![]() Most importantly, in the authors' opinion, was the fact that the simulator T-scores of the handicapped subjects correlated very well with their driving performance T-scores. Simulator T-scores for the handicapped subjects reflected large variations in their tracking abilities due to differences in their functional capabilities. The T-score transformed the performance of these subjects into scores having as a common reference the performances of the able-bodied subjects. In order to compare the simulator performances of the handicapped subjects with their driving performances, their performance scores were all converted to T-scores. Nine severely disabled subjects were then tested in the simulator and in driving tests in the van. Simulator RMS tracking error and the number of traffic cones knocked down were the respective performance measures for these tests. Twenty-five able-bodied subjects were tested on the simulator and 13 of them were then given driving tests in a Scott van. The simulator presents a two-dimensional tracking task to be carried out using the driving controls of the Scott van, which is a uni-lever servo-controlled vehicle designed for the severely impaired. The result of this two-phase assessment ensures that the driver is able to fulfill the minimum driving requirements needed for obtaining the driving license.Ī simple simulator for evaluating the physical capabilities of severely handicapped prospective drivers was developed and evaluated. The second phase includes a series of practical driving tests on a closed circuit. The first phase of the assessment requires the use of a new experimental tool, consisting of a simulator allowing the safely measurement of all the parameters needed to determine the residual capacities for driving in a Joystick adapted vehicle. The aim of this new assessment was based on performing a series of practical tests divided into two phases. The project was conceived for evaluating severely disabled drivers suffering from illness who impaired them to drive a motor vehicle due to sever disability in Spain. ![]() ![]() This paper present a new assessment procedure developed in the project Joystick for Driving (J4D), promoted and funded by ONCE Foundation with the technical collaboration of the University Polytechnic of Valencia (Spain). Driving motor vehicles by People with Reduced Mobility (PMR) has always been regarded by administrations as an anomaly that from the technical and legal environment has generated a number of restrictive barriers that especially affects the legislation related to the process for obtaining the driving license. ![]()
