of these powers. Detailed recommendations are made covering the design and siting of street name plates and the allocation and display of street numbers. (Paragraph 144.)
(35) White Lines.—White lines should be used:
(a) As “Stop” lines at road junctions.
(b) As guide lines at junctions.
(c) As guide lines at horizontal and vertical curves, and on approaches to central obstructions in the carriageway.
(d) To define traffic lanes on open lengths of road.
(e) To define the boundary of the main carriageway at entrances to side roads, etc. (Paragraph 145.)
“Stop” lines at pedestrian crossings should be separate from the lines of studs defining the crossings. (Paragraph 146.)
The marking of three traffic lanes on carriageways of approximately 30 ft. width should be discontinued in favour of a central line. (Paragraph 150.)
Intermittent centre line markings on two-way carriageways should consist of a 9 ft. mark and a 9 ft. gap. (Paragraph 150.)
Traffic markings on the carriageway should be white. (Paragraphs 153 and 165.)
(36) Other Traffic Signs on the Carriageway.—Carriageway markings indicating the position of bus stops should be permitted. (Paragraph 160.)
The wartime practice of marking kerbs and upstanding objects near the carriageway with white paint should be continued. (Paragraph 161.)
(37) Traffic Light Signals—No major alterations are suggested in the existing traffic light signal systems, but certain experiments are recommended. (Paragraph 167.)
(38) Signal Sequence.—As an experiment, a selected group of signals should be operated with the “Red with Amber” signal omitted, to determine whether increased safety, without increased delay to traffic, can thereby be obtained. (Paragraph 168.)
(39) Pedestrians and Light Signals—Methods for making provision for pedestrian traffic at signal installations are indicated, and the experimental provision of a series of pedestrian signals controlling vehicular traffic on a flexible progressive system is recommended. (Paragraph 173)
(40) Review of Isolated Fixed-Time Installations—Isolated fixed-time installations should be reviewed and converted to a vehicle-actuated system where this is likely to result in the more efficient control of traffic. (Paragraph 175.)
(41) Marking of Pedestrian Crossing Places.
(a) The orange globe on the beacon should be illuminated internally during the hours of darkness. (Paragraph 180.)
(b) Studs should be white.
(c) The spacing of the studs should be increased to 28 in. centre to centre.
(d) Studs fitted with reflecting lenses should not be used on pedestrian crossings.
(e) No form of carriageway marking other than the authorised studs should be permitted at pedestrian crossings (Paragraph 181.)
