Motorbike detection

Situation on urban motorways (Paris)

Motorbike detection

Human factors

Motorbike = freedom

Motorbike = saves commuting time

Motorbike = no need to find parking location

Many PTW users are not ‘bikers’

Mixed traffic: experienced users share the road with new comers or foreigners

Driving rules are transgressed

Implicit & unwritten driving rules are widely used

Motorbike detection by Radar

Test Drive Evaluation

Used Sensor: Valeo MBH radars, 24GHz narrow band

City traffic in Paris ( motorbikes are often shadowed by following cars)

113 motorbikes used for analysis

act. Truck 94.51% 5.28% 0.21%

act. Car 2.89% 92.79% 4.32%

act. Motorbike 0% 1.91% 98.09%

Fast moving targets on German motorway

Confusion matrix

Performance of the algorithm is compared with the manual classification to generate the following confusion matrix

Compared was a 3 hours long test drive on German motorways where the probability of finding a motorbike is low

Motorbike detection by camera

Learning algorithm for day time

Lighting identification at night time

Issue with classification

Issue with distance and speed estimation

Issue with salience now that Daytime running lamps are mandatory on cars and motorbikes

Motorbike detection by C2X communication

Requires On-Board Unit and antenna on Motorbikes, and accurate GPS

WiFi 802.11p is recommended, Visible Light Communication may be investigated

Standard data transfer protocols: Communication Awareness Messages (ETSI TS 102637-2)

=> SafeVRU H2020-2014 proposal

Motorbike detection on urban motorways

Conclusions

Small business volumes for EU motorbike sales => adaptation of standard solutions from vehicle detection

Sensor fusion is necessary on vehicles for PTW detection

New ADAS functions on vehicles will integrate the base equipments:

Blind spot and Lane Change Assist Radars

Sensor cocoon for Overtaking Maneuvers and Intersection Assist

Cameras for e-Mirrors

C2X communication
