Estimating passing sight distances for overtaking truck platoons – Calibration and validation using VISSIM

International Journal of Transportation Science and Technology, 2022
Two-lane highways comprise a substantial proportion of the nation’s highways. One of their critical aspects is the passing sight distance (PSD), which is the minimum distance required for executing a safe passing maneuver using the opposing travel lane ...

Developing a universal tunnel span classification from global tunnel databases

Deep Underground Science and Engineering, EarlyView.
A universal tunnel span classification system is introduced that incorporates tunnel span, cross‐sectional area, typical tunnel types, and intended uses. Representative flatness ratio values are also provided for each span class. The classification is derived from a comprehensive database of 450 tunnel profiles from 47 countries.

Disentangling contract and law: Legal specificity and contractual governance in public–private partnerships

Strategic Management Journal, EarlyView.
Abstract Research Summary This study examines how legal design shapes contractual governance in public–private partnership (PPP). We argue that PPP‐specific laws do not simply strengthen institutional safeguards; by varying in detail, they also alter the flexibility available for project‐level contracting.

COMPARATIVE ANALYSIS OF DOUBLE DEEP Q-NETWORK AND PROXIMAL POLICY OPTIMIZATION FOR LANE-KEEPING IN AUTONOMOUS DRIVING [PDF]

Problems of Information Society
Lane-keeping is a vital function in autonomous driving, important for vehicle safety, stability, and adherence to traffic flow. The intricacy of lane-keeping control resides in balancing precision and responsiveness across varied driving ...

A Survey of Localization Methods for Autonomous Vehicles in Highway Scenarios

Sensors, 2021
In the context of autonomous vehicles on highways, one of the first and most important tasks is to localize the vehicle on the road. For this purpose, the vehicle needs to be able to take into account the information from several sensors and fuse them ...

A realistic two-lane traffic model for highway traffic [PDF]

Journal of Physics A: Mathematical and General, 2002
A two-lane extension of a recently proposed cellular automaton model for traffic flow is discussed. The analysis focuses on the reproduction of the lane usage inversion and the density dependence of the number of lane changes. It is shown that the single-lane dynamics can be extended to the two-lane case without changing the basic properties of the ...

Are client ties pre‐entry resources? Performance implications of client tie diversification

Strategic Management Journal, EarlyView.
Abstract Research Summary This study investigates client tie diversification, where firms enter markets with existing clients. Recognizing the theoretical basis for both positive and negative performance implications, the paper adopts a question‐driven approach and discovers a strong negative correlation between client tie diversification and firm ...

Exploring operational characteristics of stop-controlled T-intersections on rural two-lane highways with passing lanes

International Journal of Transportation Science and Technology
Left turn traffic at unsignalized T-intersection on undivided rural two-lane high-speed highways poses both operational and safety challenges. More complexities are faced by through drivers in the same direction as the stopped or slowed down left-turn ...

Evaluation of speed–flow characteristics on two-lane highways with mixed traffic

Transport, 2017
The HCM (Highway Capacity Manual 2010) classifies two-lane rural highway that passes through developed areas as ‘Class III’ and suggests using Percent Free-Flow Speed (PFFS) as performance measure to define Level Of Service (LOS).
