Abstract

On the purpose of future transportation service requirement accomodation, traffic network and public transportation development are needed, it is needed to connect all transportation modes. With limited budget of Lampung Province, this kind of development needs reference, so it can have integrated planning. The purpose of this reasearch are to recognise the movement pattern and the effect of wisdom application that relates to transportation network on Lampung Province, and to recognise the effect of development planning on transportation network.. Domain of the research are province street and national street in Lampung Province, Data of Origin Destination Matrix on 2009, which used in this reasearch are secondary data that obtain from daily survey data with Furness Method to get the sum of movement on wisdom application planning. The result of the research are (1) Amount of movement patterns show a continous movement pat- tern of people from Palembang to Java Island and vice versa on 2014 is 8 million passengers for a year and from Bengkulu to Java Island and vice versa is 0,7 million passengers for a year, (2) All of scenarios increase street performance, especially after railway and Sumatera Toll development. After railway development, value of VCR changes from 0,83 to 0,45 on Simpang Asahan-Simpang Mesuji D. And the effect of Sumatera Toll development is value of VCR changes from 1,29 to 0,45 on Simpang Terbanggi Besar-Bandar Jaya, (3) Development of street network planning on traffic network and public transportation, railway, acrossing network, sea network, and air network on Lampung Province are needed.

Abstract

This research analyses the characteristics of travel time reliability for the road network in Kota Bandar Lampung. Therefore, travel time consists of access, wait and interchange time, while its reliability deals with variations of in-passenger/private cars time. Survey of travel time on each road was carried out for 12 hours (from 06.00 to 18.00) for five working days. Furthermore, the buffer time method was used to measure the characteristics of time travel reliability consisting of five measuring tools, namely planning time, planning time index, buffer time, buffer time index and travel time index. This research found that the temporal effects are the main factor that tends to affect travel time, whereas network effects are the second factor that tends to affect travel time. Furthermore, the regression equation was developed to express the effect of planning time (TPlan) and free-flow travel time on average travel time .
