Q

Classifications of signs

A

*Regulatory Signs
* Warning Signs
* Guide Signs or Informative Sign
* Signs for Expressways
* Signs for Special Purposes
* Hazard Markers

25
Q

To be effective, the road sign should meet the five basic
requirements:

A
  • Fulfill a need
  • Command attention
  • Convey a clear, simple message
  • Command respect; and
  • Give adequate time for proper response
26
Q

It should be noted that when all sign rules have been followed, some visual judgment must be exercised in adjusting sign elements. The following general rules are to be applied when designing the sign face:

A
  • Cramping of legend is to be avoided;
  • Avoid large areas of blank panel, particularly blank areas
    not symmetrically disposed across the panel;
  • If there are two list of legends side by side (e.g., as on
    Reassurance Signs) it is necessary to left justify the left list
    and right justify the right list; and,
  • Elements such as arrows and symbols may sometimes
    have to be larger than the principal legend would normally
    require. For example, an arrow relates to several lines of
    legends on a direction sign
27
Q

Classification of Regulatory Signs

A

*Priority Signs
* Direction Signs
* Prohibitive or Restrictive Signs
* Speed Signs
* Parking Signs
* Miscellaneous Signs

    roads
  • Size D for Expressways
29
Q

32
Q

One-Way hazard markers indicate to the approaching driver the direction to be followed if the marker appears in the driving path. They may point to the left or right as appropriate and are used as follows:

A
  • To delineate an abrupt narrowing of pavement, for
    example, at a lane drop;
  • At exposed ends of raised median islands where traffic is
    required to pass to one side;
  • On central island of a roundabout facing entering traffic;
    and
  • To delineate the curve approach just prior to entering an
    intersection.
33
Q

Pavement markings have definite limitations:

A
  • They are subject to traffic wear and require proper maintenance;
  • They may not be clearly visible if the road is wet or dusty;
  • They may be obscured by traffic;
  • Their effect on skid resistance requires careful choice of
    materials; and
  • They cannot be applied on unsealed roads.

  • Grade separated intersections for extremely high flows
    and other intersecting expressways;
  • Number of intersections to be minimized and
  • Where necessary or for emergency purposes,
    parking/stopping to be provided clear of the main
    carriageway.

  • Suitable at-grade channelized intersections for minor flows and other elements
  • No roadside vendors
37
Q

Color of Pavement Markings
The color of pavement markings shall be white except for
the alternative uses of yellow as specified below:

A
  • Double yellow no-passing lines;
  • Unbroken portion of no-passing lines;
  • Curb markings for prohibition of parking;
  • On islands in line of traffic;
  • Bus and PUJ lanes; and,
  • Keep Intersection Open markings
    Red shall be used in:
  • No Loading/Unloading Zone; and
  • Fire lane zone
38
Q

Design Speed
The choice of an appropriate design speed for a road project
is important to ensure a safe design.
When choosing a design speed, the following factors need to
be considered:

A
  • Function of the road
  • Anticipated operating speed
  • Anticipated speed limit
39
Q

Warrants for Marking Center Lines
A center line may be marked on an urban or rural road if
one or more of the following conditions are met:

A
  • Two lane road (greater than 6 m in width) carrying an
    Annual Average Daily Traffic (ADT) in excess of 1000
    vehicles;
  • Two lane road (less than 6 m but more than 5 m in width)
    carrying an ADT in excess of 300 vehicles; and
  • Winding roads with widths of 5 m or more.
40
Q

Barrier lines may consist of either:

A
  • Two unbroken yellow lines;
  • Single unbroken yellow line; or,
  • Single yellow line with a broken white line
41
Q

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

A
  • As center lines on approaches to signalized intersections;
  • As center lines of multi-lane roads where overtaking must
    be prohibited, because of sign restrictions;
  • ‘No-Passing’ zones where there is a restricted sight
    distance due to horizontal or vertical curves, or both; and
  • As center lines on approaches to railway crossings
42
Q

Warrants for Use
Because of the high cost of installation and maintenance,
use of raised pavement markers may be considered only in
the following condition:

A
  • In hilly areas where fog and rain are frequently the causes
    of traffic accidents; and
  • In winding roads and accident prone areas.
43
Q

The provision of safety sight distance depends on the characteristics of the driver such as:

A
  • Alertness of driver
  • Recognition of the hazard
  • Actions available to the driver – to stop or to change
    direction
44
Q

The provision of safety sight distance depends on the
characteristics of the vehicle such as:

A
  • Type of vehicle – car or truck
  • Friction between the tire and the road
  • Eye height of the driver
  • Speed of vehicles
45
Q

The provision of safety sight distance depends on the
characteristics of the road environment such as:

A
  • Road geometry – grade and curvature sight limitations
  • Road surface – sealed or unsealed, smooth or rough
  • Road illumination at night
46
Q

Each type of sight distance consists of three elements:

A
  • Driver Eye Height
  • Object Height
  • Sight Distance
47
Q

Two components in stopping sight distance:

A
  • Reaction distance – the distance traveled while the driver
    perceives a hazard, decides to take action, then acts by starting to apply the brakes to start slowing down; and
  • Braking distance – the distance required for the vehicle to
    slow down and stop
48
Q

Four different criteria used for the establishment of sag
vertical curves:

A
  • Headlight sight distance
  • Passenger comfort
  • Drainage control
  • General appearance
49
Q

PPA has used MLLW as the datum line for design of port
facilities in accordance with charts. But there are many
ports of which low tide go down very often below MLLW.

For instance: (Port Cebu)
According to the tide table (1991) of NAMRIA, the
frequency of tide below MLLW is 213 times/year and the
maximum amount of the value is -0.51 m. Under this
condition it is dangerous for ships to utilize the port.

Q

Shoulder paving is a valuable method of providing:

A
  • Integrity of the pavement
  • Width to place edgeline pavement markings
  • Additional safety to prevent vehicles skidding or drivers
    losing control in gravel.
  • Low maintenance costs compared with unpaved shoulders
51
Q

Element of Berthing Facility:

A
  • Planned Water Depth
  • Design Water Depth
  • Coping/Crown Elevation

53
Q

Types of intersections that generally exist on the road network are:

A
  • Unflared and unchannelized intersections (without
    widening or traffic islands)
  • Flared and unchannelized intersections (with widening
    but without traffic islands) and
  • Channelized intersections (traffic islands to guide traffic)
54
Q

Principles of good design to reduce the likelihood of traffic
accidents include:

A
  • Minimize the speed of vehicles at potential collision points
    *Separate movements and points of conflict by
    channelization, or in some situations, prohibit certain
    movements (and provide for them at other
    intersections along the route)
  • Control movements to reduce the possibility of conflict
    and
  • Clearly define vehicle paths by use of pavement markings
