Urban Europe Policy Brief on e4-share available online (September 2018)

Based on the project findings, a policy brief – developed in collaboration with JPI-Urban Europe – was published. Read more about the potential of shared mobility services as well as on policy recommendations for urban planners and operators:


Final event: 4th BieM discussion- and networking event in Vienna (12th December 2017)

On 12th of December 2017, the results of the e4-share project were presented and discussed at the final stakeholder event within the framework of the ‘fireside chat’ discussion series – organized by “BieM – National Initiative eMobility Austria” in Vienna.

After a short key note on e4share, held by Bin Hu (AIT), more than 50 guests from the fields of car sharing operators, city administration, public transport providers, transport research and others, discussed the topic of (electric) car sharing, the related  urban challenges and strategies and the providers’ and city administration’s aims and recommendations for future urban mobility.

The panel included Markus Gansterer (VCÖ), Marlene Hawelka (tbw research), Alexander Hovorka (car2go), Bin Hu (AIT), Martin Mai (Stadtauto.at) and Gregor Stratil-Sauer (City of Vienna, Mobility Department).

Final e4-share meeting in Vienna (19th to 20th of September 2017)

At the end of September 2017, the final project meeting took place again at the University of Vienna – the place of the project leader.

The three priorities of the closing event were:

  1. a summary of the work done so far
  2. the next steps open to do until October 2017 and
  3. the outlook on the exploitation – final Stakeholder-workshop, publications, follow-up project.

The final Stakeholder-event will take place within the framework of the discussion series – organized by “BieM – National Initiative eMobility Austria” on 12th December 2017 in Vienna.

Survey on incentives offered to car-users (May to July 2017) – offline

Do you regularly use one of the commercial CarSharing services in Vienna or other cities?
Which tasks would you take for a functioning CarSharing operation?
What would you have offered?

If you can answer the first question with YES, we ask you to take part in the following survey (about 10 minutes / GERMAN):

e4share survey

The survey is conducted within the framework of the research project “e4-share“.
The evaluations are exclusively used within the scope of the research activities of the project partners and are not passed on to CarSharing operators.
The evaluations are done anonymously.

Third JPI Urban Europe Projects Meeting (Brussels, 31th May 2017)

At the end of May, JPI Urban Europe again invited all funded projects and other key stakeholders in the JPI Urban Europe community to the third Projects Meeting – this time in Brussels at La Tricoterie. More than 100 representatives from the JPI Urban Europe projects took part.

This time the focus was laid on support activities and training sessions in specific areas, for example how to approach companies. Like the meetings before, the meeting provided an opportunity for the project partners to meet and to share know-how, learn from results of other projects, discuss strategic development and also to look for future cooperation partners.

Sixth e4-share meeting in Bologna (13th to 14th of February 2017)

The focus of the sixth project meeting at the premises of Alma Mater University of Bologna was laid on the results of the station-based models, further KPI specifications especially for ad-hoc car-sharing, research results and next steps regarding incentives for users to take on management tasks. There was a discussion on implementation rules into the models and algorithms as the upcoming months until the end of the project will also be dedicated to evaluating and validating the models and performance using simulations and impact assessment. Another focus was the discussion on scientific dissemination as well as publications for the general  public which has to be prepared within the next months.

Fifth e4-share meeting in Vienna: starting the last project year

The fifth project meeting took place on September 19th and 20th 2016 at the premises of tbw research in Vienna.

As two thirds of the project duration are already completed, the focus was laid on results, constraints for the free-floating models, KPI specification and simulation. Furthermore, potential incentives to car-sharing users have been considered as they will need to be integrated into the models. Also it was discussed how to make use of the project results in terms of follow-up projects as well as how to present intermediate project outcomes to stakeholders in order to verify their practical relevance.

e4-share JPI Urban Europe Projects Meeting

Project meeting JPI Urban Europe – come together event in Amsterdam in order for all projects to meet representatives from management and advisory boards.

On April 14, 2016 the second JPI Urban Europe Projects Meeting was held in Amsterdam. The meeting was arranged in order for all the projects calls (pilot call I & II as ERA-NET Cofund „Smart Cities and Communities“) and to meet and connect with the relevant stakeholders of the community.
The Project meeting strongly supported networking among projects partners as well as facilitating learning more about the projects and to give feedback and inform about JPI Urban Europe. For the e4-share project three representatives from Austria and Italy were attending.

Fourth e4-share meeting in Brussels

From 16th to 17th of February 2016 the project team met in Brussels at the premises of ULB to discuss the current status of the methods and models so far developed already resembling solution approaches in terms of algorithms for operational management of station-based e-car-sharing systems and integer linear programming formulations for finding optimal locations for charging stations in an electric car sharing network.
The so far defined approaches with all their assumptions have been discussed and contrasted with data received from stakeholders in the fields of charging infrastructure and car-sharing.

 Third e4-share meeting in Vienna

From 31st of August to 1st of September 2015 the third project meeting was held at AIT in Vienna including the participation at OR2015, the annual “International Conference on Operations Research”, organised by the German Operations Research Society (GOR) together with the Austrian Operations Research Society (ÖGOR) and the Swiss Operations Research Society (ASRO/SVOR) at the University of Vienna from September 1-4, 2015. The project team mainly worked on the past activities regarding the Problem Definition and Modelling – mathematical models and exact methods for the station-based systems and constraints for the ad-hoc car sharing systems. Furthermore, the project team discussed benchmark instances, the results of the literature review, the current state regarding the stakeholder dialogue and preliminary results in the field of solution approaches.


 Second e4-share meeting in Bologna

From 23rd to 24th of February the second project meeting was held at the University of Bologna. The project team mainly discussed the academic literature review. The objective of the academic literature review is to gain an overview of already existing approaches but also to gain a detailed problem definition of the problems that should be solved within e4share. Also preliminary solutions approaches were discussed during the meeting. In general, optimization solutions for the principle design of electric car sharing systems, the location of charging stations and the relocation of electric cars will be the main focus within the first phase of the project.

Kick-Off Meeting in October, 2014

In October 2014, the e4-share project consortium met for its kick-off meeting in Vienna. Since then, the team members in Bologna, Brussels and Vienna are working on the identification of stakeholders, gathering of input data and the problem definition of different car-sharing systems.
