Teaching learner drivers with disabilities : An operation manual for driving instructors
- 2000
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The present manual is one of the outcomes of an EU-project with the title ODIGO. It was carried out within the Horizon initiative. As part of the ODIGO/HORIZON project Körkort Handikapp, Lernia in Kävlinge (formerly AmuGruppen, Kävlinge) in Sweden were requested to produce an operation manual for driving instructors, to be used in driver education for persons with special needs (PSN).The present manual is aiming at providing knowledge about PSN and to support driving instructors that educate PSN. In the introduction of the manual, the require-ments demanded of a driving school facility and some general aspects of teaching are considered. In the following driver education exercises are presented. In those, references to Appendix 1 are inserted, in which specific aspects of the driver education with respect to PSN are discussed. This appendix also includes an introduction to the area of education and PSN. In addition, a section called “Disabilities and vehicle adaptation” is enclosed, in order to provide an orientation within the field of PSN and vehicle adaptation. In the last section a suggestion for a lay out of logbook sheets for driver education is enclosed.

Energy savings in systems of coordinated traffic signals, especially with Automatic Updating (AUT)
- 2000
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Fuel consumption on passing through coordinated signalised junctions could be reduced by at least 12 % by the use of AUT. AUT is a most cost effective method based on existing equipment. AUT demands the facility to send traffic data from controllers to a central PC and to send updated time plan data back to the controllers. It has been estimated that in the test area the average cost reduction is SEK 1 000 000 per year and junction. The maximum investment cost for an AUT installation is SEK 100 000/junction. AUT makes it possible for the number of time plans per day to be increased, which in the test area could increase the fuel saving to 15%. Optimised signal control will reduce delay in the signal system. AUT does not directly deal with redistribution of traffic inside and outside the signal system due to the change in delay. By means of a traffic assignment model this effect has been estimated to be of minor importance in the test area and in the outside area. AUT includes the TRANSYT programme. A validation study from before has shown an overestimation of stops. In order to make a control of the validation result a simulation model based on statistical theory was developed for external link simulations. Simulated stops by TRANSYT were significantly higher than simulated by the statistical model. Since the deviation was systematic it was possible to include an automatic ad-justment of estimated effects but not in the optimisation process. This may be expected to result in a lack of effectiveness even if output data could be made representative.
