In July of 2017, the Boston Globe published an article titled “Driving Through These Towns in Mass.? Watch Your Speed” [1] that among other elements, included a series of maps and a brief summary identifying Massachusetts municipalities that had the most traffic violations issued between 2010 and 2016. The article stated that the Massachusetts State Police issued the most citations of any police agency in the state, and that many citations were given along major highways, especially Interstate 90 and major highways and routes that intersect it, such as Interstate 84 and Route 20. Despite the public attention-grabbing nature of …

Left-turns are the most complex maneuvers in a signalized intersection. Based on the flow of the traffic volume through a given intersection, the left-turn phasing may be controlled in various fashions such as: protected only, permissive only, and protected/permissive. Following the introduction of the flashing yellow arrow (FYA) to the 2009 Edition of the Manual on Uniform Traffic Control Devices (MUTCD), many state agencies have implemented these indications for their left-turn permissive movements. Similar to the existing circular green (CG) permissive indication, the FYA requires drivers to yield to oncoming vehicles before making their left-turn. However, given the novelty of …

Driver Performance Due To Unmanned Aerial System Applications In The Vicinity Of Surface Transportation, Alyssa M. Ryan
Transportation Engineering Masters Projects
Unmanned aerial systems (UAS), or drones, have become increasingly utilized for a myriad of applications in the vicinity of the roadway and can offer a low-cost alternative to many labor-intensive data collection techniques, including infrastructure inspection, roadway marking data collection, and more. To collect much of this data with a desired degree of accuracy, UAS must be flown near moving vehicles, pedestrians, and/or bicyclists. However, UAS, and their pilot/crew, have the potential to be a distraction to drivers. A study by Hurwitz et al. suggests that UAS operations are more distracting to drivers as the UAS traverses closer to the …

Traffic Control Devices (TCDs) are integral to driver-to-infrastructure (D2I) and vehicleto- infrastructure (V2I) interactions. The non-conformation (or non-perception) with signage on the part of the driver leads to several compounded safety problems. The need exists for a more robust, low-cost, and user-centric mechanism of delivering information to the driver that can directly bear on the safety of the driver. Technology has now advanced to the point where we can deliver information from a real-world physical environment to the driver in a non-invasive manner using holographic display [1]. With this rapid advancement in-vehicle display (IVD) technology, the transportation industry must undergo …
Dissecting The Safety Benefits Of Protected Intersection Design Features, Nicholas Campelll
Dissecting The Safety Benefits Of Protected Intersection Design Features, Nicholas Campelll
Transportation Engineering Masters Projects
Protected intersections are an integral component of Complete Street networks and are used to facilitate and delineate the route cyclists should take while traveling along a protected network. The separation from the travel lane of automobiles, however, causes a decrease in driver attentiveness to cyclists. Rates of incidents of cyclists, specifically with right turning vehicles, have increased in recent years, leading to a desire to improve the safety benefits of existing protected intersections to increase the visibility of cyclists and driver awareness. This research used a simulated environment to test the effectiveness of different pavement markings and intersection radii on …
