Background: The noise caused by traffic is an increasingly prominent feature of urban environments. However, limited studies have been focused on the assessment of exposure-response relationship between road traffic noise exposure and driving behaviors in Iran. The present study aimed to investigate the prevalence of the violations caused by road traffic noise exposure in Qazvin, Iran. Methods...

The core methodology of the Highway Capacity Manual (HCM) 2010 for freeway analyses is based on Free-Flow Speed (FFS). Moreover, weaving segments are major elements of freeway facilities that form where two one-way traffic streams intersect by merging and diverging maneuvers. Hence, this study used three different methods to compute FFS of a ramp-weaving segment, and then employed the proposed ...

Sampling techniques play a key role in achieving efficient network measurements by reducing the amount of traffic processed while trying to maintain the accuracy of network statistical behavior estimation. Despite the evolution of current techniques regarding the correctness of network parameters estimation, the overhead associated with the volume of data involved in the sampling process is sti...

Urban traffic flow is a complex system. Behavior of an individual driver can have butterfly effect which can become root cause of an emergent phenomenon such as congestion or accident. Interaction of drivers with each other and the surrounding environment forms the dynamics of traffic flow. Hence global effects of traffic flow depend upon the behavior of each individual driver. Due to several a...

We consider a WCDMA system with real time (RT) calls that have dedicated resources, and data non-real-time (NRT) calls that share system capacity. We apply reservation of some resources for the NRT traffic and assume that this traffic is further assigned the resources unused by RT calls. The grade of service (GoS) of RT traffic is also controlled in order to allow for handling more RT calls dur...

Multiagent-based simulations are a key part of several research fields. Multiagent-based simulations yield multiagent societies that well reproduce human societies, and so are seen as an excellent tool for analyzing the real world. A multiagent-based simulation allows crowd behavior to emerge through interactions among agents where each agent is affected by the emerging crowd behavior. The inte...

Computer and network administrators are often confused or uncertain about the behavior of their networks. Traditional analysis using IP ports, addresses, and protocols are insufficient to understand modern computer networks. Here we describe NetADHICT, a tool for better understanding the behavior of network traffic. The key innovation of NetADHICT is that it can identify and present a hierarchi...

The characterization and quantitative description of Internet traffic is becoming increasingly important in light of the rapid growth being observed in the size and usage of the network. Modeling of modern teletraffic and large telecommunications networks with fractal stochastic processes has been investigated by analyzing traffic measurements collected on the “Federico II” university WAN link ...

Title of Document: TRAFFIC ANALYSIS ON CUMULATIVE LAND DEVELOPMENT AND TRANSPORTATION RELATED POLICY SCENARIOS Zheng Zhu, Master of Science, 2014 Directed By: Professor Lei Zhang, Department of Civil and Environmental Engineering Numerous methods have been developed to evaluate the impact of land developments and transportation policies on transportation infrastructures. But traditional approac...

Drivers in urban neighborhoods who patrol streets, seeking inexpensive on-street parking create a significant fraction of measured traffic congestion. The pool of drivers patrolling at any time can be modeled as a queue, where ‘queue service’ is the act of parking in a recently vacated parking space and queue discipline is SIRO – Service In Random Order. We develop a queueing model of such driv...
