The article explores the congestion level in traffic of motor vehicles and its negative environmental and economic consequences in case of Kiev. The amount of pollution from traffic jams in Kiev and the number of vehicles which got into them in 2009-2018 is analyzed. The loss of earnings on the side of automobile owners from their standby are calculated with corresponding quantitative expressions found and described. For the course of the research, the methods of system-structural and comparative analysis were used for analyzing the environmental and economic problems of modern automobile systems; methods of formal logical analysis were used for substantiating the innovative infrastructure of transport routes. Separately economic and statistical methods were used in the study for trends development, structure analysis, and estimation of the influence of road congestion on the environmental and economic sphere. Pearson test has indicated a close relationship between the number of cars in Kiev and the number of values from traffic jams in environmental and economic sphere. Solutions to this problem are offered in forms of automated traffic control systems, improvisation of organizational and technical methods for the distribution of traffic flows over time, namely reverse traffic, road junctions, smart traffic lights, road extension, and the transition to alternative modes of transport. In all countries of the world there are new research methods that affect pollutants from motor vehicles. It is proved that they are forced by the recipients. In addition, landscaping can improve landscape design, reduce greenhouse gas emissions, surface water runoff and noise pollution. In this regard the policy implication of the research are aimed to eliminate the negative consequences from the use of vehicles during traffic jams, and the necessary number of trees for planting in Kiev is calculated. Key words: motor transport, congestion, traffic jam, motor vehicle, greening, compensation effect, lost profits, losses.

Methanol Fuel Cell

This paper presents thermodynamic analyses of ten different scenarios for using natural gas to power motor vehicles. Specifically, it presents a comparison between different types of automotive vehicles using fuels made from natural gas feedstock. In comparing the various fuel-vehicle options, a complete well-to-wheel fuel cycle is considered. This approach starts with the well at which the feedstock is first extracted from the ground and ends with the power finally delivered to the wheels of the vehicle. This all-inclusive comparison is essential in order to accurately and fairly compare the transportation options. This study indicates that at the present time hybrid-electric vehicles, particularly those using diesel components, can achieve the highest efficiency among available technologies using natural gas as the primary energy source. Hydrogen spark ignition, all-electric battery-powered, and methanol fuel cell vehicles rank lowest in well-to-wheel efficiency because of their poor fuel production efficiencies.

Warning Time

There are many issues related to highway–railroad grade crossings. For historic and practical reasons, trains have the right-of-way at grade crossings, which results in delays to motorists. In addition, the differential in size, speed, and stopping ability between motor vehicles and trains raises many serious safety concerns. Historically, the methods used to address these delay and safety problems at grade crossings have been reactive in nature. For example, the Manual on Uniform Traffic Control Devices specifies a minimum of 20 s of warning time for active warning devices at grade crossings. Intelligent transportation system (ITS) technology offers potential solutions for increasing the warning time at grade crossings. Advanced on-board devices and off-track detection equipment can allow train position and speed to be monitored. This information can be shared through wireless and wireline telecommunications equipment being deployed for ITS. Transportation management center personnel can then predict the arrival and crossing times of trains at grade crossings. It is hypothesized that if the warning time could reliably be increased, the traffic-operation strategies in the vicinity of grade crossings could be more proactive, reducing delay to motorists and increasing safety for both trains and automobiles. The research focuses on a second-generation technology approach to an advanced prediction of train arrival and crossing (gate-up and gate-down) times at highway–railroad grade crossings, including problems faced at grade crossings, background on detection and prediction technology for grade crossings, the train monitoring system used as the test bed for the research, the development of the methodology, the results of the analysis, and the conclusions of the research and potential applications for the model.

Mode Of Transportation

A key attribute of light rail transit (LRT) is its ability to integrate well into urban environments, sharing the public right-of-way with motor vehicles, bicycles, and pedestrians. This characteristic has made LRT very successful in urban corridors that require a high-capacity mode of transportation operating in a shared (on-street or mall) right-of-way environment. Although LRT is an inherently safe mode of transportation, accidents do occur. Such accidents negatively affect not only the parties involved, but also the operation of the entire LRT system and the reputation of the transit property. LRT accident data indicate that the most prevalent type of light rail vehicle (LRV)-motor vehicle accident occurs when motor vehicles turn left or right across LRT tracks and collide with an LRV rapidly approaching the intersection. Five of the most-common types of such accidents are identified, and traffic control devices and techniques are recommended to improve safety by conveying to the motorist the higher level of risk in violating a left or right turn signal prohibition.

Object Of Study

The article deals with the peculiarities of domestic and foreign experience hubs. The object of study - the process of multimodal transport hubs in traffic. The purpose of the work - in analyzing the domestic and foreign experience of transport nodes to identify ways to improve multimodal transport nodes. The research method is analytical. The most important structural unit of multimodal transport systems are multimodal transport nodes. By the term multimodal transport hub (MTH) understand the geographical point of docking and interaction of several types of transport, through which multimodal transportation is carried out. Such a hub may combine the railway stations connecting their railways, sea and river ports, airports, stations, highways, terminal and intermediate objects of main pipelines, and municipal transport networks. The infrastructure of the MTH includes warehouses and cargo terminals with traffic control and distribution centers, customs clearance facilities, transport insurance, organizations representing freight forwarding and banking services. In the analysis of domestic and foreign experience of transport hub, it was discovered that transport nodes are the bridgeheads of organizational-technical and technological interaction of different types of transport, implementation of multimodal transportations on logistic principles. The capacity of transport hubs in Ukraine is at a critical point. In modern conditions, the power of transport hubs is not sufficient for the volume of freight traffic, including and transit grew. In order to eliminate "bottlenecks" in transport hubs of Ukraine, it is necessary to improve the technical and operational capabilities of the infrastructure objects, their technical re-equipment and modernization. The results of the work can be applied to develop measures for the improvement of multimodal transport hubs. Foreseeable assumptions about the development of the research object - the search for ways to improve multimodal transport hubs. KEY WORDS: MULTIMODAL TRANSPORTATION, MULTIMODAL TRANSPORT HUBS, WAYS OF CONNECTION.

Cardiovascular Biomarkers

Abstract One central topic in ergonomics and human-factors research is the assessment of mental workload. Heart rate and heart rate variability are common for registering mental workload. However, a major problem of workload assessment is the dissociation among different workload measures. One potential reason could be the disregard of their inherent timescales and the interrelation between participants’ individual differences and timescales. The aim of our study was to determine if different cardiovascular biomarkers exhibit different timescales. We focused on air traffic controller and investigated biomarkers’ ability to distinguish between conditions with different load levels connected to prior work experience and different time slots. During an interactive real-time simulation, we varied the load situations with two independent variables: the traffic volume and the occurrence of a priority-flight request. Dependent variables for registering mental workload were the heart rate and heart rate variability from two time slots. Our results show that all cardiovascular biomarkers were sensitive to workload differences with different inherent timescales. The heart rate responded sooner than the heart rate variability features from the frequency domain and it was most indicative during the time slot immediately after the priority-flight request. The heart rate variability parameters from the frequency domain responded with latency and were most indicative during the subsequent time slot. Furthermore, by consideration of biomarkers’ inherent timescales, we were able to assess a significant effect of work experience on heart rate and mid/high frequency-band ratio of the heart rate variability. Results indicated that different cardiovascular biomarkers reveal different inherent timescales.
