More Effective Use of Urban Space by Autonomous Double Parking

Abstract

The new capabilities of autonomous cars can be used to mitigate to a large extent safety concerns and nuisance traditionally associated with double parking. In this paper double parking for autonomous cars is proposed as a new approach to temporarily increase parking capacity in locations in clear need for extra provision when best alternatives cannot be found. The basic requirements, operation, and procedures of the proposed solution are outlined. A curbside parking has been simulated implementing the suggested double parking operation and important advantages have been identified for drivers, the environment, and the city. Double parking can increase over 50% the parking capacity of a given area. Autonomous car owners would (at least) double their probabilities of finding parking compared to traditional drivers, saving cruising time and emissions. However, significant work and technological advances are still needed in order to make this feasible in the near future.

Capacity Impacts and Optimal Geometry of Automated Cars’ Surface Parking Facilities

“…This is in contrast to the stimulus assumed in (Estepa et al [44]); that study specified the only unique capability of AVs to be that parked vehicles could be blocked in and that a pervasive vehicleto-vehicle communications mechanism would lead to cooperative behavior on the part of one or more AVs to allow the blocked-in vehicle to exit.…”

“…Second, further research is needed to integrate the layout strategies presented in this study with vehicle-toinfrastructure and vehicle-to-vehicle communications of the type recently proposed by Estepa et al [44]. The magnitude and distribution of the combined efficiency gains will be of interest.…”

“…Three prior studies have studied aspects of the spatial efficiency of AV parking (Ferreira et al [42], Timpner et al [43], and Estepa et al [44]). Ferreira et al investigated "stacked" storage of AVs, in which a parked vehicle blocked in by other vehicles would be accessed by the blocking vehicles shunting themselves (without human input).…”

Application of Wireless Accelerometer Mounted on Wheel Rim for Parked Car Monitoring

“…Unauthorized by the owner changes of the car's position may be a result of a parked car being pushed, or of theft [24,25]. Common car theft is realized with breaking into the car and car's ignition system.…”

Protected Turning Movements of Noncooperative Automated Vehicles: Geometrics, Trajectories, and Saturation Flow

“…Within the functional lifetime of much of today's road infrastructure, vehicle automation is expected to impact a range of important aspects of the transportation system, including traffic operations [1][2][3], safety [4], public transportation networks [5], design of arterial streets, limitedaccess facilities, parking facilities [6][7][8], activities performed while traveling [9], and possibly the dominance of the private automobile ownership business model [10,11].…”
