Like almost everything else the world of construction, the world of project planning is increasingly moving toward processes that draw upon data—including what is often referred to as “big data,” which holds keys to spotting large-scale shifts in communities.
One planning tool traditionally used to validate proposed projects is the interview-based travel survey, or trip matrix report. These studies capture patterns in where and when people move. The data can hold valuable information about the people in a certain area. But too often, and often too late, developers realize that the data used in the planning phase was grossly inaccurate, and as a result, millions of dollars are lost on projects that weren’t feasible in the first place. Add in dramatic fluctuations in demand as buyers becoming renters, office workers start working from home, etc., and the challenge to forecast population and traffic shifts becomes even more daunting.
But today there is a new approach to generating trip matrix data. Mobile devices are the new frontier.
"Communications and transportation are two staples of the economy. Our ability to provide insights allows us to contribute to a more efficient transportation system; it’s our corporate responsibility and ingrained in our culture."

For the first time in history, U.S.-based transportation planners and traffic engineers have access to insights into how their peers view the industry, their organizations, private vs. government jobs, gender and age issues and more.
Other findings featured in the research include:
Perspectives on government entities vs. private corporations
Views on technology and how innovative the industry is
Insights into how transportation planners view budget challenges and bureaucracy
The future of housing, infrastructure, transportation planning, urban/suburban sprawl and more...
In a recent paper--named a “Best Paper” at URBCOMP 2013--scientists at Massachusetts Institute of Technology detailed their research to make cities ”more livable, more efficient, and better positioned for the centuries ahead.” The foundation for the research was to establish reliable estimates of when and how 1 million residents use Boston-area facilities. AirSage data provided this insight, providing what the paper called an “improved ability to capture, store, and understand how massive amounts of data is changing the methods for inferring human behavior.

One of the biggest convcerns about VMT is privacy and how to protect it. But a solution may already exsist. Cy Smith, Founder & CEO of AirSage, explains in an article that appeared in Transportation Issues Daily and The Daily Transportation Update (AASHTO daily newsletter) "Could This Be a Solution to VMT Privacy Concerns?"
...some startups are building businesses by aggregating this kind of data in useful ways, beyond what individual companies may offer. For example, AirSage, an Atlanta company founded in 2000, has spent much of the last decade negotiating what it says are exclusive rights to put its hardware inside the firewalls of two of the top three U.S. wireless carriers and collect, anonymize, encrypt and analyze cellular tower signaling data in real time.
Since AirSage solidified the second of these major partnerships about a year ago (it won't specify which specific carriers it works with), it has been processing 15 billion locations a day and can account for movement of about a third of the U.S. population in some places to within less than 100 meters, says marketing vice president Andrea Moe.
As users' mobile devices ping cellular towers in different locations, AirSage's algorithms look for patterns in that location data - mostly to help transportation planners and traffic reports, so far. For example, the software might infer that the owners of devices that spend time in a business part from nine to five are likely at work, so a highway engineer might be able to estimate how much traffic on the local freeway exit is due to commuters.

The ability to collect users' geo-loco data is becoming extremely valuable. On an individual level, it allows targeted advertising based on where the person is situated or is predicated to. Moreover, the information can be aggregated to reveal trends. For instance, amassing location data lets firms detect traffic jams without needing to see the cars: the number and speed of phones traveling on a highway reveal this information. The company AirSage crunches 15 billion geo-loco records daily from the travels of milions of cellphone subscribers to create real-time traffic reports in over 100 cities across America...

A global team of researchers have combined the most complete record of daily mobility, based on large-scale mobile phone data, with detailed Geographic Information System (GIS) data, uncovering previously hidden patterns in urban road usage. We find that the major usage of each road segment can be traced to its own - surprisingly few - driver sources. Based on this research, they propose a network of road usage by defining a bipartite network framework, demonstrating that in contrast to traditional approaches, which define road importance solely by topological measures, the role of a road segment depends on both: its betweeness and its degree in the road usage network. Moreover, their ability to pinpoint the few driver sources contributing to the major traffic flow allowed them to create a strategy that achieves a significant reduction of the travel time across the entire road system, compared to a benchmark approach.

In the National University of Singapore, Institute of Real-Estate Studies Working Paper Series, researchers used mobile-phone traces as a data source for urban-modeling as opposed to traditional methods data collection, like traffic surveys. AirSage mobile-phone data allowed for “lower collection cost, a larger sample size, higher update frequency, and a broader spatial and temporal coverage” (see page 3). Finding useful insight on intra-urban mobility patterns, which is crucial to their research, was accomplished through AirSage’s Wireless Signal Extraction Technology.

IBM and participants from MIT investigate the use of mobile phones as a study platform for location data and group travel histories with the help of AirSage data to replace the use of dedicated GPS systems due to the “serious reliability and management issues” associated with their use (see page 3). They concluded that the use of GPS data was “not necessarily any more accurate than those produced by AirSage’s passive ‘Wireless Extraction’ system” which is why the use of smartphones is so important for their kind of research: “because such phones tend to be in near-constant contact with the network (to check for new email, to browse the web, download updates, etc.) they generate detailed traces that can be used to construct path histories with high fidelity across long periods of time.” (see page 19)

“Mobile phone technologies can produce audience measurements that are more credible than current static measurements and can reasonably expect that credible audience measurements will make it possible for outdoor advertising to reach its full potential in the future.” This conclusion was come to by Pervasive Reasearch group when they set out to create a system for measuring the audiences of outdoor advertisments. Through AirSage they were able to use mobile phone location estimations as one of their primary research methods and reach a conclusion for their results.

MIT SENSEable City Lab-Estimating Origin Destination Flows Using Opportunistically Collected Mobile Phone Location Data from 1 million Users in the Boston Metropolitan Area
In October 2011, MIT SENSEable City Labratory proved that “pervasive datasets, such as mobile phone traces provide rich information to support transportation planning and operation” (see page 9). They claimed that estimating a population’s travel demand in terms of origins and destinations of individual trips through mobile phone data would be a critical component of transportation management and emergency response. The lab’s analysis of 829 million mobile phone location data for 1 million devices was made possible through the AirSage Wireless Signal Extraction technology, which not only allowed them to ID the cell tower each mobile phone was connected to, but also gave them an estimation of its position within a cell.
