Transport planning and
road design
We offer the following services:
1. Road design
- Project documentation of traffic structures
- Project documentation for all design stages
- Highway and motorway - design and reconstruction works
- Through road design
- Design in cities - streets, squares, paved areas, public areas
- Car park and servicing areas design
- Traffic circulation in car parks and underground garages
- Coordination of activities within the project design
- Engineering
- Ground shaping
2. Transport planning
- Trip generation model (generated traffic calculations - in accordance with Czech standards, municipal regulations and trip generation model)
- Advanced trip modelling for shopping centres, residential buildings, offices, hotels, entertainment facilities, multi use buildings and city boroughs.
- Arrival and departure patterns, peak hours, modal split, car occupancy, etc.
- Parking assessment (in accordance with Czech standards, municipal regulations and the advanced trip generation model)
- Traffic assignment, highway/capacity assessment
- Traffic distribution
- Organisation of traffic surveys
- Traffic assignment - existing/new traffic network
- Capacity assessment
- Transport/traffic modelling - microscopic / macroscopic
- Transport assessment reports
- Road/highway design
- City logistics
- Assessment of existing goods distribution and fright transport systems
- Proposal of city logistic systems for a particular city
3. OmniTRANS, the transport planning and modelling software - sole distributor for the Czech and Slovak republic.
PBAI Prague is a sole distributor of OmniTRANS, the macroscopic modelling software. The software is suitable for modelling traffic in a whole country, a city, a town or small area.
- OmniTRANS can assess all transport modes including cars, public transport, pedestrians, cyclists, etc,
- Can test various scenarios of transport demand and network provision,
- Offers an advanced graphical output,
- Helps display traffic bottlenecks and find optimal solutions,
- Can assess new developments and their impact on new/existing traffic network,
- Provides analysis and optimisation of variants.
4. Languages - We can provide all documentation, drawings and reports in Czech and/or English.
ROAD AND HIGHWAY DESIGN
We carry out road and highway designs for all project design stages, even with a technical feasibility assessment within the first design stages and also pre-negotiation with the relevant authorities.
As a main designer, we can provide coordination of all related project tasks (bridge structures, relaying of utility services, etc). Within these engineering tasks, we can pre-negotiate the appropriate solutions with relevant authorities and utility operators and incorporate their requirements into the design.
We can provide site supervision during the construction.
Feasibility study - variant solution of servicing roads of a multi use centre
A roundabout design on a secondary II/348 road in Štoky - planning permit documentation
Layout drawing of a frontage road and a car park - Penny Market Podbořany
TRIP GENERATION MODEL
The trip generation model is used in the early design stages for estimating the future traffic load, parking demand and visitation generated by the new development. The enhanced model is based on past statistical data collected from similar developments.
The trip generation model calculates the following:
- The total traffic demand generated by the new development,
- Current parking demand,
- Traffic peak hour,
- Visitation of the development,
- Pattern of arrivals and departures,
- Two variants for weekdays and Saturdays
- The model can be applied for multi use developments.
CAPACITY CALCULATIONS OF VARIOUS TRAFFIC NETWORK ELEMENTS
- Determination of a bottleneck within a traffic network
- Road capacity calculations
- Capacity calculations of roundabouts, 3-way and 4-way intersections
- Traffic modelling of all types of junctions and intersections using advanced software tools.
- Modelling of signalized junctions (stand alone junctions, junctions in coordination)
- Determination of the degree of saturation of roads or junction arms.
- Traffic quality level of roads or junction arms.
