the weekend. Analysis performed by PB confirmed that 18% of traffic during peak periods was captured by BluFAX.

Saddle up with Bluetooth: MTO First in Canada to use Bluetooth for Travel Time Monitoring

In 2010, the Ontario Ministry of Transportation (MTO) was the first in Canada to deploy these units for traffic delay compliance monitoring. Allowable traffic delays are included in the Performance Specifications of MTO’s new Design-Build Contracts, which describe the maximum length of time a contractor may delay traffic travelling though a construction zone.

S.R. 23 Origin Destination Study Utilizing Bluetooth Technology

Resource Systems Group used BluFAX to support a recent study commissioned by the Florida Department of Transportation.  The objective of this project was to identify the current traffic patterns on S.R. 23 in Jacksonville, FL in response to recent changes to the corridor including a new interchange at I-10 and a new intersection at Plantation Oaks Boulevard. FDOT is evaluating plans to upgrade and toll S.R. 23 between I-10 to the north and S.R. 21 to the south. The future tolled facility will feature four lanes along the entire 15 mile corridor and use electronic toll collection transponder technology. This study aimed to capture the major travel movements along S.R. 23 and provide insight into the average travel speed conditions experienced by travelers. RSG coordinated with FDOT to identify 14 main travel movements along the corridor which needed to be updated in the travel demand model. RSG proposed using the Bluetooth technology due to the time and cost savings vis-à-vis traditional data collection methods. Further, the study demonstrated that the quantity and granularity of the data is far greater than other methods which allows for more robust analysis.

US Canada Border Wait Time Project

The "Effort to Test, Evaluate and Deploy Technologies to Automate the Measurement of Real-Time Border Wait Times at United States – Canada Land Border Crossings," is designed to develop an automated process for collecting border wait times that will be facilitated by the use of existing or emerging technology. This effort is sponsored by the bi-national, multi-agency Border Wait Time Working Group (BWT-WG) comprised of representatives from US and Canadian Transportation and Customs agencies and is supported by stakeholders that operate at or near the border.

The results of Phase I of the project are summarized in a TechBrief published by FHWA. Finding from Phase 1 were that at least two of the technologies showed significant promise and warrant further deployment testing: Bluetooth and GPS/smartphone. Traffax is pleased to participate in the Phase 2 of this project. Details are available from a Technical Brief published by the FHWA.http://ops.fhwa.dot.gov/publications/fhwahop11025/bwt_techbrf.htm

Chandler AZTravel time information project named ‘Best of  ITS Implementation Project of the Year’

A travel information project using electronic message boards on three of Chandler’s busiest commuter routes has been recognized by the Intelligent Transportation Society of Arizona as the Best ITS Implementation Project of the Year The Society presented the award to Chandler at their annual conference held September 26-27 in Mesa. The City, in partnership with software developer OZ Engineering of Phoenix and TPA-North America Inc, effectively integrated several new and existing technologies to display travel time information on large electronic message signs.

Traffax BluFAX Sensors accurately capture travel times along arterial streets leading to the freeways. “Being the first project of its kind in the U.S., it took a lot of coordination and problem solving between the makers of the Bluetooth units, the makers of the electronic signs, and the freeway speed data collected by the Arizona Department of Transportation to automatically generate these travel times,” said Mike Mah, the City Transportation Engineer overseeing the project.
