This research report reviews trends in cycling levels, safety, and policies in large North American cities over the past two decades. We analyze aggregate national data as well as cityspecific case study data for nine large cities (Chicago, Minneapolis, Montréal, New York, Portland, San Francisco, Toronto, Vancouver, and Washington, DC).

Freight origin-destination (OD) matrices are one of the most important data a planner could have, which is why a significant amount of effort, time and money is spent on their estimation. The estimation of OD matrices can be done by: (a) direct sampling methods; and, (b) using secondary data sources such as traffic counts. The latter techniques are referred here as origin-destination synthesis (ODS).

This report explains ways to reduce car usage in order to meet climate targets and how to analyze these effects. Much of the analysis has focused on differences between more compact areas that are more walkable versus more extensive car-dependent areas. Given our interest in physical activity (to combat obesity) we are interested in overall walking similar to studies such as (Berrigan, Troiano 2002) which also evaluated all walking trips jointly.

This study reviewed existing practices in Park and Ride planning, developed a methodology for evaluating candidates, and applied the methodology to the commuter market in New York City. The team identified a set of candidates based on availability for Park and Ride use and transit connectivity. The candidates were evaluated using potential demand, savings, market share, and present value of benefits as performance measurements.

This research def ines the concept of transit under-served areas (TUSA), and argues that with the right policies TUSA residents have a great potential to reduce car dependency and usage and switch to publ i c t ransi t . It focuses on one important but often overlooked pol i cy—residential parking, in reshaping t ravel patterns in TUSA neighborhoods, using the New York Ci ty region as an example. Nine hundred households were randomly selected from a regional household travel survey in the New York City region.

The enormous prevalence and popularity of GPS devices have led to a growth market called Location-based services. These applications, often developed for mobile devices, utilize location information, such as the location of the person accessing the application, and commonly the location patterns of other users. Location-based service is an active area of research, encompassing applications such as supply-chain management, location detection and traffic modeling.

The massive volumes of trajectory data generated by inexpensive GPS devices have led to difficulties in processing, querying, transmitting and storing such data. To overcome these difficulties, a number of algorithms for compressing trajectory data have been proposed. These algorithms try to reduce the size of trajectory data, while preserving the quality of the information. We present results from a comprehensive empirical evaluation of many compression algorithms including Douglas-Peucker Algorithm, Bellman's Algorithm, STTrace Algorithm and Opening Window Algorithms.

<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>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.

This study identifies climate change adaptation strategies and recommends ways of mainstreaming them into planned actions, including legislation, policies, programs and projects in all areas and at all levels within the New York State Department of Transportation (NYSDOT).
