A Bruns, IVM, DE


The paper explores current problems of internet based car pooling platforms and offers practical solutions to enhance the performance. It shows that key factors are integration of CPP into traffic planning as well as cross linking existing providers.


The paper analyses the current main problems of public internet based car pooling platforms (CPP) and shows ways of how to increase the effectiveness of CPP as a means of mobility management (MM), focussing on integrated traffic planning concepts and especially public transport as well as cross linking the numerous existing providers by means of a commonly developed interface. The paper hereby refers to the research project Potentials an options of cross linking internet based car pooling platforms for commuters on behalf of the German Federal Ministry of Transport, Building and Urban Development.

Carpooling (seen as ridesharing on a regular basis especially for commuting) is a very popular element of MM plans or concepts in. It is seen as an effective means both to increase accessibility and to reduce traffic volumes as well as commuting costs for those employees who cannot access their work places with public transport or by bike. Hence, several CPP have been introduced by public institutions as well as by private entrepreneurs since year 2000. But the evaluation of numbers of users and successfully matched car pools showed that the current performance does not meet the expectations by far and thus raised the question of causes and possible solutions focussing on possibilities of enhancing the concept of CPP under existing conditions out of a traffic planning perspective.

The research results show that main problems nowadays are: competition of numerous providers with different service quality and without central access and a general lack of publicity. Above that on the side of traffic planning CPP is very seldom a part of comprehensive traffic planning and especially public transport concepts.

Within the research project under participation of all affected players several solutions have been developed e.g. a common interface for cross linking CPP providers and connect them to a common "metaportal", possibilities of integrating CPP in MM concepts as well as local traffic plans, standards for service quality and new marketing opportunities. Above that the reduction potential towards commuting has been analysed for Germany and in-depth for two regions based on traffic modeling.

The presentation will highlight the solutions of the research project focussing on the potentials of integrating CPP in traffic planning/ MM concepts as well as on showing ways to increase the effectiveness of CPP by cross linking systems and introducing a metaportal. Morover in-depth information about additional results especially the potentials of car pooling in terms of traffic flow and CO2 reduction will be provided.

It is shown that to enhance the performance especially of publicly accessible CPP cooperation of relevant players is crucial. Beyond analysis the paper offers practical solutions on technical and organisational level. Especially the developed technical interface offers the opportunity to cross link providers even on a European level. As CPP are a common means within MM concepts all over Europe the results may also offer interesting perspectives for other European countries. Above that the empirical data from an online survey shows the differences between car poolers and ridesharers in general and therefore is a basis for enhancing CPP concepts.
