Abstract:
To verify the number of forecasted passengers which will cause accessing to the Second Bangkok International Airport by road transport to be critical, thus another mode of transportation must be found to ease the situation. In the course of the study, parameters examined include forcast yearly peak hour traffic volume on the planned and existing road network in and around the airport, curb frontage requirement and circulation system in front of the passenger terminal. Once the critical number of passengers was ascertained, other choices of transport mode were looked at and rail mode was chosen. Three types of train namely High Speed Train (HST), Evaluated Bangkok Transit System (BTS) and State Railway of Thailand (SRT) were studied for their suitabilities. State Railways of Thailand (SRT) was found to be the most appropriate in terms of availability, practicality and cost effectiveness. The most suitable location for downtown station is at Makkasan area when compared to Hua Lampong and an area belongs to the Tobacco Factory in terms of land availability, accessibility by road and rail, ease in implementation, attainable in required frequency of services and least road-rail interfaces. Type of train will be the existing diesel rail car upgraded to suit air traveler's needs with services start at 05.30 to 23.30 hrs. with the frepuency of 15-20 minute interval.
