4. Road types Motorway/highway Urban Suburban Rural Weather Conditions Fog Rain Wind Snow Road segment Tunnel Bridge Curved road Straight road Intersection/junction Roundabout Pedestrian crossing Signalled Unsignalled Diurnal cycle Night Day Current Status of SP1 • Initial approach taken was to define scenario titles and attributes, however this did not provide a basis/justification for selection Driving Scenario Attributes

5. Vulnerable road user warning Pedestrian in the road Motorcycle overtaking Pedestrian on the Zebra crossing Pedestrian using pelican crossing Hazard warning Obstacle detected in the road Vehicle travelling in the wrong direction Emergency breaking Driver braking erratically Vehicle being driven erratically Emergency vehicle approaching Accident warning Stolen vehicle warning Environmental hazards (Fire/smoke, pollution) Vehicle has run a red light Road works/lane restrictions Dangerous goods being transported Train approaching road crossing Heavy goods vehicle Current Status of SP1:Initial Scenarios

6. Driving support Vehicle exceeding advisory speed limit Traffic lights about to change Lane departure support Road works Uneven road surface Lane closures Lane departure support Cooperative driving Lane merge Lane change Traffic beyond range of ADAS sensors slowing down Current Status of SP1: Initial Scenarios

7. Current Status of SP1 • New approach now being followed to select and describe “basic scenarios” • Previous approach gave no basis or justification for the focus of SP1 scenarios • Preliminary selection of scenario titles made • Preliminary list of scenario titles described using basic scenario template

8. SP1 Scenario Selection Process (1) • In order to provide a basis for the selection of commonly agreed ‘priority scenarios’ between partners, the following approach has been taken: • Scenario groupings defined relating to generic affects on a normal (non-risky) driving situation that can trigger a scenario. • Normal driving (“non-risky) • Road surface condition change (incl. road friction) • Lane traffic condition change (incl. obstacle) • Weather visibility change • Approaching intersection • Significant road geometry change • Lane change • Abnormal driver behaviour

9. SP1 Scenario Selection Process (2) • Each partner contributing to the scenario task defined scenario titles according to the groupings in step 1. • Partner contributions collated and overlapping scenarios merged • Remaining scenario titles rated according to their priority by each partner: • Top priority = 1 • SAFESPOT relevant = 2 • Nice to have = 3 • More information needed = 4 • Reject = 5

10. SP1 Scenario Selection Process (3) • Assessment of partner ratings carried out • Due to rating anomalies the following selection criteria was applied to identify scenarios according to level of priority: • Priority: all partners agree • Priority L1: Mixed rating of 1 and 2 and Mode = 1 • Priority L2: Mixed rating of 1 and 2 and Mode = 2 • Priority L3: Mixed rating 1, 2, 3 and MODE = 1 • Other criteria: More info & reject, unclassified

11. SP1 Scenario Selection Process (4) • Preliminary priority scenario list • Obstacle (VRU, load, slow veh, jam) in ego lane, Priority L1 • Ego turn, approaching obstacle (VRU, load, slow veh, jam) or crossing its path, Priority L1 oncoming vehicle in wrong direction in ego lane, Priority L1 • Ego approaching spot with ice in ego lane, Priority • Ego vehicle runs a red light or stop sign, Priority L1 • Ego vehicle approaches vehicle fire/smoke section (inside a tunnel, on motorway) , Priority L1 , • Ego vehicle approaching road works - restricted lane usage, Priority L2 • Emergency vehicle approaching - blue corridor required (cooperative message exchange between vehicles), Priority L1 • Ego vehicle - Lane departure (incl. off road), Priority L1 • PTW falling on roadway, Priority L3 • ego (PTW) overtaking OV while OV making a turn, Priority L1 • Ego-vehicle starts braking very hard while other vehicle (PTW) is following , Priority L1 • overtaking ego on collision path with oncoming vehicle, Priority L1 • Ego vehicle carrying dangerous goods • Ego vehicle meets dangerous goods vehicle

12. SP1 Scenario Selection Process • Basic scenario template • The Fields defined within the template aim to capture the selection of attributes from the “attribute scenario diagram” in order to describe a ‘basic’ description of the scenario. • Flowchart created to lead the author of the basic scenario through the process of completing the template (see handout or CBWA)
