<p>Activity-based microsimulation models are gaining increasing attention from MPOs around the country. These models earn their reputation by having shown their theoretical superiority over the traditional four-step models. The NYBPM (New York Best Practice Model) model is one of a relatively few operating activity-based microsimulation models in the country and thus provides us a working platform to test their practical advantages over the traditional four-step models. We accomplish this goal by examining the sensitivity of the model in response to changes in the input.

Road traffic crashes and injuries constitute major health, economic, and developmental challenges to African countries. For its 4 per cent of the world?s motor vehicles, the fatalities on African roads exceed 10%. With further motorization, the number of road traffic crashes, injuries and fatalities are expected to continue to grow. The road carnage has severe impact on the human, social and economic development. The present study intends to update the status, trends, causes, existing countermeasure, and issues in traffic safety, facing African countries.

<p>As traffic congestion builds up rapidly in recent years especially in urban areas like the New York City, Congestion Pricing (CP) has been proposed and widely implemented, which has now become &#39;the single most viable and sustainable approach to reducing traffic congestion (1).&#39; One form of CP is called Second-Best Toll Pricing (SBTP), i.e. imposing appropriate tolls on selected locations (such as bridges or tunnels) of a transportation network so that congestion can be reduced. Research on SBTP is rich and still growing.

<p>Warm mix asphalt (WMA) technologies have attracted great interest in the field of pavement engineering due to its potential energy savings and environmental benefits. As one of the most popular WMA processes, Advera? utilizes zeolite to greatly reduce the production temperature of pavement without compromising the performance of the mixture. However, due to the lack of a comprehensive rheological characterization, the existing specifications cannot provide the optimum temperature and additive proportion for specific binder or aggregate types.

<p>Through support of a University Transportation Research Center Faculty Development Minigrant an invest igation was made into the use of RFID based sensing technologies for transportation purposes. Transportation applications would potent i a l ly include the wireless detection of overweight t rucks, remote and automated emissions monitoring of vehicles, corrosion of infrast ructure and transportation security applications.

<p>The purpose of this project was to study the feasibility of a regional approach to rail transit training in the New York metropolitan area and to recommend a means for implementing such a cooperative training effort. The first part was to study the existing training at the five agencies, to document the training needs of each agency, and to determine mutual training needs that could be addressed on a regional basis.

<p>The air travel industry is in turmoil. Bankruptcies of commercial air carriers has become commonplace. Increasing fuel costs make profitability wishful thinking for many carriers, and many cities are losing scheduled air service as carriers focus on only the most profitable routes. Complaints about delays are the norm. The benefits that will result from technological improvements are years away. Many in both the private and public sectors describe the system as &#39;broken&#39; and call out for changes in national aviation policy.

In the New York metropolitan region, there are over 50,000 people employed in rail transit in five separate public rail agencies, including both heavy rail (sometimes called subway or rapid rail) and commuter rail. This represents approximately two thirds of all rail transit employees in the United States. Each of these five agencies is struggling to provide quality service while containing their costs.

<p>New York?s northern and western borders with Canada have long served as important commercial and tourist gateways for the entire United States. With recent and projected growth in cross-border travel, and heightened security concerns arising from the terrorist attacks on September 11, 2001, the transportation infrastructure in the border regions is being pushed to its limits.
