Mobility plan for Riga and Pieriga

Latvian Ministry of Transport
Riga and Pieriga

In September 2009 Witteveen+Bos started work on the Mobility Plan and Action Program for Riga and Pieriga for the Latvian Ministry of Transport. The project was to set up a mobility plan for the city of Riga and the surrounding region of 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.


The project was carried out by a consortium of Witteveen+Bos, NEA and Witteveen+Bos Latvia. From our office in Latvia we also engaged 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 was €700,000 and the lead time was one year. Our Riga office enjoyed good cooperation with the client and various local experts.

Multidisciplinary challenge

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


The project started off with an analysis of the current situation. The analysis was used to formulate a vision and define objectives for the mobility plan. The third phase consisted of traffic modelling to obtain a transparent picture of the bottlenecks. In the next step three variants for the future traffic and transport system were developed. The variants consist of development plans for all transport modalities, the infrastructure (including the seaport and airport) and the management and organisation of these matters. Out of the three variants the preferred variant was further elaborated in greater detail and accompanied by a Strategic Environmental Impact Assessment (SEIA). An action programme that includes measures for the short, medium and long term was based on the preferred variant
