Digitization of Road Directory of Pakistan
Client: National Transport Research Center, Ministry of Communication, Government of Pakistan
Pakistan have roughly 271,000 km road network according to Pakistan Economic Survey, 2017. These roads are administered at different administrative levels include Federal, Provincial and Local Government Level. To date, unified directory of these roads could not be developed. National Transport Research Centre (NTRC) under the Ministry of Communications, Government of Pakistan aimed to provide much needed Research and Development (R&D) support for planning and appraisal of transport sector projects /plans in a coordinated and cost-effective manner. Considering that there is no robust digital database of the country road network wherein information pertaining to various types of roads owned by spatially distinct i.e., national, provincial and local entities is available, NTRC initiated a project to Digitise the Roads Directory in the Country. The Urban Unit was awarded the project through competitive bidding. The unit was tasked with developing the a digital road directory that not just include geographic location of the roads, but also contain all the necessary attributes of the roads that are required for transportation planning. Information pertaining to alignment, length, width, ownership is attributed to the existing National Highway Network, Provincial Highway Network, District Roads, Feeder Roads, Municipal Roads, Urban Roads etc. Project area includes all Pakistan including Punjab, Sindh, Balochistan, Khyber Pakhtunkhwa, Gilgit Baltistan, Azad Jammu & Kashmir, Federally Administered Tribal areas.
The main objective of this project is to develop a geo-database and road directory through digitization of roads spatially located across Pakistan. The Urban Unit has considered all the TORs and has provided assistance in the development of the geo-database through road digitization, verification of digitized road, integration of road attributes and spatial classification of the roads. The methodology adopted by Urban Unit consists of Seven phases. Phase I includes Classification of Roads for Standardization of Road Assets and Assigning Unique Numbers (ID) / Code assigned to each road / link. Phase II includes Base Data Development through Digitization of Road Network at 1:2000 . Phase III includes Collection of Secondary Information from relevant authorities through Android Based evidence and Integration within Base Data. Phase IV includes quality Assurance and Integrated Node Link Network Development. Phase V includes Development of Web Portal/ Dashboard for Visualization, Query, Analysis and Field Survey Facilitation. Phase VI includes Android Based Field Survey for Verification of Roads and Capacity Building of NTRC staff to use Web Portal and Android App and last Phase VII will incorporate the development of District wise Roads Records.
Presently, multiple road classification systems are being followed by various national, provincial and local public Presently, multiple road classification systems are being followed by various national, provincial and local public organizations. Consequently, there is a confusion not only among the organizations but also within the planning standards and manuals followed by development agencies. Evidence include Ring Road Vs Motorway, farm to market vs district or Khadim e Punjab Rural roads, etc. After review and study of global best practices, the existing roads is classified into hierarchical system of roads. The classification allows standardization of the variant nomenclature of the roads adopted by relevant authorities as per will; thus, allowing all relevant authorities both at national and provincial level to adopt same terminology and hierarchical system of roads. Therefore, For Pakistan, roads are classified into six distinct categories according to the function they serve and attributes they possess. Classification of roads based on its functionality and attributes is given in the figure below.
