Philippines Traffic Management Agencies Quiz

Traffic Management Overview

• This module details government efforts for systematic traffic management
• It explains various roles of government and non-government agencies responsible for managing traffic
• The course is divided into three lessons: Fundamentals of Traffic Management, The Pillars of Traffic, and Traffic Safety Education

Fundamentals of Traffic Management

• No specific details are provided

Arterial Highway/Roads

• Arterial highways are high-capacity urban roads
• They connect lower capacity roads (collector roads) to expressways or freeways
• Examples include 23rd Avenue and Colfax Avenue

Articulated Vehicle

• This term refers to a combination of vehicles
• It comprises a motor vehicle and a semi-trailer coupled to the motor vehicle
• The definition is from UN-VCRT (1968)

Built-Up Area

• An area with entrances and exits, as defined in domestic legislation
• Signs may mark this area (example: a 30 mph speed limit sign)
• The definition is from UN-VCRT (1968)

Carriageway/Roadway

• This is the part of a road used by vehicular traffic (UN-VCRT, 1968)

Collector Highway

• A distributor road connecting low-to-moderate highways
• Often leads to or from residential areas

Highway

• The entire width between boundary lines of a road
• Publicly accessible for vehicular traffic

Combination of Vehicles

• Coupled vehicles traveling as a unit
• Referred to in UN-VCRT (1968)

Intersection

• This refers to any level crossroads, junctions, or forks
• It includes open spaces formed by those points (UN-VCRT, 1968)

Shoulder

• Strip on either side of the carriageway
• Commonly adjacent to the roadway

Sidewalk

• Paved walkway alongside a street

Through Highway

• A highway or a portion thereof for vehicular traffic
• Vehicles on intersecting highways must yield
• Vehicles may be required by law to yield

Thruway/Throughway

• A highway with limited entrances and exits
• Examples include expressways, freeways, and motorways
• Often know as Autobahn in Germany and autostrada in Italy

Traffic

• Derived from French and Italian terms
• Refers to the movement of people, goods, or vehicles (powered by combustion or animals) between locations for travel

Intersection (Definitions)

• Defined as the area within the prolongation (the extended lines) of the lateral curb lines
• Or, where no curb lines exist, it's defined by the lateral boundary lines of the roadways.
• The roadways connect to each other

3-Way Intersection

• Also known as T or Y intersections
• Connects three roadways

4-Way Intersection

• The most common type
• Involves the crossing of two roadways
• Two shapes are mentioned: regular and skewed

5-Way Intersection

• Involves the crossing of five roads
• Different lane design options are noted

6-Way Intersection

• Involves three streets, commonly two perpendicular and one diagonal

Staggered Intersection

• Involves two linked T-crossroads

Intersection Classifications by Traffic Control

• Controlled
• Uncontrolled
• Box Junction
• Cloverleaf

Controlled Intersection Types

• Yield-controlled
• Stop-controlled
• Traffic Circle

Uncontrolled Intersection

• Has no traffic signals or signs
• Vehicles must follow the right-of-way

Intersections - Right-of-Way

• Cars on the right usually have priority
• The vehicle that arrives at the intersection first is generally given the right of way

Box Junction

• Entry is prohibited unless the exit is clear
• It is a road traffic control measure

Cloverleaf

• This is a highway interchange
• Two highways cross with entry and exit ramps
• Its shape resembles a four-leaf clover

Traffic Management

• The application of processes and skills
• Planning, Organizing, Staffing, etc.
• Budgeting in traffic affairs

Types of Traffic Management

• Traditional engineering tools using devices for regulating or controlling traffic
• Intelligence transportation system (ITS)

Major Causes of Traffic Congestion

• Physical inadequacy
• Poor control measures
• Human errors
• Poor maintenance

Physical Inadequacy

• Lack of roads, narrow bridges, railroad crossings, and insufficient traffic facilities

Poor Control Measures

• Ineffective mechanical control devices
• Inefficient traffic officers
• Poor implementation of laws, rules, and regulations

Human Errors

• Slow drivers/poor driving habits
• Pedestrian errors
• Officer errors
• Poor planning
• Poor legislation

Poor Maintenance

• Road pavement and construction issues

Specific Traffic Problems

• Traffic buildup
• Traffic congestion
• Traffic jams
• Bottlenecks
• Gridlocks
• Accidents/collisions

Traffic Build-Up

• Gradual increase of traffic users in a specified road section

Traffic Congestion

• Conditions on road networks due to increasing use
• Slower speeds, longer times, and vehicular queueing

Traffic Jams

• Movement of traffic users (pedestrians and vehicles) is slow or stationary
• Blocked by an obstacle

Bottelnecks

• Narrow points in highways where congestion/traffic jams occur

Gridlocks

• Continuous vehicular queues in intersecting streets, bringing traffic completely to a standstill.

Accidents/Collisions

• Events or incidents causing unintended damage to property, injuries or death

Scope of Traffic Management

• All public surface facilities for movement of people and vehicles
• Provision for controlling traffic flow
• Allotment of parking lots/places

Agencies Involved in Traffic Management

• Department of Transportation
• City/Municipal engineers' Office
• Department of Public Works and Highways (DPWH)
• Legislative (Congress/City or Municipal Boards)
• Philippine National Police (PNP)
• Traffic Management Bureaus (TMBs)
• Academic institutions
• Courts
• Public Information Offices
• Barangay Peacekeeping Action Team (BPAT)
• Citizen Support Groups
• Tri-Media (including the internet)

Pillars of Traffic

• Traffic Engineering
• Traffic Education
• Traffic Enforcement
• Traffic Environment
• Traffic Economy

Traffic Engineering

• Study of measuring traffic
• Study of fundamental traffic laws and generation
• Fact-finding, surveys, and recommendations regarding traffic rules, regulations.
• Supervising engineering maintenance of traffic control devices.
• Planning of traffic regulations

Traffic Education

• Act or processes of imparting or acquiring general knowledge concerning traffic.
• Includes training and practice of applying traffic safety knowledge.
• Develops traffic safety morality in individuals

Traffic Education (for children and adults)

• Elementary, Secondary and Higher Education
• Education for both children and adults
• Easier for adults to understand concepts

Traffic Education Methods

• Comprehensive
• Traditional
• Commentary Driving Method
• Simulated Conditions

Biorhythm

• Cycle of strength, endurance and courage
• Related to the 23-, 28-, or 33-day cycles for both men and women

• The intent is to inform or persuade the public to adopt safe traffic behaviors.

Considerations for Traffic Management

• Thorough checking procedures
• Safety of both motorists and pedestrians
• Timing, location & frequency of enforcement
