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

Vehicle Index Estimation for Signalized Intersections Using Sample Travel Times
Procedia - Social and Behavioral Sciences, 2013 AbstractWe introduce in this paper the concept of vehicle indices in a cycle at a signalized intersection which are the positions of vehicles in the departure process of the cycle. We show that vehicle indices are closely relate to the vehicle arrival and the departure processes at the intersection.

Link-level travel time measures-based level of service thresholds by the posted speed limit
Transportation Research Interdisciplinary Perspectives, 2019 Macroscopic parameters, such as density, volume-to-capacity ratio, and speed, are traditionally used to assess the level of service (LOS) of freeway/expressway or arterial road links.

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

Bus Operation Monitoring Oriented Public Transit Travel Index System and Calculation Models
Advances in Mechanical Engineering, 2013 This study proposed a two-dimensional index system which is concerned essentially with urban travel based on travel modes and user satisfaction. First, the public transit was taken as an example to describe the index system establishing process.
