Mobility plan for Riga and Pieriga

Traffic problems

The project area covers 6984 km2 and houses more than one million people, or 47 % of Latvia's total population. Riga has a large seaport and an international airport and is an important hub along international transport routes. A diversity of traffic problems confront the city. The main problems concern planning and management of public transport and the road and rail networks, the limited capacity of Daugava river crossings, a lack of road safety and a shortage of facilities for cyclists and pedestrians.


Witteveen+Bos is heading the consortium. From our office in Latvia we are also engaging local subcontractors to work on the project. Although not the cheapest bidder, the consortium won the contract because its approach was in tune with the client's wishes. The total budget for the project is €700,000 and the lead time is one year.

Four themes

Besides the project team, the project management consists of a squad of eleven experts who input knowledge of their own specialisations. The experts are working together on four themes: traffic engineering, public transport, traffic modelling, and other aspects (including the environment, institutional organisation and legislation). There is local collaboration with various Latvian experts and with the client's working group and steering committee.

Witteveen+Bos has named a young project engineer as project coordinator to support the project leader. Her task is to oversee project organisation, communication, reporting and planning. It is a challenging task because of the numerous different parties involved in the project. She travels regularly from the Netherlands to Riga to cement good interaction with the client and Latvian experts. More experienced professionals have also been deployed and they are responsible for running the experts who are working on the four themes and for substantive inputs in this field.


The project starts with an analysis of the current situation. The analysis will be used to formulate a vision and define objectives for the mobility plan. The third phase consists of traffic modelling to obtain a transparent picture of the bottlenecks. The next step will be to develop variants for the future traffic and transport system. The variants will consist of plans for all transport modalities, the infrastructure (including the seaport and airport) and the management and the organisation of these matters. One preferred variant will be worked out in greater detail. An action programme that includes measures for the first five years will be set down for the preferred variant in the final phase.

Multidisciplinary challenge

Preparation of the mobility plan requires an integral approach and the deployment of numerous different disciplines ranging from traffic management and planning, traffic plans, traffic modelling and public transport all the way through to marketing, transport economics, environmental technology, legislation, institutional analysis and information technology (intelligent transport systems/passenger information systems). An extra dimension to this challenge is that the work is being carried out in a foreign country.
