This research analyses the characteristics of travel time reliability for the road network in Kota Bandar Lampung. The research was carried out by evaluating five main roads in this city, namely Z.A. Pagar Alam, Teuku Umar, Radin Inten, Ahmad Yani and R.A. Kartini. Therefore, travel time consists of access, wait and interchange time, while its reliability deals with variations of in-passenger/private cars time, excluding commercial vehicles such as trucks, buses, trailers and motorcycles. However, wait times, was mainly related to the unreliability of the service, such as u-turn facility and roadside activities consisting of school/universities area, market, and hospital, which in turn reflected variations of in-vehicle times. Survey of travel time on each road was carried out for 12 hours (from 06.00 to 18.00) for five working days, including free-flow travel time (FFTT), while the fluctuation of speed on a road segment was reviewed and directly obtained using an application program. 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. Except for Radin Inten Road, four other roads indicated that the travel times occurred during AM peak (06.00 to 08.00) and PM peak (16.00 to 18.00) was longer than the midday (08.00 to 16.00). The travel speed fluctuation on road network showed that a low traffic speed on several segments of the road was mostly caused by minor drivers seeking to enter the main road's traffic, pedestrian trying to cross the road and roadside activities. Furthermore, based on the characteristics of travel time reliability, Z.A. Pagar Alam and Teuku Umar Road had index values higher than others, which represented the worst level of congestion.
