Вплив змін динамічних характеристик транспортних засобів на значення коефіцієнтів зведення
(Видавництво Львівської політехніки, 2015) Гілевич, Володимир; Могила, Ігор
There is proposed the new approach for determination of the passenger car equivalent (PCE) for the heterogeneous traffic flows, which considers dynamic behavior of different vehicles. Reduction of the starting acceleration of vehicles that take off on the green light at the stop-line is considered when computing PCE for signalized intersection. There is shown reduction of traffic delays at the main directions of intersections when using proposed PCE.
Вплив технічного стану транспортних засобів на потік насичення
(Видавництво Львівської політехніки, 2018-02-22) Гілевич, Володимир; Національний університет «Львівська політехніка»
The analysis of methods of calculating the saturation flow has established that they do not take into account the technical condition of vehicles in transport flows. The expediency of taking into account the technical condition of vehicles in the calculation of the light cycle is shown.
Небезпеки автомобілізації
(Видавництво Львівської політехніки, 2023-11-09) Форнальчик, Євген; Гілевич, Володимир; Національний університет “Львівська політехніка”
It is known that the most important thing in maintaining the good health of citizens is to save their lives from possible fatal road accidents, ensure the cleanliness of the air space, isolation from excessive noise pollution, electromagnetic fields. The listed negative impacts generate intensive traffic flows, which are the main component of transport systems. The task of identifying the patterns of changes in motorization over the past five years has become important. Taking into account the extreme importance of ensuring the normal living space of the urban population, which is formed, including the norms of the functioning of the transport system. Motoriization, as it was previously believed, is one of the characteristics of the well-being of the population. Growth is already accompanied in large cities by negative phenomena, such as: road accidents with loss of life; deterioration of air pool quality; excessive traffic noise; excessive electromagnetic fields that cause intense traffic flows. All these negative characteristics of the increase in the level of motorization formed the subject of this study. First of all, the trends of changes in hazards by year were revealed based of statistical data: there is a constant increase for the period from 2017 to 2022.
Оцінка тривалості сполучення на автобусному маршруті
(ТзОВ «Галицька видавнича спілка», 2021-03-25) Форнальчик, Євген; Гілевич, Володимир; Національний університет “Львівська політехніка”
The duration of buses between the end points of the route was studied. Using the methods of statistical data processing, the numerical characteristics of the distributions of the duration of the connection by working days of the month were found. The expediency of continuing research in this direction is substantiated.
Про «затримки» автомобілів і транспортних потоків на вулично-дорожній мережі міста
(Посвіт, 2019-02-28) Форнальчик, Євген; Гілевич, Володимир; Національний університет «Львівська політехніка»
The so-called delays of individual cars and traffic flows in the streets and roads of the cities inflict, first of all, on losses for all participants of the movement. It is proposed to consider these delays not as delays in movement, but as obligatory time components of the technological process of movement between correspondence points.
