As a reliever airport for the Phoenix Sky Harbor International Airport, Phoenix–Mesa Gateway Airport must keep track of information for nearly 300,000 aircraft operations and 1.4 million passengers a year. To meet this challenge, the airport developed an innovative, digitally connected solution with the help of ACRP Research Report 182: Guidancefor Planning, Design, and Operationsof Airport Com...

Accurate traffic forecasts for highway planning and design help ensure that public dollars are spent wisely. Forecasts inform discussions about whether, when, how, and where to invest public resources to manage traffic flow, widen and remodel existing facilities, and where to locate, align, and how to size new ones. The TRB National Cooperative Highway Research Program's NCHRP Report 934: Traff...

Incompatible land uses can threaten the safe utility of airports and expose people living and working nearby to potentially unacceptable levels of noise or safety risk. At the state level, all 50 states have enacted some form of airport zoning legislation since the 1950s. The majority of states (90 percent) have enacted laws mandating or enabling local governments to adopt, administer, and enfo...

A database of active work zones is established in Work Zone Mapping and Tag Deployment System , a report from the Center for Transportation Studies at the University of Minnesota. This report is the third in a series of reports that exist to improve driver safety in work zones. The database described in this report provides an online, real-time portal for storing, monitoring, and inspecting wor...

This report focuses on how speed along corridors may be maximized to accommodate bicycles. The report is available for no fee after logging onto the site.

Measures that are effective at reducing speed, such as speed humps and mini traffic circles, are sometimes used in low-speed areas such as school zones. But they are often not recommended or allowed (via local policy) on the higher-speed streets typically associated with the highest injury severity for pedestrians. For those higher-speed streets, redesigning them to communicate lower speed, suc...

A congestion charging policy for two Australian cities is detailed in Right Time, Right Place, Right Price: A Practical Plan for Congestion Charging in Sydney and Melbourn e, a report from the Grattan Institute in Australia. This report also addresses how to deal with privacy concerns that may arise as a result of congestion pricing.

The relationships between winter weather, safety, and winter maintenance operations are determined in Relationships Between Weather and Roadway Safety , a report from the Institute for Transportation at Iowa State University. The goal of this report is to develop crash frequency and severity models that consider weather-related factors.
