Specifying Solar Rectangular Rapid Flashing Beacons: Key Factors for Reliable Performance
Rectangular Rapid Flashing Beacons (RRFBs) are becoming an important part of the toolkit and a top choice for transportation professionals looking to improve vehicle yields rates, pedestrian service levels, and multi-modal transportation access at uncontrolled, marked crossings.
When Yellow Means Stop: Deciphering RRFB Light Color
The studies have proven it: rectangular rapid flashing beacons (RRFBs) work. Yield rates can be as high as 96% where RRFBs are installed. That’s a huge increase when yield rates are as low as 18% with a simple painted crosswalk.
LEARN WHAT’S NEW IN IA-21 VS. IA-11 On March 20, 2018, the Federal Highway Administration issued Interim Approval 21 – Rectangular Rapid-Flashing Beacons at Crosswalks in the Manual on Uniform Traffic Control Devices (MUTCD).
Carmanah Propels RRFB Technology Into the Open Market
Following the Federal Highway Administration's termination of the rectangular rapid flashing beacon's (RRFB) interim approval in December 2017, Carmanah stepped up to help solve the issue. The IMSA covers this story in the following article released in April 2018.
ITE, FHWA and Carmanah Work Together to Reinstate RRFBs
After the Federal Highway Administration announced the removal of the rectangular rapid flashing beacons (RRFBs) from the MUTCD Interim approval in December 2017, several key players in the traffic and transportation industry stepped up to save this important pedestrian safety device.
Mr. Richard D. “Rick” Jones decided to sell his patents to Carmanah Technologies Corp. so that Carmanah could disclaim these patents. By disclaiming the patents, Mr. Jones’ lifesaving RRFB technology was placed in the public domain.
Improving Walkability within Existing Urban Design
The convergence of road infrastructure being over capacity and changing demographics is creating a shift in urban planning focus towards principles of multi-modal transportation, increased pedestrian service levels, and compact development.
How Site Shading Influences Solar-Powered Beacon Viability
Shading is one of the most important aspects to consider when choosing a solar-powered beacon. However, it is often overlooked in the design of projects and its omission can lead to unreliable system performance.
How the Array-to-Load Ratio Helps Specify Solar-Powered Beacons
When specifying solar-powered beacons for a project, it is important to know what energy-in and energy-out elements to consider for energy balancing. The next step is to compare the two and determine the array-to-load ratio (ALR), which will reveal the most effective energy balance for your project.
The Role of Energy Balance in Specifying Solar-Powered Beacons
Not all beacons are created equal. To ensure solar-powered beacons maintain a reliable operating capacity and provide sustainable performance, it’s important to first understand the elements involved in both energy in and energy out.
