TL;DR: A methodology for analysis of road networks based on energy consumed by the vehicles and the energy needed to build more efficient connections is proposed, which takes into consideration traffic volume, shares of vehicle classes, road geometry and energy needed for road operation and construction.

TL;DR: In this article, a probe center side is formed to acquire the travel path of the vehicle via mobile phone communication network through a mobile phone, and determine roads corresponding to the vehicle specified by the GPS to be in the situation of traffic jam or congestion.
Abstract: In a traffic situation determination system, a vehicle side is formed to transmit information relating to the travel path of the vehicle specified by the GPS to the probe center when traveling on roads calculated to have the degree of traffic jam or congestion, while a probe center side is formed to acquire the travel path of the vehicle via a mobile phone communication network through a mobile phone, determine roads corresponding to the travel path of the vehicle specified by the GPS to be in the situation of traffic jam, and determine roads corresponding to the travel path of the vehicle specified in the mobile phone communication network to be in the situation of no traffic jams

TL;DR: In this article, it is suggested that if the three flow zones concept is accepted, there is a possibility of ultimately arriving at satisfactory theoretical solutions based on an extension of queueing theory in the zone of normal flow, and based on car following theory in a zone of forced flow, the unstable flow being incapable of theoretical analysis.
Abstract: In this paper various traffic flow models are discussed. It is suggested that, if the three flow zones concept is accepted, there is a possibility of ultimately arriving at satisfactory theoretical solutions based on an extension of queueing theory in the zone of normal flow, and based on car following theory in the zone of forced flow, the zone of unstable flow being incapable of theoretical analysis. Some results of limited traffic bunching studies are also discussed (a).

TL;DR: The theory discussed in the present study enables us to predict the time-average sound level, LAT, when the distance between the stopping line and the receiver exceeds the road width, acceleration length, and the length of the vehicle’s queue.

TL;DR: This paper presents the first phase of an experimental implementation of vehicle longitudinal control at low speed, based on second order sliding mode technique, for increase of traffic capacity while improving safety and comfort.
Abstract: This paper presents the first phase of an experimental implementation of vehicle longitudinal control at low speed. The main objectives are the increase of traffic capacity while improving safety and comfort. Longitudinal control method used is based on second order sliding mode technique. Results are presented either by simulation or by use of an experimental process with a vehicle prototype which is equipped with needed sensors and actuators. The principle is based on the well management of inter-vehicular spacing in relation to vehicle speed. Examples obtained with the automatic system are provided for several traffic situations such as stop-and-go, stop on obstacles, car-following with merging/overtaking. Positive impacts of such a system are given in terms of traffic capacity enhancement and collision gravity reduction.
