IS-practice Plan4all conference, Chateau Kozel, 4 Oct 2017 1
The Pilsen problem? Traffic …
IS-practice Plan4all conference, Chateau Kozel, 4 Oct 2017 2
… and multiple
road works
 Intense traffic in the rush hours
 No coordination of road works planning
-->Multiple overlapping road works
(different organisations involved)
 Citizens not well informed about road
closures
IS-practice Plan4all conference, Chateau Kozel, 4 Oct 2017 3
Situation in Pilsen
A year ago: first prototype (OTN)
IS-practice Plan4all conference, Chateau Kozel, 4 Oct 2017 4
Planned road
closure
Major detours
Amount of cars
per street segment
/ hour
IS-practice Plan4all conference, Chateau Kozel, 4 Oct 2017 5
Pilsen Smart City Policy
IS-practice Plan4all conference, Chateau Kozel, 4 Oct 2017 6
Development of a new web app
 Currently 10 major road works in the
city included in the traffic modelling
 Regular quarterly re-calculation to
reflect current situation
IS-practice Plan4all conference, Chateau Kozel, 4 Oct 2017 7
Major city roadworks included
 City divided in 180 ’traffic generators’ (urban
zones, office districts, shopping malls, industrial zones,
university campus, schools)
 Origin-destination matrix calculates the counts
of vehicles among all traffic generators in the city
 Vehicles amounts assigned to the road network
 Fastest route and the capacity of streets taken
into account
 Subsequent calibration by street measurements
(sensors and manual)
 Daily and hourly traffic volume coefficients
application
 Data published as WMS-t

Traffic Modelling Methodology
IS-practice Plan4all conference, Chateau Kozel, 4 Oct 2017 10
Dynamic Visualisation of Traffic
Traffic
animation
per hour
Date selection
Overview of
ongoing
roadworks
IS-practice Plan4all conference, Chateau Kozel, 4 Oct 2017 11
Road Segment and Road Work Details
Amount of cars per hour
Traffic intensity level
Roadwork details (scope,
duration, detour)
IS-practice Plan4all conference, Chateau Kozel, 4 Oct 2017 12
Traffic intensity levels
 Traffic intensity levels according to the
commonly used scale
 ‘Gantt-chart-like‘ overview of road works
IS-practice Plan4all conference, Chateau Kozel, 4 Oct 2017 13
Interactive Timeline
 A static traffic model of the city brought to
the public in an open, web-based,
interactive form
 Citizens receive regularly updated
information about the road works in the
city
 Prediction of traffic situation – this is what
Google, Waze and others do not have!
 City can better coordinate planned works
 Data available for further use in other
domains – e.g. marketing & advertising,
noise and emission calculation, real-estate
IS-practice Plan4all conference, Chateau Kozel, 4 Oct 2017 14
Benefits
 https://intenzitadopravy.plzen.eu/
 English version available at

Try it yourself!
 Title: Policy Development based on
Advanced Geospatial Data
Analytics and Visualisation
IS-practice Plan4all conference, Chateau Kozel, 4 Oct 2017 16
Next? PoliVisu Project
 Duration Nov 2017 – Oct 2020
 Financed under H2020
 15 partners from all over
Europe
 Solutions verified in three
pilots: Ghent, Pilsen, Paris
(Issy-les-Moulineaux)
 Automated traffic model
recalculation (close to real-time)
Using parallel cloud computing and
distributed server infrastructure (e.g.
AWS)
 Use of road sensor data and Waze data
for the traffic model improvement and
calibration
 Short–term (few hours) traffic
prediction based on current traffic

Editor's Notes

  1. Wireframes of the new GUI - Development April-June 2017
  2. Traffic volume calculation methodology The application predicts the traffic volume on a selected day and hour based on the traffic model of the city and currently ongoing roadworks. The calculated traffic volume is calibrated by the street measurements. The traffic model is based on a matrix that calculates the number of vehicles travelling between every two of approx. 180 'traffic generators' located in the city e.g.: urban zones, office districts, shopping malls, industrial zones, university campus, schools etc. The roadworks ongoing on the selected date are taken into account in the calculation as well. After the matrix calculation the counts of vehicles among all the traffic generators are portrayed on the road network, while the ideal (fastest) route together with the capacity of streets and crossroads is taken into account. The resulting traffic volume is subsequently calibrated by the street measurements of vehicles counts at selected locations. In order to display the traffic volume in the dynamic web application, the colour scheme of five colours (from green to red) is used to represent the traffic volume, matching the five traffic volume levels used by the Police (see the Legend). The figures displayed on the road segments represent the expected amount of vehicles on the street per hour. The web application consumes the data in the form of a WMS-t web map service (see specification, annex D).

  5. the close-to-real-time traffic model recalculation requires a significant computing power which has not been available until recently. However, the recent availability of distributed server infrastructure and parallel cloud computing technologies (e.g. the Amazon web services), and the research of the MapReduce programming model done by the PoliVisu team allows to perform such big data calculation in almost real-time which makes it usable for these web applications
