Traffic congestion in major cities is a major problem which is growing steadily every year. It is clear that something must be done to curb this trend. Several different concepts are being investigated which can be used to minimize congestion and improve the traffic flow. Automation of the bus system represents one of those methods, and is the focus of this paper. Currently, public opinion of the quality of bus services is generally not perceived as adequate. Buses generally travel about 60% of the speed of other vehicles, and more often than not adherence to schedule is difficult to achieve. The consequence is that people choose to take personal transportation instead, causing increased congestion. Automation seeks to address this issue by offering decreased travel times, increased schedule adherence, and greater overall convenience compared to the current bus systems. The concept of automation is based on expanding upon the ideas of Bus Rapid Transit (BRT) and making the system as efficient as possible.

Mobility Solution

Bus rapid transit (BRT) is one of the strategies to promote improvements in urban mobility. In this study, BRT scenarios, which integrate exclusive bus lanes and bus priority signal control in mixed traffic scenarios, were modelled using a VISSIM microsimulation. Three scenarios of BRT were modelled to represent 16:84, 38:62 and 54:46 modal splits between public transport and private vehicles. It was found that Scenario 4 (the 54:46 scenario) offers better benefits in terms of delay time saving and economic benefits. In general, it was found that the BRT system enhances the functioning of the transport system and provides people with faster and better mobility facilities, resulting in attractive social and economic benefits, especially on a higher modal split of public transport. It is regarded as one strategy to alleviate traffic congestion and reduce dependency on private vehicles. The finding of this study provides an insight on the effective concept of the BRT system, which may promote the dissemination of an urban mobility solution in the city. The results can help policymakers and local authorities in the management of a transport network in order to ensure reliable and sustainable transport.

Different configurations of Bus Rapid Transit (BRT) system may cause different additional riderships. In this paper, in terms of network traffic equilibrium assignment principle, the additional riderships estimation model based on Variational Inequality (VI) model is presented. The bus frequency is related to variables including the travel time, the residence time in terminals, and the dwelling time at the stops. The additional riderships are translated into network additional traffic flow firstly. Given the bus frequency, VI model can be turned into Stochastic User Equilibrium (SUE) model to calculate the other variables. The similarity diagonalization method is used to calculate the elastic bus frequency and finally the network additional traffic flow can be computed. The additional riderships under different configurations of BRT system are compared in the numerical test. The results show that the additional riderships under different configurations have large differences and occupy a high percentage of the total ridership.

This paper seeks to understand participation in out-of-home activities by inhabitants in Dar es Salaam, and their perceptions toward informal public transport (IPT) and bus rapid transit (BRT) in supporting these activities. Without fixed schedules, IPT (e.g., minibuses, motorcycles, and tricycles) is used as a means of transport for different trips. However, IPT is burdened by poor roads, traffic congestion, and high transport demand. Many developing cities are seeking to replace IPT with formal BRT lines. However, little is known in relation to the ability of IPT and BRT to support out-of-home activity participation of the inhabitants. This paper reports on a study in Dar es Salaam exploring the relative contribution of each type of service. The study took place before the opening of BRT, and encompasses focus group discussions, participatory geographical information systems, and questionnaires carried out in two study zones: one close to a BRT corridor and the other in a peri-urban location. The findings show that IPT was used to support participation in daily activities like work, education, shopping, and social matters; and was perceived to be flexible in providing access to both high and low density unplanned settlements. The BRT was viewed to benefit specific groups of people, especially individuals working in permanent offices in and around the city center, particularly professional workers. This paper sheds light on how the two systems were perceived by the local people and can inform policy makers about possible improvements in public transport systems to support activity participation of their inhabitants.

ABSTRACTThe Government of Semarang have sought to develop a mass transportation system using theconcept of Bus Rapid Transit (BRT) in Mangkang‐Penggaron corridor. In order to effectivelyfacilitate the movement of city dwellers, the BRT system required the provision of functioningshelters along the corridor. There is a need to optimize the function of the shelters including theintegration to other modes of transportation and to the activities of the Central Business District(CBD), ensuring optimum performance of the whole BRT system. This study determined andevaluated the quality of BRT shelter services in Semarang based on user perception. The studyemployed analysis regarding the fulfillment of criteria for quality of services including waitingtime, convenience, service reliability, distance, and BRT shelter clerk services. The analysisprocesses concluded that the current BRT shelter services were in fact less than ideal. The studyfound lack of maintenance and the need for improvement of services at rush hour.Keywords: evaluation, quality of services, and bus shelter

Considering the increasing amount of traffic congestion and inconvenient travelling experiences a system needs to be designed to provide a hassle free travel which alleviates the travelling experience of the commuter and thrives them to choose this technology over any conventional implemented system or driving by own self. The system is designed to integrate a large number of areas together in order to create an efficient and economical system for the passengers to travel over long distances with comfort and safety. The Bus Rapid Transit System (BRTS) which is a public transport service is designed to mitigate the drawbacks of the previous systems as well as implement technologies in various domains including location tracking , communication services , monitoring and creating a detailed comparison with the conventional transportation services on multiple parameters in order to create a distinction and focus on the factors that make BRTS a much better mode of transportation as compared to the conventional transportation methods.

Preferences of heavy rail (HR) system users are studied in relation to the system’s alignment and bus connections in the context of a developing city. Stated preferences techniques are applied to estimate the monetary value of a long set of attributes of a new mass transit service: HR connected to bus rapid transit (BRT). Attributes include time, fare, bicycle storage at stations, stairways, feeder bus integration, integration with BRT, type of bus service, bus itinerary, and quality of buses. The long set of attributes deserved three stated preference experiments grouped by time and fare, characteristics of HR, and characteristics of BRT. They were linked by the common attribute of the fare. Results of the values of the attributes are presented. The value of the preference for HR is reduced to 8% when a feeder bus is not offered and the HR route does not reach downtown. The value of a feeder bus using small vehicles is higher than the value of BRT even if BRT operates with new buses and express service to downtown. Bicycle storage or escalators have no value for the prospective passenger. After the response of users to the new services is analyzed, conclusions for the operational design of the system are presented.

Traffic Flow Model

Bus rapid transit (BRT) systems are becoming increasingly popular in cities worldwide because of their ( a) efficiency and reliability advantages over traditional bus service and ( b) cost advantages over rail transit systems. As transportation decision makers consider the implementation and planning of BRT systems, it is important that they be able to analyze different operational components of these systems. This paper describes an analytical five-phase BRT traffic flow model that is able to model the movement of a bus throughout an entire BRT corridor and network. The five-phase model includes ( a) a queuing model to determine the time a bus spends waiting for access to the loading area, ( b) an access time model to determine the time that it takes a bus to access a loading area position from the queue when a loading position becomes available, ( c) a nonlinear dwell time model to determine the time that a bus spends at a loading area position, and ( d and e) a two-part model of the following behavior of buses between bus stations, dependent on whether there is a bus between the following bus and the approaching station. The five-phase BRT traffic flow model provides a comprehensive modeling framework for a networkwide simulation of a separate right-of-way BRT system. The model builds on research in the areas of car-following (and more recently bus-following) models, dwell time models, and bus station queuing models.
