Joint design standard for running times, dwell times and headway times [PDF]
WIT Transactions on The Built Environment, Vol 88, 2006 A punctual train service requires a feasible timetable and this paper deals with design standards for running times, dwell times, and headway times. Feedback from operations to planning is an appropriate way to determine the required standards for delivering the desired performance.

Synergetic theory for jamming transition in traffic flow
, 2000 The theory of a jamming transition is proposed for the homogeneous car-following model within the framework of Lorenz scheme. We represent a jamming transition as a result of the spontaneous deviations of headway and velocity that is caused by the ...

Spacing Policies for Adaptive Cruise Control: A Survey
IEEE Access, 2020 Adaptive cruise control (ACC) systems are designed to provide longitudinal assistance for drivers to enhance safety and reduce workload. As the core of all ACC control algorithms, the spacing policy plays a crucial role in various aspects.

Physics of Autonomous Driving based on Three-Phase Traffic Theory
, 2017 We have revealed physical features of autonomous driving in the framework of the three-phase traffic theory for which there is no fixed time headway to the preceding vehicle.

TIME HEADWAY DISTRIBUTION OF TRAFFIC FLOW
Proceedings of the Japan Society of Civil Engineers, 1971 Arrival distribution of vehicles is one of the basic characteristics of traffic flow. Since average time headway is inversely proportional to the traffic volume it has been considered as an approach of the study of traffic capacity. Arrival distribution is essential to deal with the traffic flow stochastically in the problems such as queing problems of

Clinical Insights Into Hypercalcemia of Malignancy in Childhood
Pediatric Blood &Cancer, EarlyView.ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

Task-Difficulty Homeostasis in Car Following Models: Experimental Validation Using Self-Paced Visual Occlusion. [PDF]
PLoS ONE, 2017 Car following (CF) models used in traffic engineering are often criticized for not incorporating "human factors" well known to affect driving. Some recent work has addressed this by augmenting the CF models with the Task-Capability Interface (TCI) model,

Public transport values of time [PDF]
, 2001 OBJECTIVES The objectives of this aspect of the study are to provide recommended valuations of: • Public transport in-vehicle time (IVT) • Walk time • Wait time/headway with appropriate modifiers according to key factors such as: • Mode ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.
