77 THIS FEATURE PRESENTS A RELAtively unique concept for urban arterial highway interchanges. The interchange has been named the Echelon Interchange because of its symmetrical, but offset, pair of two-phase one-way pair intersections—one elevated over the other. An observer1 noted that the interchange resembled a flying formation used by the U.S. Navy Flight Demonstration Team, the “Blue Angels...

Additive fuzzy systems can control the velocity and the gap between cars in single lane platoons. The system consists of throttle and brake controllers. We first designed and tested a throttle-only fuzzy system on a validated car model and then with a real car on highway I-15 in California. We used this controller to drive the “smart” car on the highway in a two-car platoon. Then we designed a ...

86 1094-7167/03/$17.00 © 2003 IEEE IEEE INTELLIGENT SYSTEMS The first large-scale application of computerized signal control systems, Torontonians brag, was in Metropolitan Toronto during the early 1960s. More recently, changeable-messagesign driver information systems (such as COMPASS, www. mto.gov.on.ca/english/traveller/compass) for freeway control have been introduced in the Greater Toronto...

In the present paper multilane models for vehicular traac are considered. A microscopic multilane model based on reaction thresholds is developed. Based on this model an Enskog like kinetic model is developed. In particular, care is taken to incorporate the correlations between the vehicles. From the kinetic model a uid dynamic model is derived. The macroscopic coeecients are deduced from the u...

Ground-level ozone is a secondary air pollutant that formed by chemical reactions between precursors, including nitrogen oxides (NOx) and hydrocarbon (HC). Highway traffic, which can be controlled traffic operational strategies, one of the main sources atmospheric NOx HC. Managed-lane pricing popularly used freeway management approaches, while its impacts on ground-level ozone-related vehicle e...

The quality-control method is improved and used to identify accident black spots on highway. A neural networks prediction model based on three layers BP network is suggested to predict road traffic accident. The dynamic accident power method for macroscopic evaluation is put forward and the concept of highway accident coefficient is advanced in the method. With large numbers of actual traffic a...

Since changes in trade openness are typically confounded with other factors, it has been difficult to identify the labor market consequences of increased international trade. The advent of the United States Interstate Highway System provides a unique policy experiment, which I use to identify the effect of reducing trade barriers on the relative demand for skilled labor. The Interstate Highway ...

Traffic conditions vary over time, and therefore, traffic behavior should be modeled as a stochastic process. In this study, a probabilistic approach utilizing Autocorrelation is proposed to model the stochastic variation of traffic conditions, and subsequently, predict the traffic conditions. Using autocorrelation of the time series samples of density and flow which are collected from segments...
