In highly populated urban zones, it is common to notice headway deviations (HD) between pairs of buses. When these events occur in a bus stop, they often cause bus bunching (BB) in the following bus stops. Several proposals have been suggested to mitigate this problem. In this paper, we propose to find BBS (Bunching Black Spots) – sequences of bus stops where systematic HD events cause the form...

The provision of urban public transport in Indonesia is not free of problems. Some of the problems include: an overall lack of capacity, lack of quality and choice, severe traffic congestions and insufficient fund to renew and repair vehicles. Generally, the comfort and quality of the city bus is poor, and many of the vehicles are dilapidated and dirty. Surveys were carried out in the city of Y...

SECTION 1 INTRODUCTION Overview Bus Rapid Transit (BRT) has emerged as a viable option to enhance transportation capacity and provide increased levels of mobility and accessibility. BRT systems vary from one application to another but all provide a higher level of service than traditional bus transportation. Service on BRT systems is generally faster than regular bus service because the buses m...

In this paper, system planning network is formulated with mixed-integer programming. Two meta-heuristic procedures are considered for this problem. The cost function of this problem consists of the capital investment cost in discrete form, the cost of transmission losses and the power generation costs. The DC load flow equations for the network are embedded in the constraints of the mathematica...

The Simultaneous Optical Multiprocessor Exchange Bus (SOME-Bus) is a low-latency, high-bandwidth interconnection network that directly links arbitrary pairs of processor nodes without contention, and can efficiently interconnect over one hundred nodes. Each node has a dedicated output channel and an array of receivers, with one receiver dedicated to every other node’s output channel. The SOME-B...

increasing urban network has both positive (accessibility) and negative (air pollution) impacts. in this research air quality is chosen as key elements with respect to their critical roles in quality of life and urban health. the overall objective of this study is to develop a mathematical model to plan appropriate locations for residential land uses and urban transportation network development...

Deregulation of power system in recent years has changed static security assessment to the major concerns for which fast and accurate evaluation methodology is needed. Contingencies related to voltage violations and power line overloading have been responsible for power system collapse. This paper presents an enhanced radial basis function neural network (RBFNN) approach for on-line ranking of ...

This article presents a study on the perception of fear related to the use of three different types of urban furniture, qualitatively evaluated based on interviews while people were using them in the city of Porto Alegre, Brazil: the bus shelter, the playground, and the gymnastic equipment. The fear related to the lack of safety of the urban space was associated with the use of the three types ...

The trend towards distributed, networked embedded systems is changing the way power should be managed. Power consumed by bus and network interfaces now matches if not surpasses that of the CPU and is thus becoming a prime candidate for reduction. This paper explores the energy-efficient bus topologies as a new technique for global power optimization of embedded systems that are interconnected b...
