Roadrunner RF

Smart, Inexpensive Detection & Analysis

1. Sensing Wireless Connections

Roadrunner RF detects Bluetooth™ and 802.11 wireless Local Area Network (Wi-Fi) connections on-the-fly at intersections. These signals are found on Apple iPhones  (4, 4S, 5, 5S, 5C, iPad (2, 3, 4, Air, Mini, Retina), all Android-equipped phones (Acer, Asus, HTC, HuaWei, LG, Kyocera, Motorola, Samsung, Sony and ZTE). Carriers for the phones include AT&T, Springt, T-Mobile, U.S. Cellular, Verizon wireless, and Virgin Mobile. In addition, wireless navagation systems, such as TomTom, nuvi, Magellan, and other in-car systems use wireless connectivity.

The 802.11a, 802.11b, and 802.11g components are based on a fork of work released in April 2007 by a team at the Darmstadt University of Technology in Germany, which in turn was based on a paper published in 2001 on the RC4 cipher by Scott Fluhrer, Itsik Mantin, Adi Shamir. Sampling time can be varied, as can the channels.

2. Data Aggregation

Roadrunner RF does not use the old SNMP standard for communication, but a more modern RESTful approach. Without embellishing on what the W3C standards for REST are, here is a quote from W3C itself:
With RESTful APIs and RESTful Web Services, clients use basic HTTP verbs, with their simple and direct meaning, to obtain and alter the state of objects on the server…

While we haven’t retained the SNMP protocol, the basic NTCIP structure is preserved, as demonstrated below in the linked files:

3. Data Analysis

Roadrunner currently uses a MySQL implementation and a PostgreSQL version. Our objective is to be the most cost effective RF traffic analysis tool on the market, so we have chosen open source products.


PostgreSQL (pronounced Post-gress-cue-ell) bills itself as the world’s most advanced open source database. Some of its fans say it is as good as Oracle, but without the baggage of high cost and snooty customer service. It has a long history, having been developed originally in 1985 at the University of California, Berkeley, as a descendant of the Ingres database.

PostgreSQL is a 100% community-driven open source project, maintained by a worldwide community of more than a thousand contributors. It provides a single completely functional version, rather than the multiple different community, commercial, and enterprise versions that MySQL offers. Its license is a liberal BSD/MIT-type, which allows organizations to use, copy, modify, and redistribute code with only a copyright notice required.

Documentation is first-rate, with comprehensive manuals available for free online, along with archives of manuals for older releases. Community support is excellent, and commercial support is available from independent vendors.


MySQL is relatively new, first appearing in 1994. It calls itself the world’s most popular open source database. MySQL is the M in LAMP, the software bundle frequently used for web development that also includes Linux, Apache, and Perl/PHP/Python. Most applications built on a LAMP stack incorporate MySQL, including such well-known applications as WordPress, Drupal, Zend, and phpBB.

Initially MySQL was designed to be a fast web server back end, using a fast indexed sequential access method (ISAM), with no ACID support. Since those lean, speedy early days MySQL has added support for a number of additional storage engines, and ACID compliance is now available via the InnoDB engine. MySQL also supports other storage engines, providing capabilities such as temporary tables using the MEMORY storage engine, an example for developers with the EXAMPLE storage engine, fast read-mostly databases using the MyISAM engine, plus several other core storage engines and a number of third-party engines.

4. Data Visualization & Presentation

We provide engineering professionals professionally engineered technical web interfaces that are both responsive and adaptive.

Responsive and Adaptive have loaded meanings here: they describe a software interface design that flows

  • into a multi-monitor system or a touch table in a control room,
  • adapts to an individual monitor,
  • works on a touch tablet, and
  • displays on a smart phone.


Maps programs include OpenStreetMap, MapBox, and GoogleMaps.

Finally, there are specialized, Beck Topological maps for even distribution of data points.
