Cooperative formation and control of autonomous vehicles (AVs) promise increased efficiency safety on public roads. In mixed traffic flow consisting AVs human-driven (HDVs), the prevailing platooning multiple is not only choice for cooperative formation. this paper, we investigate how different formations impact performance from a set-function optimization perspective. We first reveal stability...

The essence of the routing problem in real networks is that the traffic demand from a source to destination must be satisfied by choosing a single path between source and destination. The splittable version of this problem is when demand can be satisfied by many paths, namely a flow from source to destination. The unsplittable, or discrete version of the problem is more realistic yet is more co...

This paper addresses the impacts of Adaptive (Intelligent) Cruise Control (ACC) laws on the traffic flow. Semi-automated vehicles, such as ACC Vehicles, with the capability to automatically follow each other in the same lane, will coexist with manually driven vehicles on the existing roadway system before they become universal. This mixed fleet scenario creates new capacity and safety issues. I...

With the rapid development of smartphones in recent years, we have witnessed an exponential growth of the number of mobile apps. Considering the security and management issues, network operators need to have a clear visibility into the apps running in the network. To this end, this paper presents a novel approach to generating the fingerprints for mobile apps from network traffic. The fingerpri...

Intersection traffic delay research has traditionally placed greater emphasis on the study of through and left-turning vehicles than right-turning ones, which often renders existing methods or models inapplicable to intersections with heavy pedestrian and non-motorized traffic. In the meantime, there is also a need for understanding the relations between different types of delay and how they ea...

We explore the use of directional antennas to improve the performance of broadcasting in ad hoc networks. We investigate both the performance of unicast traffic in the presence of broadcast traffic and the performance of broadcast traffic when mixed with unicast traffic, which is different from previous investigations reported in the literature in which broadcast traffic is investigated in isol...

Currently most optimization methods for urban transport networks (i) are suited for networks with simplified dynamics that are far from real-sized networks or (ii) apply decentralized control, which is not appropriate for heterogeneously loaded networks or (iii) investigate good-quality solutions through micro-simulation models and scenario analysis, which make the problem intractable in real t...

16. Abstract Transportation planners and traffic engineers are faced nowadays with immense modeling challenges arising from several emerging policy, planning, and engineering developments. In fact, the recent emergence of mobile sensing and traffic monitoring technology has provided an unprecedented amount of information and data for traffic analysis, demanding the adaptation of mathematical an...

In this paper, we investigate the performance of an IEEE802.3 shared-bandwidth hub under a mixed data/real-time traffic load. For the regular data nodes we assume an exponentially distributed packet length with a Poisson arrival. For the video sources, we assumed MPEG encoded video sources at 30 frames per second. We used simulation to study the network performance under the above-mentioned loa...
