From: A methodology for improving road safety by novel infrastructural and invehicle technology combinations

Problem	Alternative	Scenario	Technology	Communication type
The LDWSystem is deactivated at the beginning of long construction sites to avoid false alarms.	F. communication with the local infrastructure	Rural, Highway, all drivers all vehicles all traffic conditions, near construction sites	Digital maps/GPS—speed, ldentity and indicator use system, Car-to-car communication via physicaland link-layer based on an UMTS terrestrial radio access network or local area network	Infra → Vehicle
When leaving Road Constructions the driver is reminded to reactivate his LDW-System	F. communication with the local infrastructure			Infra → Vehicle → Vehicle
In-vehicle warning of oncoming vehicles In curves.	G. communication with the local infrastructure	Rural, Highway, all drivers all vehicles all traffic conditions	Digital maps/GPS—speed, ldentity and indicator use system, Car-to-car communication via physical and link-layer based on an UMTS terrestrial radio access network or local area network	Infra → Vehicle
In-vehicle warning of oncoming vehicles In curves.	G. communication with the local infrastructure			Infra → Vehicle → Vehicle
Intelligent edge lines (triggered by vehicle turn indicator) showing a the right way to a vehicle exiting the motorway in case of impaired visibility.	H. Light sensitive sensors (solar cells based) will help the driver to see the edge and centre lines	Rural, all drivers all vehicles all traffic conditions—running light inserted in road surface- all weather esp. reduced visibility	Light sensitive sensors (solar cells based)	Vehicle → Infra
In case of inattention the driver is drifting off the lane	I. CCD^a camera, LDW system to detect unintended lane departure and warn the driver	Rural, Highway, all drivers all vehicles all traffic conditions roads without rumble lines	CCD camera, LDW system: virtual rumble strips	Infra → Vehicle
Road works, tunnels, narrowing road	J. Adaptive LDWA; Sensitivity of Lane Departure warning Assistant is adapted in special conditions,	Rural, Highway, all drivers, all vehicles, special traffic conditions and roads without hard shoulder	Communication with the local infrastructure, LDW	Infra → Vehicle

^aCCD: A charge-coupled device (CCD) is an analog shift register that enables the transportation of analog signals controlled by a clock signal. The camera contains a chip device and no film.
