Transportation, Highway Engineering and Ports & Harbors (Chapter 1.226-1.250) GROUP 5_3J

1. A type of line that is used where crossing of the line is either discouraged or prohibited. It is generally used to replace or supplement a broken line where required eg. barrier lines, and center lines. It may be either yellow or white depending whether or not crossing the line is legally prohibited.

Solid Unbroken Lines

2. Means any traffic control device marked on the surface of the carriageway used to regulate traffic or to warn or guide road users.

Road Markers

3. Shall mean any public thoroughfare, public boulevard, and avenue, but shall not Include roadway upon grounds owned by private persons, colleges, universities, or other similar institutions.

Highway

4. Means any level crossroad, junction, including open areas formed by such crossroad.

Intersection

Brown

6. Max. speed limit for rural roads

60 kph

7. It is used to separate opposite traffic movements of an undivided roadway and is generally placed centrally on all roads and bridges 6.0 m or more in width. Under some circumstances this line may be placed off-center (e.g., where an extra uphill traffic lane is provided or parking on one side of the road only)

Center Line

8. A center line may be marked on an urban or rural road if one or more of the following conditions are met:

I. Two lane road (greater than 6 m in width) carrying an Annual Average Daily Traffic (ADT) in excess of 1000 vehicles

II. Two lane road (less than 6 m but more than 5 m in width) carrying an ADT in excess of 300 vehicles

III. Winding roads with widths of 5 m or more.

IV. Two lane roads greater than 10 m. in width

I, II and III only

9. If the bridge is 5 m. or more between curves, center line marks shall be_______.

continued across the bridge

10. if the bridge is less than 5 m. between curbs, center line marks shall be________.

discontinued 30 m. from the bridge abutment

11. The center line on a two-lane two-way rural road or any other road where the 85 percentile speed (or speed limit) is greater than 60 kph, shall be a broken line, with a minimum width of 150 mm and 3 m. long with gaps of______ spacing.

9 m

12. A line used to separate adjacent lanes of traffic moving in the same direction.

Lane Line

13. Lane lines on roads with 85th percentile speed (or speed limit) of 60 kph or less shall have a minimum width of 150 mm and 3 m. long with________ gaps.

6 m

14. Lane lines on roads with 85 percentile speed for speed limit) in excess of 60 kph shall be 150 mm wide, 3 m. long and________gaps.

9 m

15. Lane fines must not be continued on the following cases:

I. Across signalized intersections. However, tane lines of low priority road must be discontinued at the Intersection.

II. Across silde street entrances unless the streett is one-way street (going in only)

III. Past the start of the taper at which a multi-lane road narrows down

IV. At approaches to widened or signalized intersection

V. On divided roads

I, II, and III only

16. As a guide, lane lines should be used in the following cases:

I. Where the road is wide enough for two or more lanes of traffic in one direction with a two way annual average dally traffic (AADT) of 8000 or more (depending on whether parking is permitted)

II. At approaches to widened signalized intersection

III. On divided roads

IV. Across signalized intersections

I, II, and III only

17. Lane lines which indicates that overtaking from both directions of the road are prohibited. However, cross movements are permitted. Vehicles must always keep to the right of the double yellow lines.

Single Unbroken Yellow Line

18. Barrier lines may consist of either:

I. Two unbroken yellow lines

II. Single unbroken yellow line

III. Single yellow line with a broken white line

IV. Single white line with a broken yellow line

I, II and III only

19. Lane lines which indicates that overtaking from both directions of the road and all crossing movements are prohibited.

Double Unbroken Yellow Line

20. The following are the cases where barrier lines should be used:

I. As center lines on approaches to signalized intersections

II. As center lines of multi-lane roads where overtaking must be prohibited, because of sign restrictions

III. No-Passing zones where there is a restricted sight distance due to horizontal or vertical curves, or both

IV. As center lines on approaches to railway crossings

All of the above

21. Markings to 'No-Passing Zones are applied to:

I. Vertical and horizontal curves on a two-lane sealed road

II. Barrier lines shall not be marked unless the sight distance available falls below the appropriate minimum sight distance for at least the length allowed

Ill. If the length of road, with sight distance below the minimum sight distance, is less than the minimum length of barrier line allowed.

IV. Where the distance between the end of one barrier line and the beginning of the next barrier line restricting traveling in the same direction is less than that allowed for roads and highways

All of the above

22. Lines used to delineate the edge of the traveled way to distinguish it from the shoulder area. It should be a solid white line between 100 mm and 200 mm wide.

Edge Lines

23. The purpose of installing edge lines is generally based on the following:

I. to discourage travel on road shoulders

II. to make driving safer and more assured, particularly at night and during inclement weather by providing a continuous guide for the driver

III. to act as a guide past objects, which are close to the edge of pavement and which constitute a hazard

IV. to prevent parking at or near intersections

All of the above

24. The recommended width of edge lines for urban road with outer lane width of 3.5 m.

100 mm

25. The recommended width of edge lines for rural roads with outer lane width of 3.5 m.

100 mm
