1 De How Rij-Assistent to organize a FOT fleet Experiences from The Netherlands Tom Alkim How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

2 Overview Recent FOTs in The Netherlands The Assisted Driver Objectives Methodology How to organize a fleet AOS How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

3 Field Operational Tests in NL Dutch Field Operational Tests on intelligent vehicles have shown over the last couple of years: Demo 98: showcase up to autonomous driving (1998) Enthusiasm about technology possibilities ISA FOT: set external speed assistant experiment Tilburg (2001) Good acceptance, indications for better safety LDWA FOT: trucks ( ) High acceptance, expect less accidents and less traffic jams Chauffeur Assistant: laboratory truck FOT (2004) No negative traffic impacts, workload decreases How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

4 Recent Field Operational Tests in NL Belonitor: awarding good behaviour (2005) Positive road users, expect less accidents and less traffic jams, more efficient fuel use Roadwise: in car speed info & entertainment (2005) Positive expectations, better use of the road capacity The Assisted Driver: passenger cars with ACC + LDW ( ) Positive results How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

5 Current Field Operational Test in NL Accident Prevention Systems for lorries (2008/2009) How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

6 The Assisted Driver Goal: Provide a peek into the future of ADA systems and evaluate the impact on traffic flow in terms of safety, throughput and environment as well as driver behavior and acceptance. Increase awareness of ADA systems How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

7 The Assisted Driver - movie How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

8 Elements of the Field Operational Test Virtual Reality Demo day (24 May 2005) VANpool Full Traffic Clinic Test drives How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

9 Elements Why these elements in this order? First provide a peek into the future of ADAs and increase awareness: Demo day Choice systems: longitudinal + lateral, because: Head-tail accidents (40-45%), single accidents (20%), aside accidents (12%); top three of accidents on Dutch highways First HMW/LDW (warning) Than LDW/ACC (warning / support) Finally ACC/LKS (support) How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

10 Demo day More than 200 visitors, 30 cars with ADAs Real life experience on public roads and test track How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

11 VANpool Existing initiative, LDW and HMW installed by RWS Evaluating LDW and HMW, duration 5 months Participants change driving behavior, prefer LDW How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

12 Lane Departure Warning (Mobileye) How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

13 Headway Monitoring and Warning Target detected Warning volume settings System status (maintenance or no visibility) Headway (in seconds) Driving style preferences How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

14 Headway Monitoring and Warning Dangerous driving Driving too close Safe driving How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

15 Full Traffic 20 vehicles (VW Passat) equipped with ACC / LDW One month reference, four months experience Objective data Estimate impact on traffic flow safety throughput environment Behaviour and acceptance How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

16 Lane Departure Warning How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

17 Lane Departure Warning How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

18 ACC How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

19 ACC How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

20 ACC Headway selection ( etc) Select current speed Tap upwards, speed increases by 10 km/h Tap downwards, speed decreases by 10 km/h Braking: ACC switches off Accelerator: ACC temporarily deactivated, not switched off Range: km/h How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

21 Clinic with ACC and Lane Keeping Assist (LKA) 3 days of driving in Lexus GS with ACC / LKA Put results of Full Traffic (ACC / LDW) in perspective Participants prefer LKA over LDW How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

22 Clinic - LKA How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

23 Test drives Policy makers Stakeholders Colleagues ITS London Mayor of Beijing How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

24 Roads to the Future TV - Final Event Results presented in studio DVD (in Dutch) available Results published in book How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

25 Objectives (Full Traffic) Perform an objective analysis of the effect of driving with ACC and LDW (in mixed traffic on Dutch roads) on individual driving behavior and ultimately the impact on traffic flow in terms of safety, throughput and environment. Evaluate driver behavior and acceptance by means of questionaires and focus groups How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

26 Methodology Full Traffic Subjective part: Behavior and acceptance by TNS-Nipo Objective part: Analysis of data from dataloggers by Technical University of Delft How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

27 Methodology Full Traffic - Traffic impact 0. data - verzameling 1. data - analyse 0. Dataverzameling = data collection 1. Data-analyse = data analysis 2. Onderzoek rijgedrag = research driver behavior 3. Effecten studie = research effects 4. Expert workshop 5. Synthese = synthesis 2. onderzoek rijgedrag 4. expert - workshop 3. effectenstudie 5. synthese How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

28 Data loggers GPS TRAVLA GPRS ARS ACC LDW Eventbutton Data is sent as frequently as possible Some data is only stored on car PC How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

29 Conclusions - behavior and acceptance Participants prefer active assistance over passive assistance (warnings): ACC and LKS over HMW and LDW Participants prefer system which gives least number of warnings: LDW over HMW Participants don t think that the combination of ACC and LKS is too much which was expected beforehand Combination of ACC and LDW seems beneficial for vigilance, where ACC sometimes leads drivers to perform secondary tasks, LDW keeps them alert How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

30 How to organize a fleet? Difference between theory and practice... Rationale for FOT Plan Proces Fleet Maintenance How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

31 Rationale for FOT Literature / theory Model study Simulator study FOT Deployment Purpose Knowledge about: driver behaviour (subjective and objective) Technical performance (objective) Increase awareness Stimulation (cooperation, introduction, deployment) How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

32 Plan for FOT (Assisted Driver) 100 vehicles with ACC (full range) and LKS control group without ADAs but with Dataloggers duration one year distribution participants (gender, type, experience, etc.) participants: drive similar routes every day (% highway, rural, city) under comparable conditions (% weather, traffic) stay in the Netherlands Dataloggers transmit data wireless camera s on-board How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

33 Process (Assisted Driver) contacts with OEMs, importers, fleet owners direct contact or publication relation public parties / private parties innovative contract with third party as broker participants: approach customers via showroom approach customers via fleet owner make it interesting for them How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

34 Fleet (Assisted Driver) 100 vehicles with ACC (full range) and LKS 19 vehicles with ACC and LDW (aftermarket) control group without ADAs but with dataloggers no control group duration one year duration five months Dataloggers transmit data wireless camera s on-board no camera s How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

35 Fleet (Assisted Driver) distribution participants (gender, type, experience, etc.) 17 males, 2 females, all but one lease-drivers, most of them motivated and interested in new applications drive similar routes every day (% highway, rural, city) no influence, they drove everywhere under comparable conditions (% weather, traffic) quite some variance stay in the Netherlands some of them went on holidays, with and without car How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

36 Maintenance (Assisted Driver) one contactperson / phone number anticipate some malfunctioning (car, ADAs or datalogger) how long before car is fixed? Usually out of your hands how long before ADAs or datalogger is fixed? You can control this removing systems after FOT How to organize a fleet - FOTnet seminar 2, Brussels 28 oktober

37 Lessons learned be ambitious! You will not get want you want... be creative define a go / no go moment (bottom line) communicate well one projectmanager, full-time! one contactperson for fleet management make arrangements, if possible contracts...
