Five years project – three stages:

first stage: service planning, infrastructural

implementation, financial feasibility and

demand analysis;

second stage: supervision of the starting

phase and effective users response;

third stage: opening of the service to a wider

area of Rome

E- GO Car Sharing First Stage (2)

Designed as a “one way” station based car sharing:

Ex-ante survey - On-line RP and SP survey to 1,200

potential users: 960 respondents

RP section:

socio-economic characteristics and mobility habits;

behavioural attitudes (green attitude, out of pocket, sharing

attitude)

SP section:

evaluation 3 fee scenarios

Mobility characteristics

Distances:

34% of the sample performs a short-distance home-university trip

(less or equal then 5 km); 28% a medium-distance trip (more than 5

km, but less or equal than 15 km); 16% a long-distance trip (more than

15 km but less or equal than 25 km). The remaining ones perform a

trip longer than 25 km;

Modal shift:

off-site students mostly choose the public transport alternative for

their trips (67%);

for on-site students there is a comparable choice between the

automobile and the public transport;

Other users: higher values of private vehicle (70%)

Other:

92% of respondents has a driving license;

public transport subscription is not diffused: about 52% of the sample

declared to not have any kind of subscription.5/21


Ingegneria

Adoption of the new car sharing system

For home-university trips:

80% (students and off-site students); 83% (others);

71% CS integrated with public transport

The adoption decreases with the increase of the distances

to be travelled (85% d < 5km; 55% d > 50 km);

Frequency: 3 days/week

For other trip purposes:

86%; 92% (off-site students);

No difference between male/female;

Reduction of the adoption of CS with the increase of

the household income:

Out of pocket: less than 50 € per month for the 80% of the

students.

Green attitude How much users are environmental conscious and open

minded about new sustainable transport modes?

GA is not linked to the user’s gender, the economic conditions and to

the level of education;

about 70% of respondents over 45 years old declared to be aware of

environment;

public transport users show higher GA values.

Sharing attitude Cohousing and car sharing – car pooling use:

SA decreases with the increase of age and income;

Males are slightly more opened to share goods and services than

females from our sample (respectively 60% full sharing attitude and

47% full sharing attitude);

Green Attitude and SA are positively correlated.

SP survey

Fee scenarios:

After the proposed fees, respondents are invited to express

their willingness to subscribe the proposed service:

about the 24% of the respondents declared to be interested in using the

proposed service for home-University trips;

the 28% for not home-work trips closed to University

E- GO Car Sharing First Stage: moving to

free floating

Pilot test: from mid-September 2016 to the end of

November 2016:

100 users resulted available from the ex-ante survey involved

in using the service for free;

Critical issues:

Recharge stations not available;

Security and policy issues: if the recharge station is kept by

an E-GO vehicle: damages by owners of other electric vehicles;

Safety issues.

Second survey - On-line RP and SP survey

Demand modelling (Zhou et al., 2009, Katzev, 2003, Lane,

2005, Efthymiou et al. 2016, De Luca et al. 2016)
