The Value of Passenger Car Equivalent using the Time Headway Method on Urban Roads

Civil Engineering Dimension
The escalating proliferation of vehicles has had a significant impact on the existing Passenger Car Equivalent (PCE) values, making them less effective under current traffic conditions for assessing road performance.

Queue clearance rate method for estimating passenger car equivalents at signalized intersections

Journal of Traffic and Transportation Engineering (English ed. Online), 2017
This study explored the use of queue clearance rate method for estimating passenger car equivalent (PCE) at signalized intersections. PCE was estimated based on the assumption that the rate at which a queue of vehicles clears the intersection is a ...

Looking for Trouble: Pre‐Intervention Monitoring in Human and AI Driver Training

Symbolic Interaction, EarlyView.
We compare two types of situations involving monitoring of car driving: a driving instructor overseeing a trainee driver and a safety driver overseeing the performance of autonomous vehicle (AV) software. Our focus is on instances of monitoring that precede (1) interventions that are aborted before impacting the driving and (2) actual interventions on ...

Do the public take action when a severe snow warning is issued?

Weather, EarlyView.
Extreme weather events pose significant risks to the population, making timely warnings essential for preparedness. The UK Met Office’s National Severe Weather Warning Service (NSWWS) has issued impact‐based alerts for over a decade, yet evaluations of their effectiveness remain limited.

Passenger car equivalents for urban roads using average time headway of car following conditions [PDF]

Advances in Mechanical Engineering, 2019
Passenger car equivalents are used to calculate capacity and evaluate service level of urban roads. This article uses the average time headway of different car following conditions to replace the total average time headway of road vehicles, and the proportion of large vehicles to improve the headway method.

The Problem With Efficiency as a Pervasive Principle in Business School Academia, and What a Sufficiency‐Based Approach Can Do Better

British Journal of Management, EarlyView.
Abstract Efficiency is a pervasive yet insufficiently challenged managerial principle and an integral part of business school academia. However, while there is compelling evidence that efficiency gains can have severe undesirable social and ecological consequences that reduce overall welfare both in terms of well‐being and natural resources, business ...

Two-Lane Highway Capacity Estimation Based on Geometric Features

Civil and Environmental Engineering, 2023
The majority of roads in most countries are two-lane highways. These lanes quickly reach their capacity and must be upgraded on a regular basis. To do so, we must first determine the capacity of the street.
