Airfield Design for Large Unmanned Aircraft Systems—A Guide

Developments in unmanned aircraft systems (UAS) technology and the seemingly endless applications of this technology offer society a broad spectrum of enhancements and solutions to many problems. The TRB Airport Cooperative Research Program's ACRP Research Report 238: Airfield Design for Large Unmanned Aircraft Systems—A Guide provides a fundamental understanding of large UAS (L-UAS) and their typical supporting infrastructure needs, which will assist airport sponsors with determining potential enha [...]

Development of a Small Aircraft Runway Length Analysis Tool

An important operational characteristic of an airport is the length of its longest runway. The longest runway determines the types of aircraft that can use the airport and dictates the operational limitations at the airport. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 54: Development of a Small Aircraft Runway Length Analysis Tool provides a user-friendly computer tool to help airport planners and designers estimate runway length requirements for a variety of aircraft and design [...]

Dynamic Curbside Management: Keeping Pace with New and Emerging Mobility and Technology in the Public Right-of-Way, Part 1: Dynamic Curbside Management Guide and Part 2: Conduct of Research Report

Dynamic curbside management has been the purview of cities, with much of the relevant research and guidance directed toward local transportation agencies. However, state departments of transportation, metropolitan planning organizations, and other regional agencies can be important partners for these local entities because, in many cases, roadways and other curb zone elements are part of the regional or state network. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 340: Dy [...]

A Retroreflective Road Lane Marking Tape 1,000X Brighter than Existing Technology

Approximately 1,282 fatalities on U.S. interstate highways in 2020 were due to nighttime road departures. A new ultra-bright retroreflective lane marking tape can save lives as well as offer both a very short payback period and a very substantial benefit/cost ratio over its useful lifetime. The TRB IDEA (Innovations Deserving Exploratory Analysis) Program's NCHRP IDEA Final Report for Project 228: A Retroreflective Road Lane Marking Tape 1,000X Brighter than Existing Technology details a new product whic [...]

SDR traffic – The high-performance traffic data classifier for two lane/direction roads.

Which kind of traffic data do you need today? Which kind you might need in 5 years? The versatile traffic data collection device will collect today and tomorrow´s traffic data and the flash updatable firmware will ensure future compatibility!

You will get answers to the following questions:

What is the current vehicle speed level per traffic direction?
How many vehicles are traveling per traffic lane?
What is the current percentage of truck traffic?
How many bicycles are riding on our bike lanes?

The SDR is a versatile and reliable traffic classifier using an inbuilt microwave (radar) sensor to measure traffic at a one or two lane (opposite direction) road layout.

The easy setup of the self-calibrating SDR and online traffic monitoring can be done on site by the use of a smartphone without interrupting the traffic flow.
Modern on-board GPRS wireless communication enables the user to access the data remotely without being on site.

The low power design of the SDR in combination with the solar power option extends the SDR data collection capabilities to 365 days per year.


Binning of traffic in two classes car/truck	Binning of traffic in 4+ classes, overhead installation available

Easy an enduring: Your system can be updated at any time and GPRS will keep your systems always up-to-date. Install the newest firmware or book new functions, all from your workplace

Total control at any time with myTrafficData! We-based access to you database wherever you are. You can access your data, visualize statistics and generate reports. Administration of several products is comfortable and safe.
