Lesson 2 Traffic Management Lesson 2.1 Fundamentals of Traffic Management Concepts Traffic Management is best understood by understanding the following commonly used words and terminologies. Some of these are defined according to their “operational definitions” and some are defined based on their general definitions. However, most of these terminologies are defined base on Chapter 1, Article 1 of the United Nations Vienna Convention on Road Traffic (UN-VCRT) in 1968. The definitions of the UN are also adopted by Department of Public Works and Highways (DPWH) on their “Highway Safety Design Standards” published in 2012. Highway. The entire width between the boundary of everyway dedicated to a public authority when any part of the way is open to the use of the public for purposes of vehicular traffic, whether or not the public authority is maintaining the way. Or, highways refer to any roads, streets, boulevards, or avenues used as a public thoroughfare. Articulated Vehicle. It means a combination of vehicles comprising a motor vehicle and a semi-trailer coupled to motor vehicle. (UN-VCRT, 1968) Light Trailer. any trailer of a permissible maximum weight not exceeding 750kg. Semi-Trailer. any trailer designed to be coupled to a motor- vehicle in such a way that part of it rests on the motor vehicle and that a substantial part of its weight and of the weight of its load is borne by the motor vehicle. Permissible Maximum Weight. it means the maximum weight of the laden vehicle declared permissible by the competent authority of the State in which the vehicle is registered. Power Driven Vehicle. It means any self propelled road vehicle, other than a a territories of contracting parties. Built-up Area. It refers to an area with entries and exits especially sign posted. Management.

Means any two-wheeled vehicle, with or without a side-car, which is equipped with propelling engine. Motor Vehicle. Any power-driven vehicle which is normally used for carrying persons or goods by road or for drawing, on the road, vehicle used for the carriage of person or goods. This term embraces trolley-buses, that is to say, vehicles connected to an electric conductor and not rail-borne. It does not cover vehicles, such as agricultural tractors, which are only incidentally used for carrying persons or goods by roads or for drawing, on the road, vehicles used for the carriage of person or goods. Arterial Highways/Roads. These are high-capacity urban roads that direct traffic from the collector roads to expressways or freeways. It also refers to a highway that is used primarily by through traffic. Motorway. It means a road specially designed and built for motor traffic, which does not serve properties bordering on it, and which: Is provided, except at special points or temporarily, with separate carriageways for the two directions of traffic separated from each other either by a dividing strip not intended for traffic oor, exceptionally, by other means; Does not cross at level with any road, railways or tramway track, or foot path; and Specially signed posted as a motorway. Collector Road. Also known as the Collector Highway or Distributor Road which connects low-to-moderate highways or roads to arterial highways such as those entering residential properties. It also refers to a highway that serves primarily to funnel traffic from one local highway to another or between arterial and local highways Lane. One of the longitudinal strips from which the carriageway can be divided, whether or not defined by longitudinal road marking. Parked. A vehicle is said to be parked if it is stationary for the period during which the vehicle is not limited to the time needed to pick up or set down persons or goods. Level-crossing. Means any level intersection between a road and a railway or tramway track with its own track formation. Roadway. Refers to the part of the traffic way over which motor vehicle pass otherwise known as Carriageway. Roads are classified as: a. National Road. These are roads/streets interconnecting provinces and/or cities. b. Provincial Road. Roads or streets interconnecting municipalities or cities within the province. c. City Road. Road/street interconnecting barangays within a city d. Municipal Road. Road/street interconnecting barangays within a city. e. Barangay Road. Road/street located within barangay which connects sitios or places within a barangay Road. Refers to the entire surface of any street open to public traffic. It also includes shoulder and sidewalk. hence, to DPWH, the “road” is synonymous to traffic way. Shoulder. Refer to either side of the roadway, especially along highways. Road Users. It shall mean any person using the road including drivers, pedestrian, cyclist and commuters. Sidewalks. Refer to the paved walkway along the side of a street. It also means the area determined as follows: 1. On the side of a highway which has shoulder, a sidewalk is that portion of the highway between the outside lateral line of the shoulder and the adjacent property line capable of being used by a pedestrian.  2. On the side of the highway which has no shoulder, a sidewalk is that portion of the highway between the lateral line of the roadway and the adjacent property line capable of being used by a pedestrian. Traffic. Refers to the movement of persons, goods, or vehicles either powered by combustion system or animal drawn, from one place to another for the purpose of travel. Via obsolete French Trafique from Old Italian Traffico, from Traficare which means “to carry on trade.“ Traffic way. Refers to the entire width between boundary line of every way or place of which any part is open to the use of the public for purposes of vehicular traffic as a matter of right or custom. It is also synonymous to public way. Intersection. is defined as the area embraced within the prolongation or connection of the lateral curb Intersection. the area embraced within the prolongation or connection of the lateral curb lines, or, if none, then the lateral boundary lines of the roadways of two highways which join one another at, or approximately at, right angles, or the area within which vehicles travelling upon different highways joining at any other angle may come in conflict. Classification of Intersections According to Number of Intersecting Roads: 1. 3-way Intersection- it is commonly known as the T or Y crossroad which links three roads. 2. 4-way Intersection- the most common type which involve the crossings of two roadways. It is either a regular intersection when the two roads cross perpendicularly and it is called skewed intersection when the two roads cross at different angles. 3. 5-way Intersection-involves the crossing of five roads. This type is the least common. 4. 6-way Intersection- it involves the crossing of three streets most often two perpendicular roads and one diagonal road. This type is very rare. 5. Staggered Intersection- involves two successive T Crossroads.
