1.      Studying Critical Pedestrian Behavioral Changes for the Safety Assessment at Signalized Crosswalks -017-0. “Pedestrian-vehicle conflicts are one of the most important safety concerns at signalized intersections especially in urban areas. Conflicting vehicles and pedestrians select their maneuvers by predicting the other user behavior.”Behavior; Crosswalks; Pedestrian vehicle interface; Pedestrian-vehicle crashes; Signalized intersections; Speed; Traffic signal timing; Urban areas
2.      Safety Assessment of Backlit Pedestrian Crossing Sign on Stopping Characteristics at Unsignalized Intersection Transportation Research Board 96th Annual Meeting, 2017, 14p2017.   “Traffic engineers regularly choose LED illuminated signs in order to improve safety at locations identified as high risk for crashes. Recent studies have shown that these signs have characteristics that make them more visible and legible than the conventional signs.” Crash causes; Crosswalks; Illuminated traffic signs; Light emitting diodes; Pedestrian movement; Simulation; Stop signs; Unsignalized intersections
3.      Evaluation of Vehicle-to-Pedestrian Communication Displays for Autonomous Vehicles Transportation Research Board 96th Annual Meeting, 2017, 13p 2017.  “Previous work in human-centered design includes development of interfaces that improve driver effectiveness; however, interfaces designed to communicate to pedestrians based on a vehicle’s perceived intent are limited.” Autonomous land vehicles; Crosswalks; Decision making; Midblock crossings; Pedestrian movement; Pedestrians; Proximity detectors; Traveler information and communication systems; Vehicle to infrastructure communications
4.      A Semiparametric Statistical Approach to Evaluate Conflict Severity As a Surrogate for Crashes in the Context Of Pedestrian Safety Transportation Research Board 96th Annual Meeting, 2017, 20p 2017.  “There is growing interest among traffic engineers for using so-called surrogate measures of safety as an alternative to crash counts, especially in contexts where the temporal and/or spatial crash occurrence rate is extremely low.” Crash rates; Crosswalks; Highway safety; Intersections; Mathematical models; Pedestrian safety; Traffic conflicts
5.      Preliminary Investigation of the Effectiveness of High Visibility Crosswalks on Pedestrian Safety Using Crash Surrogates Transportation Research Board 96th Annual Meeting, 2017, 21p 2017.  “Using the Second Strategic Highway Research Program (SHRP2) naturalistic driving study (NDS) data, this paper provides a preliminary evaluation of the effectiveness of high-visibility crosswalks (HVC) in terms of improving pedestrian safety at uncontrolled locations.”Acceleration (Mechanics); Automatic data collection systems; Before and after studies; Behavior; Braking; Crash causes; Crosswalks; Drivers; Linear regression analysis; Logics; Pedestrian safety; Speed; Visibility
6.      A Comparison of Analysis Methods on Staged Pedestrian Crossings at Crosswalks with a Rectangular Rapid Flashing Beacon Transportation Research Board 96th Annual Meeting, 2017, 20p 2017.  “Previous studies of rectangular rapid-flashing beacons (RRFB) have found a wide range of driver yielding rates (19 to 98 percent), even after accounting for variables identified as most influential in the decision to yield.” Alternatives analysis; Analysis of variance; Binomial distributions; Crosswalks; Data analysis; Flashing beacons; Logistic regression analysis; Methodology; Pedestrian movement; Yielding
7.      Predicting Yielding Compliance at Midblock Crossing Areas Based on Roadway, Traffic and Crosswalk Characteristics Transportation Research Board 96th Annual Meeting, 2017, 15p2017.  “A field study was performed to compare the relative effectiveness of various types of traffic control countermeasures commonly utilized at midblock crossing locations.”Compliance; Crosswalks; Drivers; Field studies; Flashing beacons; Mathematical prediction; Midblock crossings; Pedestrian safety; Urban areas; Yielding
8.      Effects of Refuge Island Settings on Pedestrian Safety Perception and Signal Violation at Signalized Intersections Transportation Research Board 96th Annual Meeting, 2017, 16p 2017.  “Pedestrians are the most vulnerable road users and great efforts have been made to find out countermeasures to improve pedestrian safety.”Countermeasures; Crosswalks; Pedestrian safety; Perception; Signalized intersections; Traffic islands; Traffic violations  Intercept surveys
