Method of estimating street-road network level of service based on time and buffer indices

open access: yesИнтеллект. Инновации. Инвестиции, 2019
Due to the growing level of motorization while maintaining the capacity of existing roads, as well as due to the need to design and build new ones, the question of assessing the quality and reliability of traffic management is becoming increasingly ...

Exploring the Connection between Helioseismic Travel Time Anomalies and the Emergence of Large Active Regions during Solar Cycle 24

open access: yesThe Astrophysical Journal, 2023
We investigate deviations in the mean phase travel time of acoustic waves preceding the emergence of 46 large active regions observed by the Helioseismic and Magnetic Imager.

Time travel on the instalment plan: The index and future form in building [PDF]

open access: yesPhilosophy of Photography, 2012
The contemporary architectural rendering, digitally engineered and published in advance of construction, has come to resemble an image of an existing building so closely that it is hard to tell future from past. In constructing an appearance of an existing lived reality, which previously arose from the camera’s re-presentation of the trace of past ...

TRAFFIC CONGESTION LEVEL IN 10 SELECTED CITIES OF POLAND [PDF]

open access: yesScientific Journal of Silesian University of Technology. Series Transport, 2021
Transport has a great impact on human activities but contributes to many negative phenomena occurring in road traffic, for example, road traffic accidents, emission of toxic exhaust fumes into the atmosphere and a high share of cars in road traffic.

A new phase space method for recovering index of refraction from travel times [PDF]

open access: yesInverse Problems, 2007
Summary: We develop a new phase space method for reconstructing the index of refraction of a medium from travel time measurements. The method is based on the so-called Stefanov-Uhlmann identity which links two Riemannian metrics with their travel time information. We design a numerical algorithm to solve the resulting inverse problem. The new algorithm

Evaluation Indexes and Correlation Analysis of Origination–Destination Travel Time of Nanjing Metro Based on Complex Network Method [PDF]

open access: yesSustainability, 2020
The information level of the urban public transport system is constantly improving, which promotes the use of smart cards by passengers. The OD (origination–destination) travel time of passengers reflects the temporal and spatial distribution of passenger flow.
