Most Cost Effective Detection

Ten Reasons Roadrunner RF Is Most Cost Effective

Cost Comparisons

Sensor system comparability includes installation costs, maintenance costs, dissemination costs, and infrastructure costs. We have modified the Texas Transportation Institute’s “Detector Life Cycle Costs and Considerations” spreadsheet application to incorporate Roadrunner RF’s costs. It can be used to identify the relative cost of the technologies to one another, given different user‐inputs. A copy is here. Figure 1 shows the results. Additional cost considerations are listed below.

Low Software
Development Costs

;
These costs fall under the heading of time and money expended in developing, writing the software, revising, reviewing, piloting and field testing. We’ve spent a great deal of time, effort, and money on developing Roadrunner. It’s built on 30 years of experience in traffic and multimedia, and we’ve based the product on Open Source material. By using open source Roadrunner relentlessly drives down the costs. Roadrunner uses a custom build of Linux, Apache, PHP, Bash, MySQL, in-memory databases and Postgres and a large number of other open-source software projects. In Roadrunner’s scope of operation, open source hasn’t just caught up to proprietary solutions, it is leading the pack.

Low Material Costs &
Vendor Agnostic Hardware

Roadrunner is not [yet] another home-baked put together using the cheapest Power PC board and components the developers could find. The Roadrunner flagship system runs on an Intel™ NUC box, which packs the punch of a powerful desktop workstation into a tiny 1 1/4″ x 4″ x 4″ footprint. It has support for USB 3.0 and sports a Gigabit Ethernet port. Moreover, it is fueled by a Haswell Core i5 CPU, making it an extremely powerful device with Intel quality baked in. Roadrunner’s less expensive, Tier II systems run on Ubiquity PicoStations, which are known worldwide for providing inexpensive wireless service. We emphasize again, Roadrunner does not, like competitive products, use a 15-year-old Power PC technology and decades old software, it is a state-of-the-art system that utilizes the latest hardware, firmware, and software technology to deliver a quality matrix sampling product.

Short on Red Tape

The Red Tape associated with the installation of Roadrunner is minimal. Mount the NUC on the DIN rack in a traffic cabinet, penetrate the bulkhead with an bulkhead connector, Attach the antenna (preferably on a pole), snap in the RJ45 ethernet cable and power up the unit. It’s that simple. No pucks to install in the roadway, no need to shut down traffic to install loops. No special precautions for mounting a radar unit, no masthead cameras to install (or lenses to keep clean).

Low Installation Costs

Unlike other systems, such as video, radar, magnetometer, toll-tags and loops, installation of the Roadrunner RF system requires no special crews, training, or subcontractors. The system can be first set up in the TMC shop and sent to the field, or installed through local wireless connections or ethernet. As long as there is an antenna, ethernet or GSM connection, and a power supply, Roadrunner will perform.

  • Unlike magnetic sensors, there are no roadway holes to drill.
  • Unlike loops, there is no roadway installation.
  • Unlike loops and magnetic sensors, no disposal problem when it’s time to do a chip seal.
  • Unlike cameras, there are no lenses to clean.
  • Unlike radar, there are no positioning restrictions.

So, not only does Roadrunner cost less, it costs less to install.

Low Data Collection Costs

If fiber or an internet connection is available through the signal master cabinets, there is zero additional cost. Otherwise, the Intel® XMM™ 6255 modem platform combines the Intel® X-GOLD™ 625 baseband and its integrated power management unit with the Intel SMARTi™ UE2p – the first transceiver with a fully integrated 3G power amplifier. It can connect to Sprint, Verizon, and other mobile providers.

Reliable, Which Drops Costs

Everything boils down to data quality, and the truth is no one system efficiently provides everything needed. If the measure of success is considered to be delivery transit time between two measurement points, Roadrunner RF delivers in spades. Toll-tags can match this data quality, but toll-tag reading is expensive and the number of toll-tags on vehicles is much smaller than cell phones and in-car Bluetooth™. Radar and video can only render speed estimates at an intersection, and that is variable. Loops and magnetometers, to give accurate speed counts, require multiple installations. In terms of quality data per dollar, Roadrunner RF comes out on top.

High Data Validity for a Low Cost

How well does Roadrunner RF matrix sampling deliver transit times? Given a full signalized intersection install, the answer is very well. Such a system renders not only current status, but status compared to hour of day, day of week, week of month and month of year. It renders a more complete picture of the entire system, its performance, and where it can be optimized and improved.

Low
Reporting Costs

Roadrunner RF data collection structures its reporting in accordance with NTCIP standards 1206 and 1209, in addition to the Institute of Transportation Engineer’s Traffic Management Data Dictionary version 3.3.  This allows traffic centers to cooperate in the management of a corridors, arterials, incidents, and events. In addition, Roadrunner RF provides a User Interface/User Experience based on adaptive and responsive web technologies, which ensure that the product is appropriately displayed for pico, mobile, tablet, desktop, and multimonitor technologies.

No Recurring Costs
No Cloud Computing Requirement

Roadrunner uses a classical software update model. We have orderly revisions and discounted updates. We don’t require cloud computing, and we recognize there are many arguments against it:

  • Constantly changing terms of service;
  • Recurring service fees;
  • No central body for governing use;
  • No firm details on ownership of data.
  • No portability, among others.

If your operating model includes cloud computing, Roadrunner can accommodate it. If not, it isn’t a requirement.
