Intersection Sight Distance Characteristics of Turbo Roundabouts [PDF]

open access: yesDesigns, 2021
A turbo roundabout uses spiral circulatory roads for effectively counteracting the problems faced in modern multilane roundabouts. First developed in 1996, the turbo roundabout has an advantage over the conventional roundabout regarding capacity and safety.

Reliability Analysis of Intersection Sight Distance at Roundabouts [PDF]

open access: yesInfrastructures, 2020
This paper presents a reliability-based method for the design of intersection sight distance (ISD) at traffic roundabouts using the linear and nonlinear deceleration profiles of the entry vehicles. The reliability method is based on the first-order second moment method which is simple and relatively accurate compared with advanced methods.

Intersection sight distance evaluation through a comprehensive review and novel measurement framework

open access: yesDiscover Civil Engineering
Intersection sight distance (ISD) is a key factor in allowing drivers to make appropriate maneuvering and crossing decisions at intersections, contributing to safer road environments. Limited visibility at intersections has been associated with increased

Sight distances at unsignalized intersections: a comparison of guidelines and requirements for human drivers and autonomous vehicles [PDF]

open access: yesArchives of Transport, 2021
Many traffic accidents are caused by unforeseen and unexpected events in a site that was hidden from the driver's eyes. Road design parameters determining required visibility are based on relationships formulated decades ago. It is worth reviewing them from time to time in the light of technological developments.

Safety Assessment of Urban Intersection Sight Distance Using Mobile LiDAR Data [PDF]

open access: yesSustainability, 2021
This paper proposes an automated framework that utilizes Light Detection and Ranging (LiDAR) point cloud data to map and detect road obstacles that impact drivers’ field of view at urban intersections. The framework facilitates the simulation of a driver’s field of vision to estimate the blockage percentage as they approach an intersection. Furthermore,

Evaluation of the Intersection Sight Distance at Stop-Controlled Intersections in a Mixed Vehicle Environment

open access: yesWorld Electric Vehicle Journal
The introduction of autonomous vehicles (AVs) on roadways will result in a mixed vehicle environment consisting of these vehicles and manual vehicles (MVs). This vehicular environment will impact intersection sight distances (ISDs) due to differences in the driving behaviors of AVs and MVs. Currently, ISD design values for stop-controlled intersections

Examining the Effects of Sight Distance, Road Conditions, and Weather on Intersection Crash Severity: A Random Parameters Logit Approach with Heterogeneity in Means and Variances

open access: yesSafety
Intersections represent critical crash locations on road networks necessitating targeted safety interventions. This study employs a random parameters ordered logit (RPOL) model with heterogeneity in means to analyze injury severity contributing factors ...

Modelling of Three-Dimensional Intersection Sight Distance [PDF]

open access: yesTransportation Research Part A: Policy and Practice, 2021
Intersection sight distance(ISD) is an important design element. Each intersection has a potential for several different types of vehicular conflicts that can be greatly reduced through the provision of proper sight distance. Current guidelines do not adequately address sight distance requirements for intersections located on horizontal curves alone or

Review of United States research and guidelines on left turn lane offset: Unsignalized intersections and signalized intersections with permitted left turns

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2022
The purposes of this paper are to better understand the design and impact of left turn lane offset and provide state transportation agencies recommendations on best practices and alternative design options to address left turn sight line obstruction ...

LOS Signal Identification Based on Common Chord Intersection Point Position Deviation from MS in Target Localization

open access: yesApplied Sciences, 2023
Target localization has been a popular research topic in recent years since it is the basis of all kinds of location-based applications. For GNSS-denied urban or indoor environments, the localization method based on time-of-arrival (TOA) is one of the ...
