Eco-driving is one of the most effective control strategies to enable energy management for urban traffic. However, existing eco-driving still have two shortcomings: (i) these lack consideration lateral decision-making; (ii) their performance deteriorates when a controlled vehicle encounters traffic queues at signalized intersection. To overcome shortcomings, this paper proposes an innovative s...

At present, there are many methods to construct a vehicle driving cycle, such as the micro-trip-based method and Markov chain method. Different have different advantages disadvantages. To compare these methods, this paper uses method, combining micro-trips chains representative cycle of Xi’an urban bus based on data No.2 bus. Firstly, is collected preprocessed. Then, cycles constructed methods....

Objective The goal of this thesis is to determine the feasibility of a regenerative braking system (RBS) on a school bus and to subsequently develop and test a prototype system. Motivation It is proposed that a regenerative braking system be utilized on a school bus to improve fuel efficiency and reduce exposure of children to diesel particulates. The primary benefit of a RBS is a decrease in t...

Traffic-related air pollution in urban areas contributes significantly to commuters' daily PM2.5 exposures, but varies widely depending on mode of commuting. To date, studies show conflicting results for PM2.5 exposures based on mode of commuting, and few studies compare multiple modes of transportation simultaneously along a common route, making inter-modal comparisons difficult. In this study...

The power dissipation associated with driving data busses can be significant, especially considering the increasing component of inter-wire capacitance. Previous work on bus encoding has focused on minimizing transitions to reduced power dissipation. In this paper, it is shown that transition reduction is not necessarily the best approach for reducing power when the effects of inter-wire capaci...

NStrace is a bus-driven hardware trace facility developed for the PowerPC@ family of superscalar RlSC microprocessors. It uses a recording of activity on a target processor's bus to infer the sequence of instructions executed during that recording period. NStrace is distinguished from related approaches by its use of an architecture-level simulator to generate the instruction sequence from the ...

A single-chip CMOS optical microspectrometer containing an array of 16 addressable Fabry–Perot etalons (each one with a different resonance cavity length), photodetectors, and circuits for readout, multiplexing, and driving a serial bus interface has been fabricated in a standard 1.6m CMOS technology (chip area 3.9 4.2 mm). The result is a chip that can operate using only four external connecti...
