Future Cities project intends to contribute to …

• Identify critical areas• Air pollution• Noise pollution • Urban heat islands• …

• Real-time monitoring • Events • Atmospheric conditions• Pollution levels• Automatic detection of abnormal

situations• Persons • Vehicles• Excessive pollution levels

• Evaluate the impact of urban projects or interventions• Ex-ante evaluation• Post-evaluation procedure • As example:• Changes in traffic and related

alterations regarding noise and air pollution levels; and consequent response from the public

• Changes due to urban interventions in public spaces, regarding urban heat island effect

• Analysis of the impact derived from municipal policies regarding noise from places from entertainment

Future Cities project intends to contribute to …

• Research, using the city of Porto as a “living lab”• previously mentioned…• Wireless communication• Patterns recognition and data

analysis

• Pointed out henceforward…• Transports• Environment• Urban areas & energy efficiency• Urban planning.

UrbanSense PlatformIs a network of sensors that, apart

from the previously mentioned technological objectives, was designed to be the basic infrastructure of

data collection intended

This sensors’ network will allow to get relevant information for the research domains in which this

team intends to develop its knowledge.

UrbanSense Platform

• Will allow to proceed and extend current lines of research in several scientific domains

• Highlights the importance of multidisciplinary research and… a multidisciplinary team

• Will allow better knowledge of “real” urban conditions, considering the parameters to be monitored

Air pollution

Municipal strategies

Urban areas & energy efficiencyUrban interventions in public spaces

Urban climate and (sustainable) buildings

6

Transports & mobility• Public transportation network• Test some indicators to assess the quality of the network• Analyse the quality of the network

• Public transportation network and Drivers behaviour• Analyse the events and/or conditions that potentiate stress along the network• Analyse the influence of stress effect on driving patterns along the network

• Pedestrian movements• Analyse patterns and tendencies• Analyse the cross influence of factors regarding the motivation to walk• Analyse pedestrian movements and perceptions as users of the city

Porto as “living lab”


• Public transports• Pedestrian movements

“Urban” environment• Noise & Air pollution• Municipal strategies

Urban areas & energy efficiency

• Urban interventions in public spaces• Urban climate and (sustainable)

buildings

“Urban” Environment• Noise and Air pollution• Monitor the quality of the environment• Test some indicators for the quality of the environment gathering those pollutants• Test the accuracy of models • Test the possibility of using several forms of monitoring and estimate the referring errors• Analyse the influence of urban interventions on the propagation of pollutants

• Noise annoyance and quality of life• Analyse the perception of discomfort by the users (perceptions of quality of life)• Analyse the perception of discomfort on the part of neighbours of noisy activities (for example,

bars and clubs or discos or even large social and cultural events)







buildings

buildingsUrban areas & Energy efficiency• Urban interventions in public spaces• Characterize the urban micro-climate conditions, particularly, in public spaces• Monitor the use of public spaces before and after urban interventions (when possible)• Investigate the different patterns of use of public spaces• Some indicators for the quality of the urban environment regarding presence or absence of

green areas, climatic conditions, characteristics of the materials • Monitor the effects of interventions in urban areas in terms of hygrothermal comfort and public

appreciation• Monitor the use of the public space considering the quality of the urban environment and it’s

impact on pedestrians (e.g. fear of crime perceptions elicited by graffiti and “broken windows” theory)

buildingsUrban areas & Energy efficiency• Urban climate and (sustainable) buildings• Analyse the influence of urban form on wind propagation and sun exposure• Characterize the urban micro-climate conditions• Test the accuracy of urban climatology and bioclimatic design models• Analyse the relevance of using more realistic data in simulations of the thermal behavior of

buildings in urban areas, in terms of energy efficiency• Evaluate the significance of having more realistic data for an adequate design and choice of

solutions regarding energy efficiency, not only in buildings but also in public spaces

UrbanSense Platform: Use Cases

Some anticipated challenges

11

Ex: challenge 1

Transports

“Urban” environment


Changes in traffic schemes or traffic movements(volume, speed, pavement, …)

Changes in environmental noise & air pollutants concentration… …in a given area

But, what happens elsewhere?

How does urban form interfere with air pollutants dispersion?And with noise propagation?

How does it interfere with transportation policies?

12

Ex: challenge 2

Transports



How can spatial planning contribute or prevent annoyance?Are activities properly located, in terms of use conflict?

… in terms of public transportation?

How do people access those activities?Public Transportation? Private vehicles?

Are there parking facilities nearby?

Municipal policies regarding noise from permanent activities(the problem arises from the activity or from the gathering outdoors?)

13

Ex: challenge 3

Transports



Identify areas with “problems” and program interventionsNew conditions for public spaces (ex.: pedestrian zones, green

areas)

Is it possible to deviate the traffic? Is it possible to impose a modal switch for a less pollutant form of transportation?

Is it possible to reduce the number of vehicles in circulation, by reducing the needs of transportation?

Air pollutants monitoring and meteorological conditions monitoring

O3, PM10, …

N.º persons, N.º vehicles, speed, T, RH, Wspeed, Wdirection, …

14

Ex: challenge 4

Transports



Are there any changes in the traffic scheme? New pedestrian areas? New public transportation routes?

Changes in environmental noise & air pollutants concentration… …in a given area

But, what happens elsewhere?

Urban renewal interventions

15

Ex: challenge 5

Transports



Does new roads influence the micro-climate conditions?How should this issue be addressed when planning a new

development?

Better knowledge of the micro-climate conditionsRealistic input values for models

Monitoring of the environmental conditions

Need for urban renewal interventions in buildings with more concern in terms of energy efficiency

demand for…
