A narrow front FOV (≤ 85°) was associated with a significant 49.6% increase in the odds, compared with a wide FOV (> 90°). A long front NVP distance (> 9 m) was associated with a significant 35.3% increase in the odds, compared with a short distance (≤ 6 m). No significant associations were found between visibility metrics and right-turning pedestrian crashes. Larger driver-side blind zones, longer front NVP distances, and narrower front FOVs increased risk of left-turning pedestrian crashes. Effects of A-pillars, side mirrors, hoods, and windshields on blind zone sizes and front NVP distances were also validated. Findings could help automakers improve safety for road users outside vehicles with changes in vehicle design to enhance drivers’ direct vision and improvements to AEB technology to address vehicle-turning conflicts.]]> Thu, 18 Jun 2026 16:34:46 GMT https://trid.trb.org/View/2709661 Real-time identification of cooperative perception necessity in road traffic scenarios https://trid.trb.org/View/2667137 Tue, 26 May 2026 09:40:58 GMT https://trid.trb.org/View/2667137 Boston Blind Zone Safety Initiative: Current Fleet Analysis, Market Scan, and Proposed Direct Vision Rating Framework https://trid.trb.org/View/2692319 Wed, 15 Apr 2026 10:36:10 GMT https://trid.trb.org/View/2692319 MTRCP: Multimodal Two-Level Fusion Architecture for Roadside Cooperative Perception https://trid.trb.org/View/2625411 Mon, 23 Feb 2026 11:23:12 GMT https://trid.trb.org/View/2625411 Assessment of the stopping for right-turning large vehicles policy in Nanjing: Effectiveness and determinants https://trid.trb.org/View/2604565 0.05). Regression analysis quantified four critical determinants: absence of motorized/non-motorized segregation (OR=1.82, + 81.6% severity odds), elevated stop-line speeds (OR=1.32, + 31.9%), failure to yield (OR=2.45, + 145%), and crossing the street within the zebra crossing (OR=0.19, -81.0%). The analysis demonstrates that infrastructural deficiencies and behavioral non-compliance outweigh the policy's standalone impact. Based on these findings, the study proposes a holistic optimization framework integrating physical separation measures, enhanced signage, dynamic traffic signal adjustments, and data-driven enforcement strategies. Methodologically, this study innovatively combines unsupervised learning for conflict categorization, providing a scalable framework for evaluating urban traffic policies. This research underscores the necessity of multi-dimensional interventions-spanning infrastructure, enforcement, and public education-to achieve sustainable improvements in intersection safety. The findings offer actionable insights for policymakers to refine regulatory measures and enhance road safety in rapidly urbanizing environments.]]> Mon, 22 Dec 2025 16:07:16 GMT https://trid.trb.org/View/2604565 Vehicle blind zones and pedestrian safety at intersections: Identifying high-risk scenarios using mathematical simulations https://trid.trb.org/View/2617070 Wed, 19 Nov 2025 17:09:39 GMT https://trid.trb.org/View/2617070 Assessing advanced driver assistance systems in police vehicles under demanding conditions https://trid.trb.org/View/2594127 Tue, 18 Nov 2025 11:04:19 GMT https://trid.trb.org/View/2594127 Using Head-Mounted Virtual Reality to Measure Dynamic Driver Sight Distances and Blind Spots https://trid.trb.org/View/2625595 Mon, 17 Nov 2025 14:56:41 GMT https://trid.trb.org/View/2625595 The Effect of Front Pillar Blind Spots on Visual Behavior at Intersections in an Immersive Driving Simulator https://trid.trb.org/View/2582070 Fri, 26 Sep 2025 13:39:58 GMT https://trid.trb.org/View/2582070 Are directional or non-directional hazard warnings more helpful for drivers with homonymous visual field loss? https://trid.trb.org/View/2587418 Mon, 22 Sep 2025 08:48:46 GMT https://trid.trb.org/View/2587418 Evaluating defensive driving behaviour based on safe distance between vehicles: A case study using computer vision on UAV videos at urban roundabout https://trid.trb.org/View/2549286 Mon, 19 May 2025 15:47:55 GMT https://trid.trb.org/View/2549286 Where a glance is an action : drilling visual routines in driver training https://trid.trb.org/View/2534249 Fri, 04 Apr 2025 15:15:43 GMT https://trid.trb.org/View/2534249 Identifying High-Risk Situations in Right-Turn Phase of Heavy-Duty Vehicles Using Naturalistic Driving Data https://trid.trb.org/View/2518915 Mon, 17 Mar 2025 09:18:07 GMT https://trid.trb.org/View/2518915 Dash Mount Flat-Panel mmWave Antenna With Blind Spotless 2-Dimensional Coverage https://trid.trb.org/View/2506172 Thu, 27 Feb 2025 10:47:05 GMT https://trid.trb.org/View/2506172 Workplace road safety education: truck safety and blind spots awareness project https://trid.trb.org/View/2509196 Thu, 13 Feb 2025 09:05:58 GMT https://trid.trb.org/View/2509196
