Consumer-Oriented Bus Information System

Case Study

Consumer-Oriented Bus Information System

The construction of the bus information system was initiated with the establishment of Seoul city’s intelligent transport system (ITS) in 2000. The contents of the public transportation sector from among a total of 5 ITS projects was to gather and analyze public transport information, allow bus operators to take advantage of the data for efficient transit operation and management to provide the users of public transit with the necessary information, and thus to enhance the transit service quality. Towards this end, the Bus Management System (BMS) for the operators and Bus Information System (BIS) for the users were pushed ahead separately: BMS was built up from 2003 to 2005 while BIS emerged as a fully-fledged system in 2009 after implementing its own pilot project from 2006 to 2008 .

●To improve bus punctuality.
● To upgrade operation order.
● To enhance bus competitiveness in ways to offer a variety of bus information and to draft reasonable public transport policies based on operation history.

Seoul city experienced a rapid growth of road construction and road facilities for the increased bus services, which in turn caused an increase in vehicles on the streets and road shortages. This industrialization resulted in the continuing income growth of Seoul citizens and a corresponding increase in car utilization – this led to a repetitive vicious cycle involving road congestion, the resulting reduction of bus speeds, and an increased road capacity which was intended as a solution, but failed to deal with the increased demand for roads.

The use of automobiles continued to grow despite the ongoing subway construction and expansion which continued since the beginning of the early 1970s; at the beginning of the 2000s, passenger cars came to account for 72% of Seoul traffic, and, more specifically,
drive-alone cars accounted for as much as 79%. This modal share rate signified an annual energy consumption amounting to 4.1 trillion won, and social costs due to traffic congestion amounted to approximately 5 trillion per year.

Results and Impacts

The most important policy effect is changes in public attitude and awareness on bus that new bus information has brought about. Three years after implementing the bus information system, the Seoul Transport Operation and Information Service(TOPIS) conducted an equivalent
quota sampling survey targeted at Seoul citizens aged 19 or over who use buses twice a week or more and confirmed the following contents

● Satisfaction index on using the bus information appeared to be overall high - 81.4% for bus stop guide terminals, 77% for mobile wireless Internet, 73% for website of Transport Operation and Information Service, and 72.8% for ARS services.

● 85% of the respondents cited bus arrival time as the most useful information.

● 91.9% of the experienced users answered that the bus arrival time information is "accurate."

● 67.2% of the respondents answered that an average waiting time was 10 minutes while 10.1% said it was longer than 10 minutes, which indicates that the perceived waiting time is relatively short. Based on this, it can be inferred that the reliable information about waiting times helped reinforce positivity of the surrounding environment and the waiting experiences while waiting. That is, the results suggest human psychology will make the uncertainty surrounding the waiting perceived as longer.

● 85.4% of the respondents answered that they are “satisfied” with bus information terminals (BIT), which is equivalent to 3.9 points out of 5. 96.5% of the respondents responded positively regarding the additional installation of the bus information
