Like signals in a road network, queuing and waiting are unavoidable at ferry terminals. However, a reliable technology does not exist to measure and communicate waiting times. This research tested the feasibility of applying license plate recognition (LPR) technology to track vehicles and estimate waiting times at ferry terminals. The LPR camera sampling rate, capture rate, read rate, and match rate were adopted as measurements of effectiveness. Based on field data collected over a week at one of the busiest ferry terminals in North Carolina, this research revealed that the tested LPR camera had a sampling rate of 84.2%; the average capture rate and read rate were 84.3% and 87%, respectively. The match rate was found to be 79.4%, which is significantly higher than other commonly used data collection technologies such as Bluetooth devices. For the waiting time distribution, this research found that travelers tended to experience long waiting times during midweek days, particularly during the midday period. Additionally, the demand was found to be the primary factor for wait times during the midday peak period, and travelers’ arrival time in terms of proximity to the scheduled ferry departure time was recognized as the key factor for waiting time during early morning and later evening nonpeak periods.}, number={9}, journal={JOURNAL OF TRANSPORTATION ENGINEERING PART A-SYSTEMS}, author={Yang, Guangchuan and Coble, Daniel and Vaughan, Chris and Peele, Catherine and Morsali, Atefeh and List, George F. and Findley, Daniel J.}, year={2022}, month={Sep} } @article{warchol_rouphail_vaughan_kearns_2019, title={Queue-Based Guidance for Signalization Consideration at Two and Three-Legged Intersections}, volume={2673}, ISSN={["2169-4052"]}, DOI={10.1177/0361198119847468}, abstractNote={ This research collected and analyzed gap acceptance in North Carolina to develop a data-driven method for determining the need for considering additional signalization analysis at intersections with fewer than four legs. This method can be used for movements that merge with or cross two lanes of oncoming traffic. It is intended to provide guidance and support to traffic engineers in their decision-making process. Charts are provided to determine the expected 95th percentile queue lengths for left-turn, right-turn, and U-turn movements crossing or merging with two lanes of conflicting traffic. This situation is typically present along four-lane roadways where a one-way primary movement opposes either a minor road right-turn movement or a left-turn movement, or in the case of a median U-turn opening. Adjustment factors to the conflicting flowrate were developed to account for the presence of upstream signalized intersections. This method less frequently recommends further signal consideration when compared with the Manual on Uniform Traffic Control Devices peak hour warrant, but is similar to the delay-based level of service D/E threshold for two-way stop-controlled intersections in HCM6 Chapter 19. }, number={10}, journal={TRANSPORTATION RESEARCH RECORD}, author={Warchol, Shannon and Rouphail, Nagui M. and Vaughan, Chris and Kearns, Brendan}, year={2019}, month={Oct}, pages={416–426} } @article{vaughan_jagadish_bharadwaj_cunningham_schroeder_hummer_findley_rouphail_2016, title={Long-term monitoring of wrong-way maneuvers at diverging diamond interchanges}, number={2484}, journal={Transportation Research Record}, author={Vaughan, C. and Jagadish, C. and Bharadwaj, S. and Cunningham, C.

More than 300 people from 61 communities participated in the surveys, which were held in six locations: Asheville, Burlington, Charlotte, Jonesville, Rocky Mount, and Wilmington. The purpose of the roadway review was twofold: to determine the expectations for the condition of North Carolina highways and to identify the features that North Carolinians believe are most important on different types of highways. Surveys were completed during both daytime and nighttime hours and covered many roadway maintenance aspects, such as pavement, landscaping and mowing practices, signage, retroreflectivity, and shoulders. Regression equations are also provided to predict the overall satisfaction of condition, safety, and appearance by each individual roadway type. }, number={2361}, journal={TRANSPORTATION RESEARCH RECORD}, author={Cunningham, Christopher M. and Chang, Jeffrey C. and Findley, Daniel J. and Vaughan, Christopher L. and Martin, James and Hekele, Aaron and Tatham, Chris}, year={2013}, pages={25–34} } @article{findley_cunningham_schroeder_vaughan_fowler_2012, title={Structural and safety investigation of statewide performance of weathered steel beam guardrail in North Carolina}, number={2309}, journal={Transportation Research Record}, author={Findley, D.
