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.

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?

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

| Operation

| Rolling stock

| Systems

| Energy

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 7

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 8

STATIONS

Methodology

| Analyze the urban integration of 7 different concepts for stations

| Perform dynamic flows simulations

CODATU XVII – High capacity tramway November 2017 9

STATIONS EXAMPLE – THREE PLATFORMS

Boarding

passengers

Alighting

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

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…)

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.

HIGH CAPACITY TRAM CONCEPT

Compared to standard tram systems:

| Capacity x4 (up to 12 000 pphpd)

| CAPEX x2 (20 M€/km in developing countries)

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)

| Bus networks

As per 12th 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

| Metro (from 1984 in Kolkata)

CODATU XVII – High capacity tramway November 2017 15

THE RIGHT LRT FOR INDIA ?

Conditions are different than in Europe

| Higher demand level

| ROW limited

A specific LRT system has to be designed for Indian context

| Congested roads, mixed traffic

| Jay walking common

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)
