Effect of passing zone length on operation and safety of two-lane rural highways in Uganda
IATSS Research, 2017 This paper presents a methodology to assess the effect of the length of passing zone on the operation and safety of two-lane rural highways based on the probability and the rate of passing maneuvers ending in a no-passing zone.

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.

Looking for Trouble: Pre‐Intervention Monitoring in Human and AI Driver Training
Symbolic Interaction, EarlyView.We compare two types of situations involving monitoring of car driving: a driving instructor overseeing a trainee driver and a safety driver overseeing the performance of autonomous vehicle (AV) software. Our focus is on instances of monitoring that precede (1) interventions that are aborted before impacting the driving and (2) actual interventions on ...

Influence of horizontal alignment elements on operating speed of vehicles on two-lane highways
Frontiers in Future TransportationEarlier studies acknowledged that the design speed does not principally assure consistency in the design of highway geometric elements. Methodologies for estimating operating speeds are limited to specific or local traffic conditions and design standards,

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 ...

Wildlife Biology, EarlyView.Worldwide, transportation agencies have been involved in road mitigation efforts to reduce road mortality and promote connectivity of endangered species. Baseline data on how mammals respond to highway construction, however, are rarely collected in road mitigation and monitoring studies, including in the USA.

Wildlife Letters, EarlyView.Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.

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 ...
