This System Design Document (SDD) describes the scope of the proposed New York City (NYC) Connected Vehicle Pilot Deployment (CVPD) system. It is a continuation of the systems engineering work based on the system architecture identified in the System Architecture Document (SAD). Its objective is to identify the subsystems and decompose them further

Successes in Stewardship is a Federal Highway Administration (FHWA) bimonthly newsletter highlighting current best practices in stewardship and environmental review from around the country.
This report assesses the effects of the Federal Highway Administration's (FHWA's) investment in the Innovative Intersection Design research program and related activities on the availability and quality of such research; awareness and adoption of innovative intersection designs in the United States; and impact of deployed innovative intersection de

Traffic engineers and researchers calibrate microsimulation models using macroscopic inputs—such as aggregated traffic throughput—instead of microscopic inputs, such as intervehicle spacing and acceleration. This has led to concerns that these models have been capturing the microscopic driver behaviors inaccurately, despite the macroscopic performa
...
Through this project, researchers evaluated the safety effects of guardrails, utility poles, and side slopes using safety data from Indiana and Pennsylvania. Safety evaluations in this project focused on total, fatal-and-injury, and roadway-departure crash risk. Crash modification factors (CMFs) and benefit–cost (B/C) ratios were developed for the

The Federal Highway Administration (FHWA) Development of Crash Modification Factors (DCMF) program was established in 2012 to address highway-safety research needs and evaluate new and innovative safety strategies (improvements) by developing reliable quantitative estimates of their effectiveness in reducing crashes. Forty-one State departments of

Cooperative driving automation (CDA) aims to improve the safety, traffic throughput, and energy efficiency of the transportation network by allowing vehicles and infrastructure to work together to coordinate movement. The objective of this project is to advance the CARMA ecosystem to enable further capabilities for CDA participants to interact with

The Federal Highway Administration established the Development of Crash Modification Factors (DCMF) program in 2012 to address highway safety research needs for evaluating new and innovative safety strategies (i.e., improvements) by developing reliable quantitative estimates of their effectiveness in reducing crashes. The Evaluation of Low-Cost Saf

The objective of this Federal Highway Administration (FHWA) project was to determine the safety effectiveness of low- to medium-cost engineering countermeasures in reducing non-motorist (i.e., pedestrian) fatalities and injuries at controlled and uncontrolled intersections. The project started with a survey to identify the use of pedestrian treatme

Life Cycle Planning (LCP) is “a process to estimate the cost of managing an asset class, or asset sub-group, over its whole life with consideration for minimizing cost while preserving or improving the condition (23 CFR Part 515).” Since LCP is a relatively new process for State DOTs, the Federal Highway Administration (FHWA) developed a handbook o

Traffic Volume Trends is a monthly report based on hourly traffic count data reported by the States. These data are collected at approximately 5,000 continuous traffic counting locations nationwide and are used to estimate the percent change in traffic for the current month compared with the same month in the previous year. Estimates are re-adjuste
