Roadway transportation lighting is installed for multiple reasons including traffic safety and pedestrian security. Judgments of pedestrian safety and security along roadways are not strictly correlated to specified light levels, but the color of the light source influences pedestrians' judgments as well. In general, the brighter a roadway location appears, the safer and more secure it is judged as being.

The Highway Capacity Manual (HCM) has had a delay-based level of service methodology for signalized intersections since 1985. The 2010 HCM has revised the method for calculating delay. This happened concurrent with such jurisdictions as NYC reviewing the use of the HCM method in their environmental impact regulations (e.g. CEQR process), and concurrent with a dialog in the profession on when it is appropriate to use simulation models in lieu of HCM methods.

The goal of this research is to investigate the effects of road pricing on residential land use choices and to help select pricing policies that foster socially and economically sustainable residential development in urbanized residential areas. Under this goal, a residential land use choice model in logit form with shared aggregated data was developed. The model was designed to assess the impacts of various toll pricing policies and the resulting accessibility on a residential land use choice pattern.

A key indicator of traffic activity patterns is commuting distance. Shorter commuting distances yield less traffic, fewer emissions, and lower energy consumption. This study develops a spatial error seemingly unrelated regression model to investigate commuting distance, and how various influential factors affect commuting distances in ten counties across the U.S. By integrating datasets from the Census Transportation Planning Product (CTPP) and Smart Location Database (SLD), this study acquires rich employment and residence information at the census block group (CBG) level.

Kriging method is a frequently used interpolation methodology in geography, which enables estimations of unknown values at certain places with the considerations of distances among locations. When it is used in transportation field, network distance is a better measurement of distance as traffic follows the network. This report presents the development of the Network Kriging method and demonstrates its application on predicting transit ridership.

In the last several years there has been a surge of interest in fostering more sustainable logistical operations in urban areas. Under the umbrella of the generic term City Logistics, these initiatives try to take advantage of the coordinating power of a municipal government to convince urban delivery companies to participate in collaborative schemes that by reducing truck trips, increasing the utilization of trucks, or both, may reduce the negative externalities associated with urban truck traffic.

In this report, the results of a study on developing a damage detection methodology based on Statistical Pattern Recognition are presented. This methodology uses a new damage sensitive feature developed in this study that relies entirely on modal characteristics, i.e. natural frequencies and mode shapes, directly identified from measurements of the structural response. A procedure for training the damage detection methodology to account for variability induced by operational conditions, i.e.

Since March 1, 2008 there has been a ban on wireless telephone and electronic communication devices in New Jersey while operating a motor vehicle. But from general observation on any roadway, it appears that there are still drivers who are talking on their phones or texting while driving. From 2006 to 2009, NJ crashes, injuries, and deaths for handheld devices have averaged 1837, 769, and 6, respectively, while hands‐free averaged 1570 crashes, 659 injuries, and 3 deaths.
