6 Accident Types What accident pattern is focused on? From traffic accident statistics, we will focus on at least three accidents pattern. 1 Rear-end accident 2 Crossing pedestrian-car accident 3 accident causing lane departure 工作物衝突 Traffic accidents in 2013 (N=629,021) 2% その他の車両相互 16% 右折時 8% その他の車両単独 2% 出会い頭 25% 交通事故件数横断中 5% 横断中以外 4% 正面衝突 2% 追突 36% Rear-end accident 36% その他の車両単独路外逸脱 4% 5% 工作物衝突 15% その他の車両相互 6% 右折時 6% 死亡事故件数出会い頭 13% Fatalities (N=4,278) 追突 6% 横断中 25% 横断中以外 10% 正面衝突 10% Crossing pedestrian - car accident 25% 横断中横断中以外 1.6 Fatality rate (%) 死亡事故率 (%) 正面衝突追突出会い頭右折時その他の車両相互工作物衝突路外逸脱その他の車両単独 Accident causing lane departure 6

7 Composition of Models In order to reconstruct 3 types of accidents in the simulation, it is necessary to have at least 4 components. Relationship between each model Environment information Driver Environment Signal Lane etc... response time, brake work etc... Most important but difficult to model Pedestrian walking speed initial position etc... Safety system Vehicle spec etc... 7

Relationship between each model Environment information Driver Environment Signal Lane etc.

8 Driving simulator Driver Models What data is needed for making driver model? In order to develop more accurate simulation, appropriate driver model parameter is necessary(e.g. driver reaction time, brake work etc...). It is essential to acquire the driver response data by experiments. Vehicle simulator Driver response (reaction time, brake work...) 8

necessary(e.g. driver reaction time, brake work etc...).

9 Review of Existing Simulations What simulations are reviewed? Investigation of the existing multi agent simulation tools, in terms of model construction, functional capability, and extendibility. Various multi agent simulation ASSTREET ASSTREET(TOYOTA) SIM for ACAT(HONDA,DRI) ASSESS(NTSEL) MATES(The University of Tokyo) SUMO(DLR:Germany) Prescan(TNO/Tass International) 9

functional capability, and extendibility.

10 Review of Existing Simulations How the prospective simulation is selected? Advantage and disadvantage for each simulation tool are evaluated as simulation requirements. Then, the most prospective simulation is selected. Driver model Requirement for the simulation Algorithm of perception recognition, decision making and control Tool A Tool B Tool C Normal driving situation Accident avoidance situation Driver error Implementation of individual difference Degree of freedom for vehicle dynamics Setup of vehicle specification Setup of automated drive and active safety system Road (road geometry road facilities traffic lane...) Time zone(day-and-night...) Weather (wet-and-dry...) Algorithm of perception recognition, decision making and control Implementation of individual difference The Vehicle simulation model in this project will be developed based on the prospective simulation. Environment model Pedestrian model Total Evaluation 10

11 Requirements of Simulation What function of the simulation tool should have? Requirements of the simulation tool Driver model:perception Recognition, Decision making and Control model Driver error(oversight, Decision making Control miss) etc. Vehicle model:degree of freedom, Automated driving, Active safety system Environment model:road shape, Traffic lane, Facilities and Other conditions (e.g. Weather, Road surface, Day-and-night) Pedestrian model:perception Recognition, Decision making and Action model (Walking speed and walking route) etc... 11

12 Applicability to Other Areas Multi agent simulation tools have applicability to not only estimation of traffic accidents but also other area by adding functions (e.g. traffic jam,environment burden). In this project, extendibility and versatility to other areas are also investigated. Estimation of traffic accidents Estimation of traffic jam + Driver response to Traffic sign ITS system Estimation of environment burden + Gas pedal work Engine output Gas consumption 12

In this project, extendibility and versatility to other areas are also investigated.

13 Summary We aim at developing the simulation which can carry out exactly benefit estimation of active safety system and automated driving system efficiently through this project. In promotion of development and spread for active safety technology and automated driving technology, we are sure that a simulation contributes. Taking advantage of a pioneer's knowledge, it will become a better simulation. 13
