Solar energised transport solution and customer preferences and opinions about alternative fuel Vehicles – the case of slovenia

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

Learning to scan for approaching vehicles efficiently with a visual impairment

street safely, pedestrians must be able to reliable detect the vehicles approaching their intended path. The human vision-cognition system, and the typical manner that people use it, can present problems for people with visual impairments when effective adaptive behaviors are not acquired and used. The field of Orientation & Mobility (O&M) has traditionally had a set of procedures for people with visual impairments to traverse streets. By default, most techniques incorporate tasks reliant upon

Impact of the economic crisis on the roadworthiness of vehicles in the Republic of Croatia

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

Proof-of-Concept Development for a Weight-toSpeed System on Heavy Goods Vehicles

Heavy Good Vehicles (HGVs) can cause several problems for road user’s world-wide. 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.

ON BOARD EXHAUST EMISSION MONITORING OF ROAD VEHICLES - A HIGH TECH SOLUTION TO POLLUTION FROM TRAFFIC?

A significant proportion of the atmospheric pollution that exists particularly in urban areas arises from road vehicles and primarily cars. The European Commission (EC) have introduced a series of regulations, the so called EURO Emission directives from Euro I in 1991 to the present day Euro IV. This legislation and similar ones in other global regions have helped to greatly reduce emission levels from road transport. However, a massive increase in the number of cars on the road have meant that

Method for pre-processing of level crossing image

Actuality of problem in the improvement of transport safety at level crossings (LC) is caused by increasing the number of vehicles and reducing discipline of vehicle drivers. One of ways for solution of this problem is associated with using the video surveillance systems for monitoring danger area of level crossing. In such systems due to the limited bandwidth of data channel usually the image compression techniques are used. In this paper the pre-processing method for compression of images is
