Highway Planning

DEALSWITH THE SELECTION OF PROJECTSFOR DESIGN AND CONSTRUCTION AN ONGOING PROCESS THAT SEEKS TO ADDRESS THE TRANSPORT NEEDS OF THE INHABITANTS OF THE AREA, AND WITH THE AID OF A PROCESS OF CONSULTATION WITH ALL RELEVANT GROUPS, STRIVES TO IDENTIFY AND IMPLEMENT AN APPROPRIATE PLAN TO MEET THESENEEDS.

Travel data

THE COLLECTION OF HISTORICAL TRAFFIC DATA COVERING THE GEOGRAPHICAL AREA OF INTEREST.

Demand of highway scheme

STEMS FROM THE REQUIREMENTS OF PEOPLE TO TRAVEL FROM ONE LOCATION TO ANOTHER IN ORDER TO PERFORM THE ACTIVITIES THATMAKEUPTHEIREVERYDAYLIVES.

Land use transportation approach

THE MANAGEMENT OF LAND USE PLANNING IS SEEN AS THE SOLUTION TO CONTROLLING THE DEMAND FOR BOTH ROAD SPACE AND OF MAJOR PUBLIC TRANSPORTIMPROVEMENTS

Demand management approach

THIS ENTAILS PLANNING FOR THE FUTURE BY MANAGING DEMAND MORE EFFECTIVELY ON THE EXISTING ROAD NETWORK RATHER THAN CONSTRUCTINGNEWROADLINKS

Transport Centered Approach

THE STRATEGY WILL EMPHASIZE THE IMPORTANCE OF BUS AND RAIL-BASED IMPROVEMENTS AS THE PREFERRED WAY OF COPING WITH INCREASEDT RANSPORT DEMAND.

Car centered approach

IT SEEKS TO CATER FOR FUTURE INCREASES IN TRAFFIC DEMAND THROUGH THE CONSTRUCTION OF BIGGER AND BETTER ROADS, BE THEY INTER-URBAN OR INTRA-URBANLINKS.

Transportation survey

TRANSPORT PLANNERS FIRST DEFINE THE STUDY AREA'S PHYSICAL BOUNDARIES. TRAVEL PATTERNS ARE ANALYZED BY PROFILING THE ORIGIN AND DESTINATION (OD) OF ALL JOURNEYS, ALONG WITH THE MODE AND PURPOSEOFEACHTRIP.

Models

ARE DEVELOPED TO TRANSLATE THE INFORMATION ON EXISTING TRAVEL PATTERNS AND LAND-USE PROFILES INTO A PROFILE OF FUTURE TRANSPORT REQUIREMENTS FOR THE STUDY AREA

Freeways

IS A DIVIDED HIGHWAY WITH FULLY CONTROLLED ACCESS. ACCESS TO A FREEWAY IS MADE WITHOUT USE OF ATGRADE INTERSECTIONS.

expressways

THEY ARE SUPERIOR TYPE OF HIGHWAYS AND ARE DESIGNED FOR HIGH SPEEDS (120 KM/HR IS COMMON), HIGH TRAFFIC VOLUME AND SAFETY, PROVIDED WITH GRADE SEPARATIONS ATINTERSECTIONS.

arterials

PROVIDE DIRECT SERVICE TO MAJOR POPULATION CENTERS DENOTING A STREET PRIMARILY MEANT FOR THROUGH TRAFFIC USUALLYONACONTINUOUSROUTE.

Local streets

CONNECT VARIOUS REGIONS OF A MUNICIPALITY AND TIE INTO THE SYSTEM OF COLLECTORS

collector streets

DIRECT SERVICE TOTOWNS AND LINK UPWITH ARTERIALS. THESE ARE STREETS INTENDED FOR COLLECTING AND DISTRIBUTING TRAFFIC TO AND FROM LOCAL STREETS AND ALSO FOR PROVIDING ACCESS TO ARTERIAL STREETS.

National higway

MAIN TRAFFIC ROUTES CONNECTING PROVINCIAL CAPITALS WITH IMPORTANT COMMERCIAL CENTERS, NATIONAL AIRPORTS, NATIONAL SEAPORTS, AND NATIONAL PARKS AND ROADS OF MILITARY IMPORTANCE, WHICH MAY BE SO DESIGNATEDBY THEPRESIDENT.

Provincial roads

CONNECT CITIES AND MUNICIPALITIES WITHOUT TRAVERSINGNATIONALROADS.

Municipal and city roads

THIS ROADS THAT CONNECT TO PROVINCIAL AND NATIONAL ROADS ROADS THAT PROVIDE AN INTER-BARANGAY CONNECTIONS TO MAJOR MUNICIPAL AND CITY INFRASTRUCTURE WITHOUT TRAVERSINGPROVINCIALROADS

road patterns

rectangular

ALSO CALLED GRID OR BLOCK PATTERN. THE WHOLE AREA IS DIVIDED INTO GRIDS OR BLOCKS RUNNING PERPENDICULARLY INTO EACH OTHER.

radial

• DIVIDES FURTHER INTO THREE PATTERNS KNOWN AS STAR BLOCK PATTERN OR STAR CIRCULAR PATTERN AND STAR GRID PATTERN.

minimum travel pattern

IN THIS ROAD PATTERN, CITY IS CONTENTED BY SECTOR CENTER, SUBURBAN CENTER AND NEIGHBORHOOD CENTER BY THE ROAD WHICH REQUIRED MINIMUM TO CONNECT THE CITY

hexagonal pattern

THE ROADS NETWORKS RESEMBLE OR FORMS A HEXAGON

map study

reconnaissance survey

IN THIS PHASE OF STUDY, SEVERAL FEASIBLE ROUTES MAY BE IDENTIFIED AND THE MOST FEASIBLE ROUTES FOR FURTHER DETAILED STUDIES. FEATURES INDICATED ON THE MAP WILL ALSO BE CONFIRMED.

preliminary location survey

THIS STAGE, THE POSITIONS OF THE FEASIBLE ROUTES ARE SET AS CLOSELY AS POSSIBLE BY ESTABLISHING ALL THE CONTROL POINTS AND DETERMINING PRELIMINARY VERTICAL AND HORIZONTAL ALIGNMENTS FOR EACH.
