HUTSIM has been developed by Helsinki University of Technology / Laboratory
of Transportation engineering since 1989. During this time several co-operation
projects with domestic and foreign country partners have been succesfully
carried out. This co-operation has been a great support of HUTSIM development
and these projects have had a substantially influence on HUTSIM development.
HUTSIM has also been used as tool for several research projects of which
some are listed here.
- PROMPT - Priority and Informatics for Public Transport (DRIVE-II)
In co-operation with TFK in 1992-1994, HUTSIM was used for off-line
evaluation of SPOT Urban Traccic Control System of Arena test site in Gothenburg,
Sweden. Among other things A serial mode communication interface to the
SPOT-system was built into HUTSIM to allow HUTSIM to feed detector and
public forecast messages and to read signal stage messages from the SPOT-UTC.
- SOS-II - Self Optimising Signal Control
A new type of optimising signal control strategy was to be developed
in Sweden in order to combines the good sides of stage oriented mathematical
optimisation and flexible signal group control. HUTSIM was used by TFK
for off-line evaluation of the SOS-II control system during 1993-1995.
HUTSIM/ELC2 interface was enhanced with serial communication to SOS-unit,
that obtained detector data from HUTSIM and submitted green stop orders
to ELC-controller via HUTSIM.
- GUTS - General Urban Traffic Simulator
For several years during nineties HUTSIM has been gradually developed
from traffic signal simulation towards general purpose urban traffic simulation.
Important part of this work is done in co-operation with TFK in prelimary
usage of HUTSIM in motorway simulations during 1994-1996.
- TPMA - Traffic Performance on Major Arterials
New motorway simulator is to be developed based on principles of HUTSIM.
This work is to be done in the new competence center founded in Royal Institute
of Technology (KTH) ,Sweden. In co-operation between HUT, KTH and VTI this
project is to be carried out during 1996-2000.
- Calibration Research Projects
Several research projects have been carried out in order to calibrate
the micro parameters of HUTSIM model. In these projects carried out by
HUT during 1991-1995 large aount of field measurements were made to obtain
proper values of vehicle acceleration/deceleration rates, car-following
and yielding gaps, curve speeds etc. Simulated macro measures like average
saturation flows, delays, queues and stops have been compared with the
- FUSICO - FUzzy SIgnal COntrol
Finnish Academy has funded a three year project (1996-1998) to investigate
the prospects of fuzzy signal control in isolated intersections and to
develop a fuzzy signal controller for field trials. The basic idea is to
model a human way of evaluation of traffic situations and to determine
the control action i.e to imitate the constable on point-dut.
- HUTSIM/ DIME - Distributed Simulation
The collaboration with the Nottingham Trent University, Real-time telemetry
systems group started already in 1994, however more active phase is scheduled
during research visit in autumn 1997 and spring 1998. In the first phase
HUTSIM is attached with the Distributed shared Memory communication facility
(DIME). This will allow several new applications like for example to run
HUTSIM models to be run in several computers thus resolving the problem
of limited computing power. Using HUTSIM as on-line visualisation/monitoring
tool with the SCOOT-UTC is another example of the possible applications
of this framework.
- INCOME - INtegration of signal COntrol with other MEasures
The effects of dynamic route guidance is to be evaluated in INCOME-project
in co-operation with TFK in 1997-1998. HUTSIM model will be upgraded with
route choice modelling based on the link travel time information. This
model will allow drivers to either obey the route guidance or the defined
- HESAID - Help to Energy Saving with Alternative Infrastructural
Design and Traffic Control Systems
This SAVE 2-project project will deal the possibilities of quantifying
the energy saving aspects of intersection design and advanced traffic signal
control systems on the micro level by recently developed methods and models
for comparison of the effects of different intersection performances.
- MOBILE-217T, Estimation of the Impact of Traffic Congestions on
The fluency of traffic has an decisive effect on the emissions and
the fuel consumption of traffic. The aim of this study has been to produce
information about the behaviour of vehicles in urban traffic and to study
the impacts of the traffic signal control on the energy consumption of
signalised intersections. The research methods used in this study were
videorecording from helicopter and microsimulation by the HUTSIM-simulation
- Saturation Flow Study 1994-95
New basic values for saturation flows of different lane types were
obtained by combination of field measurements and HUTSIM-simulations. The
new basic value of lane type A is chosen to be 1940 veh/hour.
