Abstract Bus Rapid Transit (BRT) systems have become a popular type of transportation in recent years thanks to travel comfort they present, travel time advantages and low investment costs compared with those of railway systems. BRT systems are used effectively in many parts of the world and showing a continuous increase in travel demand. BRT system in Turkey is currently applied only in Istanbul. This study focuses on the comparison of Istanbul BRT with some other BRT systems in developing countries. The BRT systems analysed through Data Envelopment Analysis (DEA) are those which have been evaluated and scored in terms of various criteria by ITDP. In other words, the BRT systems included in this study are those having BRT scores. Since most of the BRT systems are used in overcrowded cities, the inputs and outputs used in efficiency analysis have been specifically chosen from these cities. As a result of the findings, the study offers some improvement recommendations for the current BRT system in Istanbul and other BRTs in overcrowded cities. Besides being one of the three important outputs, BRT standard score is also a physical performance indicator and, therefore, this study provides a fairer and analytic comparison of different BRTs of developing countries.

Introduction Public transportation systems are one of the most important factors that affect the development of and mobility within cities. The increasing number of vehicles and also the need for mobility along with the fact that these needs are met through buses cause an increase in the traffic. At the same time, due to the busy traffic delays and long waits at roundabouts, conventional bus services are negatively affected and thus, bus transportation is seen as an uncomfortable service with low quality. Limited railway systems fall short of meeting the mobility need of the population. In addition, the increase in the amount of traffic congestion and the duration of trips have made authorities come up with different solutions than traditional bus systems.

BRT systems have come out as an alternative and sensible solution when the criteria of time, cost, capacity and speed are taken into consideration. BRT system could be defined as a light rail system with a rubber-tyre vehicle providing flexibility and lower cost. In other words, BRT is a kind of high quality, fast, comfortable, cost-effective and useroriented transportation system providing effective urban mobility [24]. The successful application of BRT in Bogo
