Regarding your articles on the topic of accidents near the A27 Southwick Tunnel (Worting Advertiser, January 15, and Herald, January 16) – here is one possible cause of these accidents.
Some years ago, it was widely publicised that lights flashing with a frequency of around 12 flashes per second could trigger epilepsy-like attacks.
I suggest that an unforunate spacing of tunnel lamps could, at a certain car speed, have a similar effect to flashing lights, causing confusion to the driver.
A rough calculation shows that a spacing of three to four metres between lamps, and a speed of 60 to 70mph, could be hazardous.
If confirmed, removing alternate lamps would eliminate this problem.
