With specific headway instructions drivers are not able to attain the exact headways as instructed. In this study, the effects of discrete headway feedback (and the direction of headway adjustment) on headway accuracy for drivers carrying out time headway instructions were assessed experimentally.

Transportation Research Record: Journal of the Transportation Research Board, 2016
This report analyzes the impact of smart card fare payments on transit bus dwell time. Shorter dwell times improve travel speeds and reduce headways, which encourage patronage. First, determinants of dwell time are discussed through a review of existing literature.

A recently completed $120-million headworks is helping Columbus, Ohio, make significant progress in reducing sewer overflows. The innovative facility includes what are believed to be the largest self-cleaning trench-type wet wells in the United States, selected because they reduce space requirements and costs, minimize odors and corrosion potential ...

Peach is the third most produced crop among temperate climate fruitspecies after apple and pear. Peach trees shed their leaves during winterdormant period. Peach that grows in the form of tree is a perennialwoody plant. Peach trees can live up to 20-30 years.

Transportation Research, 1975
Four headway models of increasing generality are considered from three points of view. We discuss (i) the value of the models for use as arrival processes in stochastic model building, (ii) some traffic situations where it is known from theoretical considerations, that the models are appropriate, and (iii) empirical evidence to support the models.

Learning Headway Estimation in Driving
Human Factors: The Journal of the Human Factors and Ergonomics Society, 2007Objective: The main purpose of the present study was to examine to what extent the ability to attain a required headway of 1 or 2 s can be improved through practical driving instruction under real traffic conditions and whether the learning is sustained after a period during which there has been no controlled training.

The time headway process has great practical as well as theoretical significance in highway engineering. The chapter deals with the basics which statistically characterize a process of time intervals between vehicles of a traffic stream.

Embargo Impedes Scientific Headway
Science, 1998A tightening of the U.S. embargo in 1992 and restrictions on travel between the countries have hindered science, forcing Cuban scientists to buy most of their supplies from Europe and thereby adding delays and increasing costs, especially for items that are made only in the United States.
