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 [...]

The HI-TRAC CMU is a small, low powered, low cost electronic system capable of monitoring up to 4 cycle lanes and 4 pedestrian lanes.

The CMU uses established pyroelectric infra red sensors to detect pedestrians.

The CMU can be powered by a small 3W solar panel mounted on top of a small pillar, supported by two rechargeable 6v 8AH batteries to form a fully standalone permanent solution.

The CMU unit is sealed to IP68 and can be installed into a small pillar or post.

The CMU can be configured to automatically transmit traffic data via GPRS/2G/3G/4G to a web server for secure data storage to a database.

Legacy GSM dial-up communication is also supported.
