EGIS & LIGHT RAIL TRANSIT European leader in light rail engineering, Egis has made a vital contribution in the revival and modernization of the tramway. We take part to the success of iconic projects, often conducted under the constraints of tight budgets and schedules. 87 cities 30 in France 57 outside France Engineering project management of over 800 km of LRT lines CODATU XVII High capacity tramway November 2017 3
MODERN TRAM SYSTEMS Modern tram systems have significant advantages fast and reliable system at-grade infrastructure seamless urban integration reduced costs compared to a metro system But limited capacity compared to metros or BRT. How can we increase the tram system capacity while keeping its advantages? CODATU XVII High capacity tramway November 2017 4
HOW TO INCREASE ITS CAPACITY? Increased tram capacity, form a broad perspective it is easy: Increase rolling stock unit capacity Decrease headways Looking at details, it is a new concept that has to studied from various perspectives: Stations Systems Operation Energy Rolling stock CODATU XVII High capacity tramway November 2017 5
EGIS RESEARCH PROGRAM Egis has launched a research program aiming at studying these aspects in order to reach a capacity of at least 12 000 persons per hour per direction. This presentation will focus on Stations Traffic management CODATU XVII High capacity tramway November 2017 6
STATIONS Issues Stopping time (duration and reliability) Flows managements Emergency evacuation Access control and fraud deterrence Urban footprint CODATU XVII High capacity tramway November 2017 7
STATIONS Methodology Analyze the urban integration of 7 different concepts for stations Perform dynamic flows simulations CODATU XVII High capacity tramway November 2017 8
STATIONS EXAMPLE THREE PLATFORMS Alighting passengers Boarding passengers Segregated boarding and alighting flows No conflicts between passengers Reduced passenger boarding time This station can be implemented on one site of the road next to a pedestrian square to ease access Pedestrians can cross tram and cars separately CODATU XVII High capacity tramway November 2017 9
TRAFFIC MANAGEMENT Methodology Analysis of different junction configurations Dynamic modeling of trams and car movements Design and operating guidelines for tram junctions (minimum tram headway, restriction on car movements, tram speed ) CODATU XVII High capacity tramway November 2017 10
TRAFFIC MANAGEMENT Modeling shows that trams with double unit capacity and half-headways compared to standard tram systems (capacity x4) crossing of large junctions remains acceptable and generates few additional disruption on the tram system. The impact on traffic is comparable to standard tram systems due to specific mitigation measures such as left turn restrictions. CODATU XVII High capacity tramway November 2017 11
Commercial speed (km/h) HIGH CAPACITY TRAM CONCEPT Compared to standard tram systems: Capacity x4 (up to 12 000 pphpd) CAPEX x2 (20 M /km in developing countries) High Capacity Tram Heavy metro Light metro Capacity (pphpd) CODATU XVII High capacity tramway November 2017 12
WHERE IS THE CONCEPT SUITABLE? Favorable conditions for the high capacity tram concept Wide corridor (>15m) rather linear Single line, no overlapping of lines Acceptable junction density (> 300m) Commonly found in emerging countries Compared to other systems with similar capacity, the high capacity tram has better ability to integrate within dense urban areas.

INDIAN CONTEXT Historical predominant urban mass rapid transit in India Suburban Rail (from 1928 in Mumbai) Metro (from 1984 in Kolkata) Bus networks As per 12 th Five Year Plan (2012-2017) LRT should be provided in all cities with a population of million + As per 2013 census it represents 53 cities in India In larger cities, LRT could be part of citywide MRT network, as medium capacity feeder CODATU XVII High capacity tramway November 2017 14
THE RIGHT LRT FOR INDIA? Conditions are different than in Europe Higher demand level Congested roads, mixed traffic ROW limited Jay walking common A specific LRT system has to be designed for Indian context Different technologies : elevated sections, robust rolling stock A different social model : manned stations, priority for sustainable development, an inclusive transport system Harrapan urbanism (1 700 BC) CODATU XVII High capacity tramway November 2017 15
