Alternative and Transitional Energy Sources for Urban Transportation

In urban areas, the transportation sector is one of the principal sources of substantial energy consumption and carbon emission. Although diesel and gasoline are still the main energy sources used in urban transportation, alternative and transitional energy sources have been introduced. The alternative and transitional energy sources include electricity (used in hybrid, electric, and fuel-cell vehicles), biofuels, gaseous fuels from other sources (hydrogen, natural gas, and liquefied petroleum gas [LPG]), alcohols, and ethers. Alternative and transitional energy sources can be used to promote the development of sustainable transportation systems because these sources are renewable and have a lower environmental impact than diesel and gasoline. However, various technical, economic, and policy factors can prevent the successful application of alternative energy sources. In this review, we summarize the latest literature regarding alternative and transitional energy sources in order to understand the current applications of these energy sources in urban transportation and their future applications.

VEHICLE PARKING STANDARDS AS A SUPPORT TO SUSTAINABLE TRANSPORT SYSTEM: BELGRADE CASE STUDY / AUTOMOBILIŲ AIKŠTELIŲ STANDARTAI KAIP DARNIOS TRANSPORTO SISTEMOS PALAIKYMO PRIEMONĖ: BELGRADO ATVEJIS

Vehicle parking standards are related exclusively to parking in connection with: planning, construction, development and/or extension and change of use of the existing developments. On the other hand, vehicle parking standards are the key measure for managing the level of traffic and they should be an integral part of the urban transport policy. This would allow the parking standards to be applied also to the land use management in accordance with accessibility to the urban zones by means of travel other than by car. This implies that in the course of producing vehicle parking standards the level of parking restrictions is to be defined depending on the Public Transport Accessibility Level. If Public Transport Accessibility Level of a zone the subject development belongs to is high, the number of parking spaces to be provided is restricted and customers are encouraged to shift to alternative transport modes. Thus defined parking standards assist in the development of sustainable transport system. This paper will present the methodology for calculation of parking standards depending on the accessibility of the zone the subject development is located within. Santrauka Transporto priemonių stovėjimo vietų standartai numato naujų automobilių aikštelių planavimą ir statybą, esamų statinių išplėtimą ar pakeitimą. Kita vertus, automobilių aikštelių standartai yra pagrindinė priemonė, padedanti valdyti transporto srauto lygi. Jie tūretų būti neatsiejami nuo miesto transporto politikos. Tai leistų įvairias miesto zonas vykti ne automobiliais. Tai reiškia, kad automobilių aikštelių apribojimai turi būti suderinti su miesto viešojo transporto sistema. Jei viešojo transporto prieinamumo lygis konkrečioje miesto zonoje yra aukštas, automobiliu aikšteliu skaičius turi būti ribojamas, o miestiečiai turi būti skatinami naudotis alternatyviomis transporto rūšimis. Taip automobilių aikštelių standartai padeda pletoti darnia transporto sistema. Šiame straipsnyje pateikiama automobilių aikštelių skaičiavimo metodologija, įvertinanti atskirų miesto zonų pasiekiamumą.

Wedded to the car: women, employment and the importance of private transport

This paper draws on primary research undertaken in the North East of England (NE) to explore the importance of private transport in allowing women to access employment. It outlines the evidence base which exists to consider the impact of mobility on social exclusion. It then analyses the links between women, transport and the labour market, women's transport choices, and the relationship between women's access to private transport and their employment position. It concludes by arguing that access to private transport is a key factor in determining women's economic inclusion, and that the development of sustainable transport systems may have serious gender implications.
