      <title>Developing Capacity Estimation Metrics for Airports Accommodating Smaller Aircraft Using Locally Collected Automated Dependent Surveillance-Broadcast Data</title>
      <link>https://trid.trb.org/View/1971316</link>
      <description><![CDATA[Airport operators need good capacity estimates for many purposes, including to bolster applications for funding support for capacity improvements. Based on a recognized need to enhance models for estimating the operating capacity of airports serving a user base of smaller aircraft, such as small general aviation airports, this paper describes research conducted to leverage automated dependent surveillance-broadcast (ADS-B) data to develop aircraft performance characteristics for use as inputs to future small airport capacity models. The research addresses this challenge by constructing home-built ADS-B data collection units using a Raspberry Pi-based hardware platform and an Amazon Web Services-based cloud architecture housing the study’s PostGreSQL database, and python-based codebase. The work was focused at three participating airports: The Ohio State University Airport in Columbus, OH (KOSU); College Park, MD (KCGS); and Republic Airport in Farmingdale, NY (KFRG). The hardware units were deployed at three study airports, collecting more than 90?million individual ADS-B messages transmitted by aircraft operating within the vicinity of the study airport. Models were developed to clean, process, and assess the data, and leveraged to determine aircraft performance characteristics within these environments. Initial work focusing on assessing the fleet mix, approach speeds, aircraft separation in arrival streams, and runway occupancy times was performed. Findings from this research revealed a very high accuracy and richness of collected and processed data, and performance metrics that were reasonable, valid, and applicable for use as inputs to future airport capacity models.]]></description>

      <title>Neighborhood-Based Planning: Five Case Studies</title>
      <link>https://trid.trb.org/View/1120936</link>
      <description><![CDATA[Five recent neighborhood planning programs that have successfully involved residents to shape and implement neighborhood plans are examined in this report. Also described are specific ways that planning agencies can empower citizens with information and resources. The five case studies are in the following locations: Arlington County, Virginia; Kansas City, Missouri; Raleigh, North Carolina; Seattle, Washington; and College Park, Maryland. This report is not a "how to" on neighborhood planning, however; see the supplemental notes for additional resources.]]></description>

      <title>ASPHALT PAVEMENT TEMPERATURES</title>
      <link>https://trid.trb.org/View/100831</link>
      <description><![CDATA[THE USE OF THICKER ASPHALT PAVING COURSES IN HEAVY-DUTY HIGHWAYS HAS RESULTED IN THE NEED FOR MORE INFORMATION ON TEMPERATURE VARIATIONS IN PAVEMENT STRUCTURES. TEMPERATURE DATA ARE NECESSARY IN STUDIES OF PAVEMENT DEFLECTIONS, STRESSES AND STRAINS UNDER MOVING WHEEL LOADS. PAVEMENT TEMPERATURE DATA ARE OF INTEREST IN ANY STUDY OR TEST INVOLVING THE TEMPERATURE-DEPENDENT MECHANICAL PROPERTIES OF PAVING MIXTURES OR PAVING ASPHALTS. THE PAVEMENT TEMPERATURE STUDIES REPORTED WERE CONDUCTED TO PROVIDE INFORMATION ON TEMPERATURE VARIATIONS IN THICKER ASPHALT-CONCRETE PAVEMENTS THAT WOULD BE APPLICABLE IN MANY AREAS OF THE UNITED STATES. PAVEMENT TEMPERATURES WERE MEASURED AT THE SURFACE AND AT DEPTHS OF 2, 4, AND 6 IN. IN A 6-IN. THICK ASPHALT-CONCRETE PAVEMENT, AND AT DEPTHS OF 2, 4, 6, 8, 10 AND 12 IN. IN A 12-IN. THICK ASPHALT-CONCRETE PAVEMENT. A TEMPERATURE RECORDER WAS USED TO RECORD AIR AND PAVEMENT TEMPERATURES AT THE TEST SITE IN COLLEGE PARK, MARYLAND, FROM JUNE 1, 1964, TO MAY 31, 1965. THE DURATIONS OF VARIOUS TEMPERATURE LEVELS, AND MAXIMUM, MINIMUM AND AVERAGE TEMPERATURES BASED ON HOURLY TEMPERATURES AT THE VARIOUS DEPTHS, ARE REPORTED FOR EACH MONTH AND FOR THE ENTIRE YEAR. TEST DATA AND INFORMATION ON DAILY PAVEMENT TEMPERATURE CHANGES WITH DEPTH, AND RATES OF TEMPERATURE CHANGE, ARE ALSO REPORTED. /AUTHOR/]]></description>
