Infrastructure surveying and mapping

In the past few decades, traffic concentration and traffic volume have grown considerably both in developed and developing countries. The popularity of the car enabled vast number of families and businesses to travel thousands of miles annually. International trade, expending of logistics and e-commerce sectors stimulate the future increase of transport volumes. Transportation mobility however entailed many negative implications such as traffic congestion, unavailability of parking spaces, air and water pollution. 

Zesmill offers innovative geospatial solutions for road maintenance, better urban transportation planning, and logistics. We provide:

As we are instrumental in spatial data harvesting and thematic mapping, our company offers an array of cartographic products (maps and road graphs, GIS layers, geodatabases etc.), that help road maintenance, urban planning, and logistics professionals. 

Road maps

Road maps show a road network along with transport infrastructure:

  • road maps show highways, arterial and minor roads, tunnels, bridges and overpasses, streets and roadways in cities etc.
  • maps of roads by functional classification depict roadways color-coded according to their functional classification (in USA — highway, minor highway, freeway, collector, local; in UK — M, A, В, С, D, and U; in post-USSR countries — auto magistrals, international and national highways, oblast and local road, etc.)
  • road condition maps are based on road inventory data
  • rail transport maps shows single- and double-track, electrified and non-electrified railways, stations, marshalling (hump) yards, railway depots etc.

Traffic mapping. Traffic flow and isochrone maps

Traffic flow maps show the average day, month, or annual traffic on roads or major city streets. As collection of traffic data based on statistical methods it required periodical long- and short-term studies. Reliable data can be obtained with automatic traffic counters. 

Isochrone maps represent automobile, railroad, or public transit travel times from and to selected urban and industrial areas, public centers, airports etc. They are overlaid on road network maps or compared with master plans materials to determine transportation needs and understand the underlying characteristics of travel. 

Using isochrone maps and traffic volume data gives planners ability to model the impacts of new developments and improvements in the transportation system. They also can be useful for public transit planning, logistics management, site selection and feasibility studies.

To collect the necessary data, Zesmill’s field team employs various techniques like origin-destination surveys, obtaining the real-time traffic data by locating vehicles via mobile apps and GPS along with roadway segment-specific traffic counting using UAVs, video cameras, and pneumatic (road tube) devices.
