People Flow Campus Pilot – Smart Otaniemi (European Regional Development Fund 2021-2

The goal of the People Flow project is to do measuring and modelling of people flows within the Otaniemi campus region for better campus planning and optimized use of campus facilities. Indoor traffic is measured by using Wifi-data. Outdoor people flows are covered with various sensors including cameras, radars and lidars. Various data analysis, modelling and simulation will be applied through open API:s. The results will be available on a campus mobility dashboard.

The People Flow activity is part of the ERDF funded KETO-project “Implementation pathway for environments that accelerate sustainable growth” in co-operation with City of Espoo, VTT and Omnia. The project is part of the Smart Otaniemi 2.0 initiative.

Smart Junction – Jätkäsaari Mobility Lab, Helsinki (2019- )

Smart Junction project is carried out in co-operation between Aalto University, City of Helsinki, Port of Helsinki and Conveqs Oy. Also, several other parties are involved in the project. The test area provided by Helsinki is called the Mobility Lab Helsinki. New type of traffic sensors have been installed into 6 critical junctions from the harbour to the motorway. Each junction is equipped with sensor stations consisting of camera, radar and edge computing unit. Each sensor station is pointing upstream of one approach of the junction. Also, lidar installation is under testing for covering the pedestrian and bicycles in the intersection area. Data is also collected from the traffic signal controllers (signal status) and from the public transport API of Helsinki Regional Transport (HRT).

The data from all the sources is collected into an open data platform that connects the data streams to open interfaces (API).  The data from various sources is combined into so called real-time digital twin that represents the overall traffic situation in a machine-readable form. The digital twin of traffic can be used to traffic analysis/prediction, transport plannig, signal control optimization and infra support to connected and/or automated vehicles.

Last Mile – Perille Asti (EU Regional Funding 2017-19)

The project aims to improve the mobility of the residents, employees, customers and international visitors in Helsinki metropolitan area, complementing the existing transport system. The project aims to find new market-driven, intelligent mobility solutions and services for the companies in travel industry. Companies can include new mobility solutions as part of their own service offering. Also, residents, employees and other business in the region can take advantage of the developed services.

The new mobility services are co-created and developed in public-private partnership in Helsinki (Jätkäsaari), Espoo (Nuuksio) and Vantaa (Aviapolis and airport area related travelling). Some of the services will be piloted in the target areas. The target group of the project consists of companies that develop and implement mobility services for enterprises and end-users. Examples of these solutions are shared modes of transport, a new type of bike rental concepts, on-demand transport, regional mobility services and last mile solutions.

The TrafficSense mobile application by Aalto University was applied in measurement of mobility behavior around the Jätkäsaari region. A “mobility gap” was found indicating that the sustainable modes like walking and biking were not fully used even when they offered a competitive travel time.

TrafficSense – Energy Efficient Traffic with Crowdsensing
(Aalto Energy Efficiency Funding, 2013-2017)

TrafficSense is a multi-disciplinary project with other research groups in Aalto funded by the Aalto Energy Efficiency Program (AEF). The aim is to promote more energy efficient and green modes of transport through personal mobility management assistant (PMMA) based on crowdsensing of traveling behavior. The TrafficSense system is able to automatically detect the basic parameters of individual trips including the mode of transport and the public transport services used. Based on this data the system learns the mobility patterns and is able to predict next trip to done. Based on prediction the system look for potential problems or opportunities and suggest alternatives which are more energy efficient. TrafficSense approach is one of the necessary steps toward mobility as a service (MaaS). Read more

Real-time situation awareness combined with multi-agent control provides the framework (the FUSICO-software). Most recently multi-objective optimization of traffic signals is studied in co-operation with KTH (Royal Institute of Technology). Read more

Light Energy – Efficient and Safe Traffic Environments
(Aalto Energy Efficiency Funding, 2012-2016)

The Light Energy – Efficient and Safe Traffic Environments project improves the energy efficiency of transport environments and outdoor lighting while maintaining a good level of road safety and taking into account the needs of road users. The project studies the optimal realization of lighting and develops smart control of lighting by considering the visibility and safety of road users, the traffic situation, and environmental and economic factors.

The specific target of Transportation Engineering is to study the effects of street lighting to traffic safety and develop an energy efficient and safe traffic responsive street lighting control method.

Microscopic simulation of pedestrian flows (2011-2016)

This study investigates the effects of attractions to pedestrian flows. The aim is to model interactions between pedestrians and attractions including shopping displays and museum exhibits. In reality, such attractive interactions may lead to impulse stop behavior; pedestrians stop walking to destinations and join the attractions. The simulations indicate clear phases of the pedestrian flow, namely free flow, agglomerate state and competitive state. The results can be applied to the planning of public spaces. The research work was partly funded by the MIDE-institute of the Aalto University though the 4D-space project.

Aalto ITS Initiative (Aalto Special funding 2011-2012)
