traffic lights

why not make the top 2 lights on traffic lights
downward pointing triangles
like warning signs

red = stop

red & amber = stop

amber = stop

green = go

this would help those who are colour blind
and may make it more obvious what the sign means
the triangles could be slightly larger than the circle for go
a space could be left at the top for a future addition
a blue light ( see blue wave )


bottle domes

Proposal to help the homeless overseas

The idea is to slightly change the shape of the large PET plastic bottles in which water and fizzy drinks are sold.
By altering the overall shape to that of a truncated cone, that is a slight taper, the bottles can be reused as bricks to build a dome.
With a taper of about 5mm a dome of about 3,000mm height can be constructed. If the bottles are used empty the dome will be very well lit,
but the bottles can be filled with earth, polystyrene, rubbish, or clay.
A bottle can be used as a mould in which to make clay bricks.
A plug of about 30 bottles taped together could be used to form a double-glazed window.
A doorway can be formed with two or three planks of wood making an equilateral triangle.
Once built the dome can be covered with a cement finish even using chicken-wire beforehand to add strength to the structure.

I appreciate that the concept is open to suggestion and improvement.

Blue Wave

Proposal to speed up emergency services through heavy traffic

The initial concept is that
all existing street lights in busy roads of major city centres could have a blue light added. In addition to this, a fourth, blue light could be added to traffic lights at junctions in these zones.

The ‘blue light’ circuit would be arranged in groups corresponding to sections between side streets - similar to the American ‘block’ system.

These groups would be linked into a central
emergency services computer.

Upon receipt of an emergency call, the switchboard operator would tap in the address, and the computer would calculate the optimum route for the vehicles, taking into account any existing road works, traffic accidents, etc. All blue lights along the route selected by the computer would immediately be activated - possibly in conjunction with an audible warning. All traffic and pedestrians along the route would then have plenty of prior warning to clear the roads and stay clear ensuring swifter access to an emergency. This could even be made a legal requirement. Traffic lights on the periphery of this zone could all be set to prevent ingress but allow egress from the zone helping to thin out the traffic.

I appreciate that the concept is open to suggestion and improvement, for example, in roads without central reservations, two blue lines, about ten feet (3 meters) apart, could be painted along the road. Remember, we’re talking about busy streets in some town centres, not every village in the country. Every effort should be made to clear this area when the blue lights start to flash.

The public would have to be taught to use the system. In light of the increased, and increasing, density of traffic, ease of access along these busy routes by emergency vehicles is fast becoming a necessity.
