Electrical Engineering/Electronic road traffic signal boards.


Dear Prof Cleggsan

Do you recommend to have all
Electronic road traffic signal boards
Displayed on the LCD or LED Panel?.

Examples - U turn, Steep curve ahead, School Ahead, No parking etc


There is no technology problem in so doing.  Both LCD and LED lighted and reflective panels are available for such signage.  One problem is maybe difficult to see in bright sunlit days without primary boldly painted surfaces as well so that visibility in all times, day and night, stormy and rainy weather conditions.

Also, in remote areas where traffic on the roadway is light and only few vehicles traverse in given time period the cost of such signage may be prohibited compared with that of conventional one-dimentional signs.

So, it cannot be recommended for "all" traffic sign applications due to cost and roadway authority requirements.
