- Paper previously read at the Public Works, Roads and Transport Congress (1935).
- Traffic increasing steadily including during dark hours. Heavy goods traffic
once taken by rail is being carried to an ever greater extent on roadways at night.
This, together with enormous development in omnibus services, has lead to an
"18-hour nation." Number of accidents remains at an appalling figure. A study
of results as are available indicates very conclusively that the accident hazard
at night is several times greater than during daylight. From accident statistics
the following conclusions can be drawn:
- 1. Over 46% of total accidents occur during winter months when
traffic is less heavy than in summer months.
- 2. In winder months 52% of accidents occur during dark hours.
- 3. In summer months 20% of accidents occur during dark hours when
traffic is at a minimum.
- 4. Over the full year over one-third of accidents occur during
- 5. Although the number of "vehicle-miles" in mid-summer months
must be more than twice that of mid-winter with an even greater
relative accident risk the proportion of accidents in dark hours varies
from 12% in summer to 67% in winter.
- 6. Accident rate during dark hours varies from an average of
.31 per hour in mid-summer to .95 in mid-winter.
- 7. In winter months the accident rate at night is double that
- 8. Average number of accidents per hour in the non-built-up areas
in winter is small compared with built-up-areas, but it must be remembered
that the density of traffic is also small, and it will be seen that the
percentage of accidents at night is as high as that for built-up-areas.
Even in mid-summer traffic density in non-built-up areas is still lower
than built-up-areas, but the accident rate per hour during dark hours
is similar to that for built-up areas.
- 9. High accident risk during dark hours in non-built-up areas
in both winter and summer months does not seem to justify the general
assertion of motorists that headlights are bettern than an efficient
- Simpson shows that the accident rate at night is double
the rate in daylight. Simpson comes to the conclusion that
the community pays for efficient public ligting whether it is provided or not,
and that it would be better to pay something more for lighting and considerably
less for accidents. Lennox estimates a (low) figure for the cost of
an accident at £130, and with an estimated reduction in accidents by public lighting
of 10%, then the annual savings to the community would be at least £2.5 million.
- Lighting also a source of civic pride to the local community; and is a deterrent to crime.
- However, local administration and the organisation of local Lighting Authorities prevents the provision
of good public lighting. Smaller authorities may be unable to comply with legal red-tape (parishes) or
be unable to raise enough funds through the rates (urban and rural districts). Uniformity of lighting along
long lengths of roadways will never be achieved. There are 35 Lighting Authorities
in London alone, with around 8,000 around the country. Surveys include the North Circular Road in London
and a detailed and extensive survey of part of the Great North Road (A1).
- A contribution from the Road Fund with a corresponding reduction
in the lighting rates would be a fair suggestion. But the Road Traffic Act, 1934, Section 23 is
unlikely to help as a County Council could be blocked in any scheme by an existing lighting
- 1. The proportion of accidents by night is unduly high.
- 2. They have risen progressively during recent years due to the increase in the
use of roads during dark hours.
- 3. The increase in accident rate at night is due to lack of visibility.
- 4. The pedestrian suffers more heavily than the driver as a result of lack of adequate
- 5. Good visibility obviating use of headlights could be achieved by provision of efficient
- 6. Crime at night would be materially reduced by providing efficient public lighting.
- 7. The cost of efficient public lighting would probably be less than the saving it would
effect on reduction of accidents and crime.
- 8. Public lighting is for the benefit of the community as a whole, and its cost should not
be borne parochially.
- 9. No hope of efficient schemes of uniform lighting can be entertained unless public
lighting is handled by a Central Authority as in the administration of Roads, Transport,
- 10. No smaller unit than a County Borough should be a Lighting Authority. In Rural and
Urban Areas the County Councils should be the administrative Authority.
- 11. As in the construction and maintenance of all Public Properties, Street Lighting
Installations should be under the control of competent Public Lighting Engineers with
a Central Authority, e.g., the Ministry of Transport, to classify roads for lighting purposes,
and to set up standards of lighting for various classes of roads (bearing in mind
traffic density) with a view to obtaining uniformity.
- 12. Public lighting is necessary during 46 per cent. of the year, and is more vital
to-day than ever before.

The Exhibition At Cheltenham p20
Details of the exhibition and a reminder to manufacturers wishing to display their equipment.
Arrangements are also being made for equipment to be installed along various thoroughfares.
The Kingston Bypass p20
Extensive improvements are to be made to the Kingston Bypass and Malden Council has
applied for a grant towards the estimated cost of £4,000 from the M.O.T. to
light its three mile section of the new road.
Progress In Electric Street Lighting p21
Review of the paper The High-Pressure Mercury-Vapour Lamp in Public Lighting. It was noted
that it was the first paper on street lighting read for many years before the IEE. The paper
dealt with the lamp, its auxiliaries, its characteristics (under both starting and running
conditions), the new types of street lighting lanterns developed for it and the new brightness
theory of street lighting. The brightness
theory and the lighting of roadways was covered - also the problem of lighting curves, bends,
intersections and roundabouts.

Osira Street Lighting In Wales p21
Details of new GEC Osira installations in Port Talbort,
Aberavon and Bridgend.
Lighting Scheme At Oxford p21
Information about the first installation of its kind in this country.
Over 80 GEC Oxford lighting lanterns are installed
along Banbury Road, Oxford. They take 500W GLS lamps. The resulting illumination
is greater than that recommended in the Interim Report.
An Interesting Gas Installation At Harrow p22
Several of the main streets of Harrow are being relit by Sugg
London gas lamps. These lamps were adopted after most exhaustive tests.

gas street lighting.
Dual Purpose Lighting p22
Description of the seven REVO Dudley Decorative Cast Iron Standards
and Dudley Lanterns which have been installed around the newly built
Raising And Lowering Traversing Gear p23
The Interim Report of the Deparment Committee on Street Lighting
recommends that lamps should be suspended at 25 ft. for main traffic roads. At this height
lamps cannot be cleaned and maintained economically in position, so a typical raising, lowering
and traversing gear system is described (made by Keith Blackman.)
It is for gas and the supply is disconnected from the lamp as it is lowered for maintenance.
