Authorities in Slovenia and other EU member states are confronted with problems of city transportation. Fossil-fuel based transport poses two chief problems – local and global pollution, and dwindling supplies and ever increasing costs. An elegant solution is to gradually replace the present automobile fleet with low emission vehicles. This article first explores the economics and practical viability of the provision of solar electricity for the charging of electric vehicles by installation of

The impact of the economic crisis, i.e. the decrease in purchasing power in the Republic of Croatia, has been reflected negatively on the sales of new road vehicles and the maintenance plan of used road vehicles. A comparison of the results of technical inspections on vehicle roadworthiness has indicated a slight increase in unroadworthy vehicles, with a tendency for this to increase. Unroadworthiness and the average age of vehicles amounting to 12.18 years prompt for thinking about road safety

One of the main issues found in the UK is that when one HGV is trying to overtake another on a motorway (freeway), the 56mph speed limit imposed means that the time to complete this task is substantial. This forces other road users to use the overtaking lane and causes a bottleneck, increasing road rage and the risk of accidents.

Despite the rapid and continuous progress in the construction of vehicles and accompanying improving road infrastructure, the road safety issue remains very serious. Especially, it concerns intersections and road junctions where nearly 30% of road accidents take place. The paper is focused on a new intelligent path displaying support system to be installed on intersections of complex geometry combined with multiphase traffic lights. It consists of optical projection of two different horizontal

The intersection of a public road with a railway line in one level, called a rail-road crossing, is a particularly dangerous place due to the traffic flows crossing it. The regulations give absolute priority to a rail vehicle over a public road user; in addition, significant differences in the masses and speeds of moving vehicles require traffic regulation consisting of adequate passage protection. To this end, the road on which motor vehicles is equipped with road signs informing drivers that

One of the quality indicators of the transport service in passenger transport is the regularity of the movement of vehicles. Apart from the planned traffic intervals, it depends on a number of factors related to the traffic conditions of the public transport in the locality (intensity and composition of the traffic flow, passenger traffic structure, traffic lights regime, atmospheric conditions, etc.). The paper assesses the regularity of mass urban passenger transport traffic in the conditions

The study aimed to estimate the forces which are affecting the suspension of the vehicle during the contact between a tyre and roadblock. Using the video recording it is possible to calculate the values of the tyre deflection and forces acting in the system. The obtained deflections of the tyres were compared to earlier laboratory test results

Unfortunately, it is harmful no only to humans but also more to aquatic life. For this reason, there is an attempt to minimize its use. This paper presents the results of testing four groups of samples with different Cu contents (5, 10, 15, and 20%). Laboratory tests were performed using calorimetry, hot wire method
