3 1 1. Study background 3

4 Study background 1 Context: studies already performed in Asian Development Bank (ADB) loan proposed to finance transport projects in Tbilisi - Consortium with the French company Systra and the Georgian company Spectrum was selected to: - Review the feasibility studies of the projects in order to make them compliant with ADB international standards, - Include the projects into a global and strategic sustainable roadmap for short, medium and long-term solutions. 4

5 Study background 1 Conclusions of the studies performed in Several projects engaged in Tbilisi and financed on ADB loan: - Extension of Metro Line 2: procurement in progress for the works - Gorgasali tunnel: preliminary design done - Tbilisi Rustavi highway: preliminary design done - Mtkvari bridge: design in progress - Conclusion of the strategic road map: - A new modern public transport offer shall be developed to keep the modal part of public transport 5

6 Study background 1 New study performed in The French Government is financing a new study for Tbilisi City Hall aiming at: - Develop a multimodal transportation model - Propose a long term LRT network - Perform the preliminary design of the 1 st LRT line - The French company SYSTRA is involved in this project, helped by 2 Georgian companies - IPM, in charge of the household survey - Spectrum -Study began in December 2010 and shall be completed by December

7 LRT Study: main steps 1 1 st phase: (till June 2011) - Household survey, to have a clear and accurate vision of transportation habits in Tbilisi - Fieldwork already performed - Database cleaning and analyzing in progress - Multimodal transportation model: forecast future needs - Creation of the model (in progress) - Training of City Hall transportation team (in progress) - Proposition of a long term LRT network 2 nd phase: (June 2011 December 2011) - Preliminary design of the 1 st tramway line - Preparation of the relevant documents for a Design and Built Contract with multilateral financing: Cost Benefit Analysis, Initial Environmental Evaluation, Financial analysis 7

8 2 2. Household survey: preliminary results 8

9 Purpose of the survey 2 Very few data exists about transportation demand in Tbilisi, It is required to perform surveys at household houses to understand Tbilisi inhabitants current and future needs, Such surveys were never performed before in Tbilisi, Collecting data about transportation demand is essential to understand transportation-related issues and to propose relevant coordinated and sustainable projects corresponding to the inhabitants current and future short, medium and long-term needs. 9

10 Methodology of the survey 2 A transport zoning has been designed for the survey; it allows recording precisely the origin and destination of trips (all results are anonymous) 10

11 Preliminary results of Household Surveys 2 Motorized mobility and Age - Average motorized mobility in Tbilissi = 1.02 trips per day and per person. - The motorized mobility varies with the age of travelers. Children and old people have a lower mobility 11

12 Preliminary results of Household Surveys 2 Hourly Distribution of trips for a work day : - The morning peak hour is 8 am-9 am, representing almost 14% of the daily demand - Two minor peak hour in the afternoon : 2 pm- 3pm and 6 pm 7 pm 12

13 Preliminary results of Household Surveys 2 Car ownership: vehicule per household in average - Average age of private vehicles is around 15 years 13

14 Preliminary results of Household Surveys 2 Motive of trips at the morning peak period (8h-10h): 14

15 Preliminary results of Household Surveys 2 Market share of motorized modes : - Around 75% of motorized trips are performed using a Public Transport Mode - In Public Transport modes, the transfer rate is

16 Preliminary results of Household Surveys 2 Opinion - Evolution of transport conditions in Tbilisi : Public Transport Parking Condition Road Traffic 16

17 3 3. Development of a multimodal transportation model 17

18 Principles of the model 3 Multimodal 4 steps transportation model Based on the current situation in Tbilisi, to predict the forecast traffic, in function of the future transport demand Model developed under Visum Software 18

19 Inputs of the model: current transport offer 3 Current bus network in Tbilisi (Visum software) 19

20 Inputs of the model: the household survey 3 Important transportation-related data such as mobility, motorized mobility depending on income, age, occupation, trip motive, motorization Detailed O/D matrix for 300 zones in the city of Tbilisi Calibration of a detailed transportation model using internationally recognized software First step of a global study to define and evaluate in detail several transportation projects including the implementation of a Light Rail System in Tbilisi 20

21 Expected results 3 - Socio-economic projection at short, medium and long term taking into account land-use projects, - Test of proposed transportation projects (road, LRT projects, bus lines restructuration ) & reliable results, - Update of the model every two years. 21

22 Training of the Municipality 3 - Tbilisi City Hall is purchasing a specific software to have its own transportation model - Training program for Municipality staff so that they can use the model - 3 people of the Transport Department of Tbilisi City Hall able to use the software and the transportation model - Ability to test new transportation projects on a daily basis: new bus routes, new road infrastructures, etc.. 22

23 4 4. Development of a LRT network in Tbilisi 23

24 Stakes and challenges for the new LRT network 4 Main stakes for Tbilisi s sustainable development: - Anticipate the growth of the motorization rate due to the economic development - Anticipate the growth in mobility due to the economic development - Keep the current modal split by reinforcing quality and attractiveness of public transport and promoting Transit-Oriented Development (TOD) & promote intermodal passenger transport - Anticipate the new urban projects (housing and business centers) in order to propose projects suitable to future mobility needs. Total trips Car trips Public Transport trips 24

25 Principles of the new LRT network 4 Need for additional structuring Public transport network - Many areas not served by the Metro or a heavy PT system - Strong demand on some corridors served by many bus lines - Rationale for consolidating the demand into a LRT system with a high quality of service - Transforming the current O/D system into a corridor system with feeding lines - LRT lines are built in all modern cities - Municipality of Tbilisi showed a great interest in the project 25

28 Main traffic flows 4 28

29 Main bus corridors 4 29

30 Preliminary concept for the new LRT network 4 - Develop LRT lines on main bus corridors. For example Delisi Chachavadze Rustaveli - Promote the new urban development on Georgian Railways properties by developing a modern LRT line - Enforce the connections between both banks of River Mtkvari - Serve populous districts currently isolated from the rest of the City: Digomi, Didi Digomi, Gldani, etc. 30

32 Tramways as a leverage for urban requalification 5 Urban context Urban planning Technical constraints Urban integration Streets, intersections, parking Soft modes of transport Modal interchange TRAMWAY IN SEGREGATED RIGHT OF WAY Modern, Attractive, In harmony with its environment 32

33 Urban integration : topics to be studied 5 Green area constraints Crossing reshaping Road capacity reduction Platform integration Curve integration Systra study on Clemont-Ferrand Line 2 33

34 Urban integration : topics to be studied 5 Priority at crossings T3 Tramway - Paris Crossings functionning and design Buenos Aires study for a tramway line

35 Segregated right of way 5 LEVELS OF TRANSIT SEGREGATION Mixed traffic (buses) Partially segregated right of way, physically separated (tramway, BRT) or not (buses) Fully segregated right of way (metros) SEGREGATION PROVIDES A CONTROLLED ENVIRONMENT... No traffic to compete with Usually combined with priority at intersections FOR THE BENEFIT OF ALL Higher frequency of service Journey time savings Higher reliability and security Greater attractiveness and potential revenues Orléans (Systra) 35
