    RISKS AND SAFETY ISSUES RELATED TO USE OF ELECTRIC AND HYBRID VEHICLES

    Trans Motauto World, Vol. 2 (2017), Issue 1, pg(s) 37-40

    Nowadays hybrid vehicles take increasing share of new road vehicles, but also the electric vehicles have continuous development which is a sign of a serious beginning of new era of their use. The goals of introducing of these vehicles include lowering of the negative impact on the environment and also reducing of their operational costs. Together with the mentioned trends, there are some specifics related to the risks of using this type of vehicles. This paper gives the key elements related to the development of hybrid and electric vehicles with emphasis of the general distinctions in terms of conventional vehicles with internal combustion engines. The paper has focus on risk identification and hazards that can arise from hybrid and electric vehicles, which are specifically related to their technical differences from conventional vehicles with internal combustion engine. Those risks exist when the vehicles are in use, but also even when the vehicle is not in operation. There is also identification of potential risks for the emergency staff when there is accident with these types of vehicles. The paper also addresses the possible harmful events that can happen later or because of improper repairs of the vehicles. Having in mind that the literature sources are quite moderate and in Republic of Macedonia there is none, the conclusion represent an effort to systemize the available knowledge in order to help vehicle users and professionals to mitigate or lower the recognized risks.

  • THE INTELLIGENT TRANSPORT SYSTEMS – RISKS AND BENEFITS

    Machines. Technologies. Materials., Vol. 8 (2014), Issue 3, pg(s) 25-27

    Effective deployment of ITS technologies depends in part on the knowledge of which technologies will most effectively address the issues of congestion and safety. Thus, it is important to understand the benefits or risks of both existing and emerging technologies. Based on documented experience locally and throughout the country, ITS deployments in urban areas have the potential to offer the following benefits:

    • Arterial management systems can potentially reduce delays with the implementation of advanced control systems and traveler information dissemination.

    • Freeway management systems can reduce the occurrence of crashes, increase capacity, and decrease overall travel times.

    • Freight management systems reduce costs to motor carriers with the implementation of the commercial vehicle information systems and networks.

    • Transit management systems may reduce travel times and increased reliability with automatic vehicle location and transit signal priority implementation.

    • Incident management systems potentially reduce incident duration and offer numerous other benefits.

    There is a wide range of benefits that can be obtained from ITS deployments. For example, fuel consumption, travel time, and delay can be reduced. ITS deployments can also result in higher travel speeds, improved traffic flow, and more satisfied travelers for all modes.
