Design of a cooperative overtaking algorithm for platoons on freeways
… total travel time is significantly increased. Overtaking as a whole platoon is a complicated maneuver and there is no communication-based algorithm for this task so far. Therefore, we design such a cooperative overtaking algorithm for platoons on freeways. The algorithm can decide, depending on …

Autonomous Racing and Overtaking for the Voyager Unmanned Ground Vehicle
… successfully performs autonomous racing and overtaking. The primary vehicle navigates the racetrack with minimum lap times while maintaining safe minimum separation distances between the vehicle and the obstacle during overtaking manoeuvres.

Characterizing Bicyclists Behavior in Overtaking Scenarios Over Different Road Infrastructures
… crash scenario occurs when a vehicle performs an overtaking maneuver. It is crucial to find effective strategies to mitigate these crashes. Vision Zero aims to eliminate all traffic fatalities and disabling injuries by the year 2050 through the implementation of the safe system approach. One of …

Development of a full-stack RoboRacer autonomous racing system capable of overtaking in a head-to-head race
… platform, capable of detecting, tracking, and overtaking opponent vehicles in multi-vehicle racing scenarios. The system integrates three primary modules: perception, planning, and control, following the classical “See-Think-Act” paradigm. In the perception module, Monte Carlo localisation …

Characterizing Hydrodynamic Interactions of Underwater Vehicles in Close Proximity Using an Identical Ellipse Pair
… up to four times the value of drag. An overtaking maneuver was investigated by introducing a relative velocity between the ellipses. When both ellipses were moving, the lift was repulsive throughout the maneuver. The mean drag of the slower ellipse was mostly unaffected; although the …

Autonomous aggressive driving: theory & experiments
… maneuvers in different scenarios such as highway overtaking and off-road rally racing, which are referred to as ``aggressive'' driving in the context of this dissertation. By mimicking expert driving styles, one expects to be able to improve the vehicle's active safety and traffic efficiency in …

Steady and unsteady waves generated by a moving body and multiple bodies
… et al., 2008);;When a ship is moving during overtaking (or being overtaken) or passing other ships in a dense shipping traffic environment. The interaction between ships will initiate the unsteady forces/moments.;The aforementioned unsteady effects are associated with the unsteady waves on …

Towards a Comprehensive Bicycle Motion Behavior Model and Naturalistic Cycling Dataset
… a lateral motion strategy; thus allowing for overtaking maneuvers and lateral bicycle movements. For the most part, the following strategy of the FR model remains valid for modeling the longitudinal motion of bicycles except for the activation conditions of the collision avoidance strategy …

Heterogene Sensordatenfusion zur robusten Objektverfolgung im automobilen Straßenverkehr
… perspective is changing - which is typical for overtaking manoeuvres. The advantages of the proposed algorithms will be demonstrated on the basis of real sensor data.

Adequacy of minimum passing sight distances for completing or aborting the passing maneuver
Overtaking and passing maneuvers on two-lane rural roads is still one of the most complex situations drivers are faced with in everyday driving. In passing, drivers must judge the speed, acceleration and deceleration capabilities of their own vehicle, that of the impeding vehicle and the speed and …

Fresh Squeezed: The Dilemma of Local Food Production Along Colorado's Front Range Urban Corridor
… and Taylor 2006). Urban development, however, is overtaking agricultural areas as cities grow towards each other and spread out along transportation networks (Acevedo and Taylor 2006). Unfortunately, the same rich, flat, irrigated soil used to grow food is also favored by land developers and home …

Ramp control strategies and geometric design implications of high-speed automated transportation systems
… traffic flow model is utilized to generate a non-overtaking, continuous traffic stream with automatic acceleration/ deceleration characteristics of the smart cars to fulfill the needs of a high-speed flow under controlled headway and optimized density conditions. The orientation, shape, and …

Decolonising the Informal: Discourse, Everyday Life, and the Politics of Urbanisation in Windhoek, Namibia
… and ‘informal settlements’, which are rapidly overtaking formal urbanisation processes inherited from colonial times. All the while, conventional professional spatial practices remain structurally elitist and seem ineffectual in settings of ‘urban informality’, which largely overlap with the …

Investigating and Characterising the Impact of Vehicle Interfaces on Situation Awareness
… the cost of task switching, but impacted overtaking behaviour. Supporting the DRA, while successful for Lane-keeping, did not operate as intended. Drivers were not able to adequately use concurrent feedback due to not achieving a skilled level of behaviour. Finally, increased awareness …

Intent-aware collision avoidance for autonomous marine vehicles
… mode intent, in which the give-way vessel in an overtaking or crossing scenario communicates its intent to maneuver in a certain direction with respect the stand-on vessel, and discrete trajectory intent in which vehicles communicate projected future positions. Simulations and on-water …

Predictive modeling and socially aware motion planning in dynamic, uncertain environments
… norms, such as passing on the right and overtaking on the left. The proposed methods are tested on hardware, and are shown to enable fully autonomous navigation at the average human walking pace through a pedestrian-rich environment.
