Macroscopic model of vehicle transport of the Czech Republic

The company CityPlan processed, maintains and continuously updates the transport model of vehicle transport of the Czech Republic in the environment of PTV VISUM of the company PTV Karlsruhe. Based on this national model, more detailed traffic models are created for individual regions and cities.

Model of the Czech Republic contains over: 7 619 traffic zones, 62 718 road sections, 44 373 nodes, 12 286 counting profiles, 364 374 intersection movements.

Usage of the transport model

Transport modeling is a modern and highly technical discipline of engineering. Although modeling itself is quite demanding and requires a high degree of expertise of the subject, the outputs of transport models are very clear and provide answers on issues associated with analysis of the current state, as well as the forecasted state. 

Usage of the transport model is suitable for:

• building new transport infrastructure
  
• decision-making on variants and categories of roads in Transport Plans and Master Plans
  
• capacity assessment of the road network and intersection nodes
  
• optimisation of public transport
  
• organisation of public transport of passengers
  
• implementation of new public transport routes or lines
  

 Furthermore, the transport model can be utilised for regulatory measures in transport, such as:

• regulation of traffic on the network
  
• looping (establishing autonomous transport cells)
  
• establishing one-way roads
  
• other measures aimed at traffic calming of a preferred territory.
  

Analysis of modeled transport situation:

• localisation of optimal routes for traffic load
• capacitive load of the network – degree of saturation, decrease of speed
• load on various types of roads – transport performance on the network (D, R, I, II and III class)
• analysis of intersection movements
• analysis of road profiles, determination of transit relations
• variants of route leading
• load of PT lines/systems
• graphical timetables of lines
• performance statistics of public transport lines (PassHours, PassKm)
• time availability of stations/residents
• identification of major connecting nodes

National transport model consists of two main elements:

• Model of transport supply
• Model of transport demand

The transport model includes all roads on the territory of the Czech Republic divided into: Highways (D) Expressways (R) I class roads II class roads III class roads. The transport network is parameterised, i.e. each section is assigned a default type, speed, capacity, number of driving lanes, and other additional information, such as tolls, etc.

Model of transport demand

The model of transport demand contains all municipalities in the Czech Republic. The demand thus includes a complete matrix of vehicle transport journeys among all municipalities in the Czech Republic.

The matrix is calculated from the gravity model. Calculations of transport demand include computation of the matrix of distances and journey times among transport zones of a default and burdened road network.

These matrixes are in the next stage calibrated on counting profiles of the whole Czech Republic
 

Models of forecasted transport relations

The basic prognosis is processed until the year 2030, which is the expected horizon for completion of major investment projects for the road network of the Czech Republic. The prognosis of transport relations consists of two basic scenarios, which differ mainly in degree of motorisation and increase of the overall performance. Other characteristics remain the same for both scenarios.

Forecasted road network

The forecasted road network of the Czech Republic (and surrounding states) is processed for the horizon of the year 2030, assuming that all major highways and roads are constructed and operating. The model of the existing road network of the Czech Republic has been extended by all major investment actions affecting attractiveness of roads and distribution of traffic load, including the programme for construction of highways, expressways and I class roads.

Input characteristics:

• demographic distribution and composition of population
• location of employment opportunities
• quality of public transport connections
• average speed of public transport
• price for 1km long journey realised by public transport
• price for 1km long journey realised by a personal vehicle 

Prognosis may utilise other characteristics:

• development of international transit transport
  
• development of average performed distance of vehicles
  
• development of share of journeys to work on larger distances
  
• development of commercial and tourist relations
  
• development of motorisation degree
  
• development of the overall performance
  
• development of modal split between public transport and individual transport
  
• development of modal split between rail and road transport
  

The established transport model has relations to other models, such as:

• models of burden to the environment
• economic models – e.g. HDM-4
• on-line models of traffic management

Relations to other software

Transport models created in the program VISUM, which is a GIS application, are convertible to other GIS applications (ArcView, MapInfo).
The transport model of the Czech Republic and other consecutive models of cities and territories are created in the coordinate system S-JTSK.
