3rd International Scientific and Professional Conference CORRIDOR 10 - a sustainable way of integrations CONCEPTION OF TRAIN OPERATION TECHNOLOGY ON LJUBLJANA RAILWAY STATION DURING EXECUTION OF CONSTRUCTION WORKS SUPPORTED BY RAILSYS ENGINEERING SOFTWARE Damijan Žagavec, Prometni institut Ljubljana d.o.o, Ljubljana, Slovenia Primož Kranjec, Prometni institut Ljubljana d.o.o, Ljubljana, Slovenia Klemen Ponikvar,Prometni institut Ljubljana d.o.o, Ljubljana, Slovenia Abstract: The planned construction activities at the Ljubljana station will bring about traffic disruption (e.g. train delays) on the entire railway network. A well-selected and planned construction technology and according traffic operation technology conception during the construction works at the Ljubljana station is essential for control and limitation of traffic disruption. Major construction works are planned at the Ljubljana station, which will increase station and traffic flow capacities and allow implementation of supplementary passenger services at the station area (shopping mall). The works will be phase-run, each putting some restriction of exploitation of available station transport infrastructure; therefore it is necessary to conceive a train operation phase-wise. The paper presents a methodological approach to the train operation conception and its implementation on a selected case phase. Methodology describes spatial and technical limitations to be considered as well as procedure for elaboration of train operation microsimulations implemented in Railsys engineering software. The results show resolving of delays, conflicts between the train paths and track occupancy during the construction works. Key words: transport, railway traffic, train operation technology during construction works, traffic technology, railway station, RailSys, simulation, resolving of conflicts ZASNOVA TEHNOLOGIJE ODVIJANJA PROMETA NA ŽELEZNIŠKI POSTAJI LJUBLJANA V ČASU IZVAJANJA GRADBENIH DEL S PODPORO PROGRAMSKEGA ORODJA RAILSYS Povzetek: Načrtovani gradbeni posegi na postaji Ljubljana bodo povzročali motnje v prometu in širitev motenj (npr. zamude vlakov) na celotno železniško omrežje. Dobro načrtovana in izbrana gradbena tehnologija in ustrezna zasnova tehnologije odvijanja prometa vlakov v času gradbenih del na postaji Ljubljana je ključnega pomena za nadzor in omejevanje motenj v prometu. Na postaji Ljubljana se načrtujejo večja gradbena dela, s katerimi se bodo povečale postajne kapacitete ter pretočnost postaje, hkrati pa se bodo na postajnem območju uvedle dodatne dejavnosti za potnike (večji nakupovalni center). Predvidena dela bodo potekala v več fazah, ki bodo različno omejevale postajno prometno infrastrukturo, zato je potrebno zasnovati odvijanje prometa vlakov za vsako posamezno fazo. V članku je predstavljen metodološki pristop k zasnovi odvijanja prometa vlakov za izbrano fazo nadgradnje postaje Ljubljana, pri čemer so opisane prostorsko-tehnične omejitve, ki jih je potrebno upoštevati, ter postopek za izdelavo mikrosimulacije odvijanja prometa vlakov, ki je izdelan s programskim orodjem RailSys. Predstavljeni rezultati mikrosimuacije kažejo reševanje zamud, konfliktnih situacij med voznimi potmi in tirno zasedenost v času gradbenih del. Ključne besede: promet, železniški promet, tehnologija prometa v času izvajanja del, železniška postaja, RailSys, simulacija, razreševanje konfliktnih situacij. Belgrade, 2012 209
3rd International Scientific and Professional Conference CORRIDOR 10 - a sustainable way of integrations 1. INTRODUCTION Ljubljana railway station is located at the crossing of X. and V. Pan-European corridors passing through the territory of the Republic of Slovenia. All railway lines linking North, South, East and West of Slovenia pass through the Ljubljana station. Disruptions of traffic ensuing from a construction work at the Ljubljana station have impact on traffic flow on the entire Slovenian railway network and beyond. Additionally, disruptions affect the capacity of corridors meeting at the node (station). The planned construction activities at the Ljubljana station will bring about traffic disruption (e.g. train delays) on the entire railway network. A well-selected and planned construction technology and according traffic operation technology conception during the construction works at the Ljubljana station is essential for control and limitation of traffic disruption. Major construction works are planned at the Ljubljana station, which will increase station and traffic flow capacities and allow implementation of supplementary passenger services at the station area (shopping mall). The works will be phase-run, each putting some restriction of exploitation of available station transport infrastructure; therefore it is necessary to conceive a train operation phase-wise. Conception of train operations during the infrastructure possessions or planned slow runs is generally supported by several software tools. RailSys is one of them that excelled in several notable transport studies. The tool is comprised of several modules and functions. A micro-simulation module that we will discuss in the paper allows design and simulation-tests of train operation during restrictions entailed by planned possessions or downtime in specific infrastructure elements in order to provide optimal train operations in terms of set criteria. The results show level of resolving of delays and conflicts between the train paths as well as optimal track occupancy during the construction works. 2. ELABORATE ON RAILWAY TRAFFIC OPERATIONS DURING CONSTRUCTION WORKS Construction works on railway infrastructure under operation impacts change of regular trains’ operation. Design of trains’ operation is elaborated in the “Elaborate on railway traffic operations during constructions works” Contents of this elaborate are governed by Slovenian legislation: - technical and organisational measures, - costs induced by delays of passenger and freight trains, - costs of alternative transportation, - costs of organisation of infrastructure possessions, - costs of additional man-power requirements, - other costs. All indicated and required information can very effectively and precisely be produced using RailSys simulation software as described in the following. “Elaborate on railway traffic operations during constructions works” is an integral part of design and technical documentation that is required for acquisition of building permit. 3. RAILSYS – TRAIN OPERATION SIMULATION SOFTWARE TOOL 3.1 About RailSys software RailSys software provides integrated management of timetable paths and infrastructure data for the entire planning and operations process. RailSys software has the following system components: Belgrade, 2012 210
