TRAFFIC SEPARATORS ARE LONG DIRECTIONAL ISLANDS, PROVIDED IN FOUR - LANE PAVEMENTS OR WIDE AVENUES TO DEMARCATE THE LINE OF SEPARATION OF THE LANES FOR INCOMING AND OUTGOING TRAFFIC.

Vehicles are confined to paths and when drivers or pedestrians have free choice of routes through large intersections, their actions can not be predicted by others. As such this creates confusion and congestions and often leads to accidents. Keeping in view the vision described above Median strips or traffic separators are long directional islands usually provided in four lane pavements or wide avenues to demarcate the line of separation of the lanes for incoming and outgoing traffic. These take the form of a kerb 60 to 120cm wide with concrete edging and grass turfing in the middle. Pavement strips or lane markers should not be used on the pavement of the rotary roadway or on the entrances and exists. As such sufficient sight distance should be provided where possible and cautionary sign boards (or the standard sign indicating the presence of the rotary) should be put up at proper places required for advising drivers to reduce speeds according to the design speed of the round about. A traffic rotary should be located on a level ground. It may be sited to lie on a plane which is inclined to be horizontal at not more than 1 in 50 and the maximum grade of any approaching road in the vicinity of the rotary should not exceed 1 in 30 . Grades approaching or within a rotary should in no case exceed 1 in 20.White lines -- Traffic lane markings required for the division of the carriage way lanes are made 100 to 125 mm wide (75 mm minimum, 100 mm common) longitudinal strips, and 150 mm wide transverse strips, set out in accordance with the following schedule:- (a) On straight lengths of highway, one metre lines with 4.6 metre gap, 2.7 metre lines with 2.7 metre gap, 1.5 metre lines with 3 metre gaps (b) In town areas with heavy traffic:one metre lines with one metre gaps; one metre lines with 2.7 metre gap. (c) At bends and near junctions: Central continuous line extending 30 metres in each direction beyond the tangent points. Continuous lines are used to prohibit crossing. White and black strips have greater visibility than full white surface. A white line placed 46 cm from the edge of the pavement allows higher night speeds with greater safety. On important roads lay-byes should be provided at intervals to enable vehicles to draw off the road for temporary parking required for break -downs and repairs. Bays should also be provided for bus stops. These should normally be 3 metre wide and at least 30 metre long with 15 metre end tapers on both sides :-- Er Fateh chand Guleria, RTI welfare Association registered number HPCD, 3552 , Bilaspur Himachal Pradesh phone number, 9459334377
