The aim of this studyto know the strategy law enforcement in suppressing traffic accidents that result death at Mojokerto City Police, to find out factors support and hinder Police death, solutions obstacles an effort suppress resulting death. approach method used is juridical normative socio-logical method, specifications research are descriptive analytical, population sampling methods all obj...

The current paper deals with the debate over centralization versus decentralization in road safety management, and specifically traffic law enforcement. We address case study of Spain, where a single acquis is enforced by two systems: policing decentralized for some regions national all others. Our econometric findings reveal that Spanish centralized present better figures, which might be usefu...

In 2011, China implemented a more severe drunk-driving law. This study evaluated the effectiveness of the law on road traffic morbidity and mortality attributed to alcohol use. Data were from two open-access data sources, the Global Burden of Disease (GBD) 2015 update and police data. Poisson regression examined the significance of changes in morbidity and mortality. Large gaps in crude death e...

Understanding the TCP congestion control mechanism from a global optimization point of view is not only important in its own right, but also crucial to the design of other transport layer traffic control protocols with provable properties. In this paper, we derive a global utility function and the corresponding optimal control law, known as TCP control law, which maximizes the global utility. T...

Peer-to-peer (P2P) file-sharing applications generate a large part of today's Internet traffic. The large volume of this traffic (thus high potential caching benefits) and the large cache sizes required (thus nontrivial costs associated with caching) only underline that efficient cache replacement policies are important in this case. File popularity in P2P file-sharing networks does not follow ...

We present a novel approach for the measurement and estimation of network traffic management between network nodes in heterogeneous environment. This research investigates performance evaluation of network traffic on heterogeneous services and technologies environment. We propose an enhanced equation to evaluate the performance of network traffic management via Little Law and Queuing theory to ...

This paper introduces a vehicle identification system (VIS) by automated Korean license plate reading. Generally, an automatic violator detection system requires various techniques, including sensing, image acquisition, license plate reading, communication, database, and so on. We developed all of such techniques and integrated into an intelligent law enforcement system against traffic violatio...

The paper studies a class of conservation law models for traffic flow on a family of roads, near a junction. A Riemann Solver is constructed, where the incoming and outgoing fluxes depend Hölder continuously on the traffic density and on the drivers’ turning preferences. However, various examples show that, if junction conditions are assigned in terms of Riemann Solvers, then the Cauchy problem...

We consider an hyperbolic conservation law with discontinuous flux. Such partial differential equation arises in different applicative problems, in particular we are motivated by a model of traffic flow. We provide a new formulation in terms of Riemann Solvers. Moreover, we determine the class of Riemann Solvers which provide existence and uniqueness of the corresponding weak entropic solutions...
