Smart City Project

Traffic and Parking Management in

Bergamo

Università degli Studi di Bergamo

Sustainable Renovation in the

Upper city

2 Problem areas

Paolo Pesenti

Italy is the country with the highest numebr of cars per person (0.6) excluding Luxemburg and this condition inevitably create problems

. Traffic jams

. Pollution

. Waste of time

. Stressed citizens

. Productivity reduction

. “External costs”

. Long cruising for parking


Traffic negative effects

In Bergamo there is an extensive use of car because the alternatives are unattractive

Public transports and cycling do not receive the attention they should

deserve


Bergamo situation

Even if according to some surveys (ISFORT) citizens will be willing to use public transports for the same travel time

The Bergamo’s situation is not a negative exception in Italy, but it is the common “state of art” in all the country. Italy is in backwardness conditions respect to the north European countries in terms of efficient and eco-friendly transports.


Bergamo situation

poor Government investments

No innovative and sustainable solutions for transports

Car is an hardly replaceable key element of our city

! Increasing traffic

To solve this problem there are 2 solutions: the development of alternative and efficient mean of transports (private or public) or a proper implementation of a traffic management system


Two ways to solve the problem

Alternative and efficient means

of trasport

Traffic management

system

In dense urban areas, traditional construction of new capacity is cost-prohibitive and often physically impossible


Traffic Management

The current crisis of mobility can be solved with efficient urban planning and new technologies applied to traffic management

Bergamo has no a lot of opportunities to increase his capacity and physical infrastructures


Bergamo traffic management

Long queue and paralyzed traffic in Bergamo and the surrounded area during work days (Bergamo, Milan, Brescia)

Poor system of traffic management : . Traffic data from existing solutions are highly inaccurate.. No vehicle detection monitors installed. Monitoring traffic flow from closed circuit television videos (unreliable and time-consuming task)

The city of Bergamo needs a smart solution that allow inhabitants to know in real time the evolution of the traffic, as proposed in “ The City to Come” (Nabian, Ratti).


What does Bergamo need ?

Intelligente use of infrastructures

Real time info

Citizens distributed and better decisions

Prediction from hystorical data

Advantages for inhabitants and

authorities

. ICT technologies such as microcontrollers and sensor

. Informaton received on Pc or apps for smartphones

. inhabitants can be active participants, enhancing the quality of the traffic management

Between 8% and 74% of traffic in congested downtown areas is caused by people cruising for parking, spending between 3.5 and 14 minutes searching for a space each time they park.


Parking

Bergamo limits:. A lot of parking in narrow streets.. No wide parking spaces. No uniforme management of private and public parking areasSmart

meters and

parking sensors

Real time info provided to drivers (app) on avaiable

parkings

Advantage for drivers

and officials

SOLUTION


Examples

. Very interesting management traffic system in : Stockholm (Sweden) and Bucheon City (South Korea) ;. IBM has developed and is implementing new traffic prediction tools;. Interesting example of smart parking systems are in Los Angeles.


Sustainable renovationOver the last 50 years In Italy the majority of the renovations of ancient building have been focused on the architectural and structural aspects

•Diffused environmental issues

•Sustainability ancient of buildings

•Smart City


Bergamo Upper city : Città Alta

.Upper city surrounded by Venetian walls built in 17 th century;. Old Square;.Cathedral;San Vigilio Castle….

but also :

. 3100 inhabitants;

. Residential properties;

. Restaurants

. Shops


Sustainable renovation of historical buildings in the Upper CityIn this context the challenge is to adapt the new solutions of green energy to the ancient building without ruining their typical characteristics and beauty

Città Alta residential emissions

Sustainable Energy Action Plan, 2010

The data from the SEAP 2010 (Sustainable Energy Action Plan) demonstrate that the residential buildings in the upper city have one of the highest value of carbon emissions per person, equal to 8.28.


Città Alta emissions In Città Alta the majority of the houses and buildings used for commercial activities have the lowest levels of energy certification (F and G).

The energy certification is a procedure of evaluation established by the European Community in 2002 that helps to classify the level of consumed energy by a building. The highest performance is classified with A, while the lowest with G. The energy class is determined considering the level of kWh/(m2a).

Low energy certification of houses


Città Alta emissions In Città Alta there are also a lot of churches (as the cathedral) and historical buildings used for tourism and cultural purposes (for instance museums).

These buldings are normally heated

High energy consumption

Conflict between preservation

and conservation measures


Weak strategiesThe City of Bergamo has already developed a series of strategies of energy conservation in the construction sector.

The objective of SEAP is to reduce the emission of carbon dioxide of 20% by 2020.

BUT… these activities focused mainly on the procedures for the construction of new building and nowadays a clear plan for sustainable renovationsdoes not exist.


What does Bergamo need ?

Green

solution

sBeauty of historical heritage

Eco-friendly buildings

Design and

aesthetical

solutions

Investments in new

technologies

Consistent

Urban Planning

Balance


ExamplesThe applied solutions have to be customized for the different buildings and needs, in order to integrate them with the landscape and don’t be aesthetically invasive

Aula Nervi, Rome


Questions

. How can (historic) buildings be conserved and enhanced through energy-efficient measures?

. Which strategies can be taken to adapt (historic) buildings to new functions and user demands?

. Which options realize an optimum building quality with the least possible intervention?
