Database Department is responsible for the management, collection, updating and analysis of the data referring to roads, traffic, traffic signage and equipment, traffic accidents, railway crossings, structures and unstable terrains, commercial facilities. Based on the collected data, it prepares reports on average annual daily traffic as well as tables on traffic volumes on I and II category roads.
Entire work of the Department is covered by employees with high education in the field of electrical engineering, traffic and transport engineering and civil engineering in order to reach the set objectives and implement new projects.
The Department covers the following databases on regular basis: roads, bridges, tunnels, landslides, traffic counting, dangerous locations, railway crossings and traffic signage and equipment.
Database on Roads contains the main data about the state roads in the Republic of Serbia and the recordings and situation of road inventory. Among other issues, it contains the data on road routes, composition and dimensions of the carriageway, data on climate zones, size and structure of traffic volume, parameters of flow, congestion speed, etc.
Data are prepared for various services and designs, namely, design companies most often require the surveying of longitudinal IRI and rutting from the Database on Roads.
Database on Bridges defines all elements of the bridge which is inspected, with the instructions for inspection and evaluation of its condition, bearing capacity and the listing of the existing damages. The database contains applications for the determination of bridge class pursuant to the maintenance priority as well as the potentials for the preparation of activity plans.
Database on Tunnels, after inserting data on inventories, each tunnel is described by defining the elements for the description, estimation of the condition and routine maintenance. Based on all weighted points, DoT application is used to determine the rating of the tunnel pursuant to the maintenance priorities.
Database on Landslides contains defined methodology for the evaluation of dangers and evaluation of risks expressed as processed ratings, in order to ensure unobstructed functionality of traffic.
Database on Traffic Counting. Establishment of the Database on Traffic Counting implies systematic collection of data on:
- volume and structure of the traffic flow,
- spatial misbalance of the traffic flow and
- time misbalance of the traffic flow (hourly, daily, weekly, annual).
Publication on traffic counting is issued on paper and in electronic form and it is presented on the Website every year.
Geographic Information System (GIS) represents the visualization of geospatial data and enables the creation of spatial data as well as spatial analysis, interpretation of information and their connection. All alphanumeric databases keep records which can be geographically presented.
Geodatabase of the enterprise is also available on mobile Android application that contains almost all spatial data sets of the PERS. Spatial data sets are stored and organized with adequate attributes, through which the situation on the road network is monitored with the primary task to collect all spatial and non-spatial data related with the PERS road network.
• prostornim neravnomernostima saobraćajnog toka i
• vremenskim neravnomernostima saobraćajnog toka (časovnim, dnevnim, sedmičnim, mesečnim, godišnjim).
Prezentacija podataka o brojanju saobraćaja izdaje se u štampanom i elektronskom obliku, i prikazuje se na veb sajtu svake godine.
Geoprostorni informacioni sistem (GIS), predstavlja vizuelizaciju geoprostornih podataka i omogućava kreiranje prostornih podataka, kao i prostornu analizu, tumačenje informacija i njihovo povezivanje. Sve alfanumeričke baze podataka čuvaju podatke koji mogu biti predstavljeni geografski.
Geobaza podataka preduzeća dostupna je i na mobilnoj android aplikaciji, koja sadrži skoro sve prostorne skupove podataka JPPS-a. Prostorni skupovi podataka se skladište i organizuju sa odgovarajućim atributima, čime se vrše praćenja stanja mreže puteva sa primarnim zadatkom prikupljanja svih prostornih i neprostornih podataka vezanih za mrežu puteva JPPS.
