University of Zagreb Faculty of Transport and Traffic Sciences Zagreb, 10 October 2013

Presentation overview

 Measure objectives  Implementation process  Measure outcomes  Lessions learned from the process CIVITAS-ELAN presentation, Miroslav Vujic

Mesure objectives

 two key objectives: 

improvement of mobility

for all vehicles by giving priority at intersections to public transport vehicles 

Improvement of public transport system quality

in general  What was done?

 Relevant data collected  Micro and macro simulation models produced  Implementation finished  Evaluation of implementation CIVITAS-ELAN presentation, Miroslav Vujic

Mesure objectives – cont.

 demonstration corridor: • • 3.2km long Savska street Connects the historic City centre (north) with south (entrance) of the City  Traffic situation: • • bi-directional traffic personal vehicles and PT vehicles are operating in one (same) level CIVITAS-ELAN presentation, Miroslav Vujic

• • •

Implementation process – Task No.1

Define PT performance indicators • • • • •

PT operation time

Dwell time

Intersection delay

Speed per segment Operational speed Develop microsimulation model of existing traffic situation for the entire corridor • • PTV VISSIM software package Build traffic network • Number and width of lanes • Signal logic, etc.

Calibrate developed model according to existing traffic situation CIVITAS-ELAN presentation, Miroslav Vujic

• • •

Implementation process – Task No.2

Develop and define transit priority algorithms for every signalized intersection on the corridor • Active priority techniques – detection of vehicles' presence Implement defined algorithms in simulation model • PTV VISVAP module was used for defining and implementing priority algorithms Gather simulation results and evaluate benefits of transit priority implementation • Evaluation based on defined PT performance indicators CIVITAS-ELAN presentation, Miroslav Vujic

Implementation process – Task No.3

 Implementation of PT priority techniques on 3 intersections on the corridor • • • Hebrangova Street Dezeliceva Street Varsavska Street • • Priority technique: • Early green is enabled if PT vehicle is detected (just northbound) • Detection zone: 150m before the intersection Technical solutions: • • Commercial VECOM from Peek Traffic Experimental RFID solution CIVITAS-ELAN presentation, Miroslav Vujic

Measure outcomes

• Simulation model results: • PT priority defined and implemented in simulation on the whole corridor & all intersections • Main performance indicator: • average PT operation time 

8,85%

• Not satisfied?!

• Observing time perspective: •

Before:

20,37min •

After:

18,42min

2,28min of

benefit – one PT line per one hour!

Measure outcomes – cont.

Objectives

Increase PT avg. speed Decrease avg. running time Decrease intersection delay Decrease no. of vehicles

Achieved

6,9% 7,3% 17,84% 1,89% CIVITAS-ELAN presentation, Miroslav Vujic

Lessions learned from the process

 teamwork is essential!

• project leader must define schedules, boundaries and tasks for every researcher and involved partners!

 importance of the input traffic data • traffic volumes, queue length, etc. needed for development of simulation model • traffic modeling is crucial  better communication and cooperation between partners CIVITAS-ELAN presentation, Miroslav Vujic
