Throwback Thursday – Who You Gonna Call? NoiseBusters!

Thursday, April 10th, 2014

Around 1987 or so Dave Towers won a job working for an elderly woman living on the West Coast of Florida who could hear a noise that was inaudible to anyone else. Ted Baldwin made Dave a custom “NoiseBuster” suit of equipment.

Bob Miller’s dad Laymon also visited the client and determined she couldn’t even hear someone clapping behind her back.  BUSTED!

The resemblance to Bill Murray is uncanny.  And we think Ted has aged better…

ACRP Report Released on Defining and Measuring Aircraft Delay and Airport Capacity Thresholds

Wednesday, March 12th, 2014

ACRP104coverLast week, the Transportation Research Board’s Airport Cooperative Research Program (ACRP) released Report 104: Defining and Measuring Aircraft Delay and Airport Capacity Thresholds. The ACRP report offers guidance to help airports understand, select, calculate, and report measures of delay and capacity. The report describes common metrics, identifies data sources, recommends metrics based on an airport’s needs, and suggests ways to potentially improve metrics.

Guidance and recommendations are provided regarding the relevance of particular delay and capacity measures by airport type, airport characteristics, and project lifecycle phase. The report suggests the most appropriate measurement tools at various points in the project development cycle, for specific items in each element, and for different types of airports. The report does recognize that it is not practical to have one threshold that can be applied to all airports.

The report includes additional metrics that would be helpful in the future, one of which is better communication of delays to the general public. The report summarizes that these communications should be easily understandable, able to be used as a common measure at any airport, and applied consistently across all airports. It was also noted that using a more positive metric, such as level of service, rather than using a term such as delay, which has a negative connotation, would better serve the public and the industry overall.

The research, led by TransSolutions of Fort Worth, TX, was conducted under ACRP Project 03-20. The other team members and primary authors of the report included Futterman Consulting of St. Petersburg, FL, Harris Miller Miller & Hanson Inc. of Herndon, VA, and Jasenka Rakas of Berkeley, CA.

Speed Networking in DC

Thursday, February 20th, 2014

by Ruth Anne Mazur

I recently attended a DC Chapter Young Professionals in Transportation (YPT) event that introduced me to something new.  In honor of Valentine’s Day, the group held a mock speed-dating event that was instead focused on speed-networking (#HighSpeedNetworking).  As someone who has never been speed-dating, I was a bit skeptical about how much fun it might be to meet people in this setting.  I thought it might be difficult for a group of engineers and transportation professionals to make short conversation with a few rounds of new people, and so were the event organizers.  At the beginning of the event, everyone enjoyed a joke regarding how long we should make the time interval and how we would “see how awkward the silence was after 2 minutes”.  I was part of the group that stayed seated, which was more comfortable in some ways, but did not allow me to move around to other tables with different appetizer plates. As the speed-networking got started, I was excited to see who I would get to talk to and how the event would flow.  What we found was that there was no awkward silence at all, and the interval was moved to 3 and then 4 minutes, with even that amount of time seeming to fly by.  Not only was it easy to make small chit-chat with everyone, but it was also great to learn more about each person and their type of work in the transportation world. In the end, I think everyone agreed this type of event was great for networking and gave us all the opportunity to get to know members of the organization better.  The purpose of the event was to talk to new people and find out what they were about, and this made it very natural (and fun) to meet more people in one night than one might at a typical networking event.  I believe this idea originated in the San Francisco chapter of YPT, and Kim Lucas, the YPT DC Vice Chair of Programs, brought it to DC with flair.

Thanks to Kim and YPT for holding such a unique and enjoyable event for transportation professionals in DC!

Centennial Airport Update

Thursday, October 31st, 2013

by Gene Reindel

The following link provides a well-written article featuring the installation progress of the noise monitoring system at Centennial Airport in Arapahoe County Colorado.  The progress is visible to the surrounding communities as 12 fixed noise monitors, installed to measure noise from aircraft operations, and is up and running.  The system installation is continuing over the next few months with full acceptance of the system expected in early 2014.  The purpose of the system is to provide much needed data to monitor the Centennial Airport aircraft noise environment and prepare highly accurate reports and noise exposure contours related to the aircraft operations at Centennial Airport.



Founder’s Award

At last week’s HMMH Annual Stockholder Meeting, the Founders of HMMH presented their award for excellence “In recognition of outstanding performance on a project that was uniquely challenging, technically innovative, and resulted in proven client satisfaction.”  The award was given to the project “On-Board Sound Intensity Measurements to Evaluate the Noise Reduction of Pavement Grinding, I-195, Providence RI.”  The Project Manager was J. Eric Cox, Principal in Charge was Christopher W. Menge, and the team included James E. Ferguson III, and Ryan Cranfill.

The purpose of the project was to prove that adequate sound reduction of I-195 road noise had been achieved by diamond grinding of the concrete bridge deck, mainline roadway, and on/off/interchange ramp surfaces. Grinding operations were conducted to reduce noise generated by traffic traveling over transverse tining. The “OBSI” measurements had to be made on 19 ramps and roadway sections, in the wee morning hours when little other traffic was using the roadways.  Client David Freeman of Maguire Group, Providence, RI said that “it worked out really well and the results [of the measurements] were used to justify a bonus to the contractor.”
