Introduction Purpose of Road Safety 1. Reduce no. of accidents 2. Safer journey 3. Increase quality of transit system 4. Maintain regular traffic flow 4. Rumble Strips Other names:- Sleeper lines or Alert strips Rumble strips are grooved patterns rolled or milled into the pavement perpendicular to the direction of Travel. 5. Types of Rumble Strips 1. Shoulder Rumble Strips  Placed on highway shoulders along the edge of the travel lane, to prevent single vehicle run-off-the-road crashes. 6. Types of Rumble Strips 2. Centerline Rumble Strips  Placed on or near the center line.  To prevent head-on crashes and opposite direction sideswipe crashes.  Prevent some crashes, when a driver veers across the center line. 7. Advantages of Rumble strips  Alert drivers upon drifting or deviation.  The reflective paint helps to increase visibility.  Reduce the number of crashes. 8. Design of Road-Side  Requirements:- 1. Provide Shoulder & Edge strip 2. Avoid sharper turns 3. Provide Emergency zones/lanes 9. Design of Road-Side  Requirements:- 4. Free from Ditches 5. Proper Screeding 10. Design of Road-Side  Requirements:- Super elevation = h = (Bv^2)/gR 6. Super elevation is not be too steep 11. Junctions  A road junctions is a location where multiple roads intersect, allowing vehicular traffic to change from one road to another. 12. Junctions  A road junction has to fulfill following requirement :-  Visible  Oversee-able  Comprehensible  Completeness 13. Traffic Signs  Traffic signs or road signs are signs erected at the side or above of the roads to give instructions or provide information to road users.  Traffic signs generally :-  Control the flow of traffic.  Guide to destination.  Informs roadway services. 14. Traffic Signs  Traffic signs are intentionally color coded to assist the operator.  In traffic signs, fluorencent material is used. Red Green Yellow Stop Direction Warning 15.

3. Introduction
Purpose of Road Safety
1. Reduce no. of accidents 2. Safer journey
3. Increase quality of transit system 4. Maintain regular traffic flow

4. Rumble Strips
Other names:- Sleeper lines or Alert strips
Rumble strips are grooved patterns rolled or milled
into the pavement perpendicular to the direction of
Travel.

5. Types of Rumble Strips
1. Shoulder Rumble Strips
 Placed on highway shoulders along the edge of the
travel lane, to prevent single vehicle run-off-the-road
crashes.

6. Types of Rumble Strips
2. Centerline Rumble Strips
 Placed on or near the center line.
 To prevent head-on crashes and opposite direction
sideswipe crashes.
 Prevent some crashes, when a driver veers across
the center line.

7. Advantages of Rumble
strips
 Alert drivers upon drifting or deviation.
 The reflective paint helps to increase visibility.
 Reduce the number of crashes.

8. Design of Road-Side
 Requirements:-
1. Provide Shoulder & Edge strip
2. Avoid sharper turns
3. Provide Emergency
zones/lanes

9. Design of Road-Side
 Requirements:-
4. Free from Ditches
5. Proper Screeding

10. Design of Road-Side
 Requirements:-
Super elevation = h = (Bv^2)/gR
6. Super elevation is not be too steep

11. Junctions
 A road junctions is a location where multiple roads
intersect, allowing vehicular traffic to change from
one road to another.

12. Junctions
 A road junction has to fulfill following
requirement :-
 Visible
 Oversee-able
 Comprehensible
 Completeness

13. Traffic Signs
 Traffic signs or road signs are signs erected at the
side or above of the roads to give instructions or
provide information to road users.
 Traffic signs generally :-
 Control the flow of traffic.
 Guide to destination.
 Informs roadway services.

14. Traffic Signs
 Traffic signs are intentionally color coded to assist
the operator.
 In traffic signs, fluorencent material is used.

16. Types of Signs Boards
1) Stop & Yield Sign Boards
A STOP sign is a traffic sign to notify drivers to
completely halt while YIELD means to slow down
to at a point.

17. Types of Signs Boards
2) Warning Signs :-
Alert to hazards or changing in conditions such as
changes in road layout, proximity to a school zone,
Sharp turns etc.

18. Types of Signs Boards
3) Guide Signs :-
Indicates route markers, distance-and-destination
signs, and informational signs.

19. Types of Signs Boards
4) Construction & Maintenance Road
Work Warning :-
 The work areas are protected from traffic by
orange (or yellow) warning signs during the
construction or repairing works.
 Help to guide pedestrians and vehicle traffic
safely through a work zone and past any hazards
