Transport plans for capital city of Amaravathi: A critical appraisal and alternative options




1 Introduction

Amaravati, the proposed capital city of Andhra Pradesh, barring a few villages being developed on virgin lands, gives a good opportunity for developing well conceived urban transport system that could overcome plethora of problems that beset cities in India and globally. Government of Andhra Pradesh unveiled a Draft master plan prepared by Surbana International Consultants Pte Ltd and Jurong Consultants Pte Ltd, on behalf of a Governmental agency of Singapore.  The purpose of the article is to critically review proposed urban transport plan to bring out their strengths and weaknesses and suggest suitable modifications to develop a workable, equitable and efficient transport plan.

1.1  Review of the proposed transport plans

As in any normal city the system proposes hierarchy of roads consisting of national highways and expressways, arterial roads, sub arterial roads and collector roads and recommends road widths of 60, 50, 40 and 25 metres respectively. In addition the report also refers to local roads within neighbourhoods but the standards for these are left to the development guidelines and individual developers.
The proposed roads, except expressways and national highways, are planned to have cycle and pedestrian paths of around 1.8 meters (except 3 meters on one type of sub arterial road – which probably is a typo as no apparent reason is provided for this deviation).
In addition the system promises a public transport infrastructure and network and proposes a normal bus system to be run by state road transport corporation, a bus rapid transport system (BRTS) on arterial roads and a 147 kilometre rail based mass rapid transit system (MRTS) on an elevated corridor. The plan is silent on corridors on which bus transits would run but gives details of routes on which MRTS is to be run. It further refers to high speed rail (HSR) to be developed by Indian Railways and how it can connect Amaravati to Vijayawada and Chennai (Draft capital city master plan report - part 2, 2015).

1.2   Critique of the plan

A master plan should be providing a strategy to develop intra-city and intercity transport based on national urban transport policy (NUTP) which enunciates: i) encourage cycling and walking (Non motorised transport – NMT) ii) discourage car travel especially for daily commute and iii) encourage public transport. This should have guided the infrastructure development. As the plan is based on the experiences from Singapore and from consultancy organisations based in Singapore it is expected to draw heavily from Singaporean experience in urban transport is not reflected in the plan.
The plan gives a few infrastructure options but does not prioritise them. The plan also does not relate to the Indian urban transport context and how to influence it to the desired policy outcomes. While discussing the options for public transport the discussion was neither comprehensive nor based on data set as per the Indian context[1]. Master plan also does not dwell how different towns/cities would be connected and how the intercity traffic should be dealt in the new city.
The plan comes across as a medley of infrastructure options and not an integrated transport plan.

2  Policy propositions on NMT and Motorised Private travel

As enunciated in National Urban Transport Policy (NUTP), capital region should have policy such that NMT and public travel is encouraged and vehicle travel, mainly car travel, is discouraged. While issues related to public transport are discussed later, we dwell here on private travel and design of road infrastructure. 
First and foremost reason for restricting car travel and encouraging NMT would be the utilisation of road space. Lane capacity, measured as persons/vehicles per hour per direction per lane, in a typical 3.5 metre road is 19,000 persons, 14,000 cycles, and 2,000 cars for walking, cycling and car respectively (Botma and Papendrecht, 1991). Using average occupancy of cars in India  as 1.2 persons capacity for a car lane works out to 2400 (Badami, Tiwari and Mohan, 2004). Thus in terms of space utilisation a pedestrian requires one eighth space and cyclist one sixth space compared to a commuter by car. 
In addition in Indian context the socio-economic conditions are such that car use is limited compared to walking and cycling and this is vindicated by a study commissioned by Ministry of Urban Development. The study showed that in eight largest cities of India shares of walking, cycling and cars in total trips was between 19-38, 4-12, and 9-15 per cent respectively (Ministry of Urban Development, 2008). These shares are in a scenario where walking and cycling on road, in the absence of dedicated infrastructure, are considered unsafe and between them share the highest number of fatalities in road accidents.  
Keeping the foregoing road infrastructure in the Capital region should be planned such that movement of pedestrians and cyclists and their integration to public transport should be the central focus. This is detailed below. Motorised private travel should get less priority compared to NMT. There could be exceptions to such as movement of ambulances or movement of physically disabled etc.
Walkways and cycleways should be laid throughout the city and they should be barrier free. All crossings should be at grade for the pedestrians and cyclists changing the motorised vehicle paths if necessary. The paths should be so laid that as far as possible a cyclist and a pedestrian should be able to take the shortest path between any two points.
On all roads with width of 40 meters or more provision should be made for 3.5 meter wide walkways and cycleways in both directions. This will help in facilitating a bidirectional cycle and pedestrian movement on both sides of the road. The current provision of 1.8 meters is highly inadequate for bidirectional movement.
Certain expressways in the plan do not have the cycle and pedestrian ways. This should be revised and exclusive cycle and pedestrian pathways should be provided; either as a part of the main road or as a part of the service lane. On the distributor and collector roads, whose widths are 25 meters, pedestrian and cycle ways should be at least 2.5 meters each.
Extra space required can be accommodated by reducing the car lanes to 3 meter width from the current 3.5 meters except for bus lanes. If the extra space is not possible within the existing road geometry then the road can be widened to that extent or car lane widths reduced to 2.7 meters (9 feet) restricting the speeds. (Speck, 2014)
Detailed designs can be developed for these roads as part of the detailed design.
Equally important is the need to regulate car movement in the capital city region and experience from Singapore should be valuable. The measures to regulate should include the following:
Identify corridors and areas where congestion charges should be levied. In addition to area specific approach toll charge should be levied as per the level of traffic; higher traffic should entail higher toll charge. This would discourage peak hour traffic. Congestion pricing should become part of the city transport planning and not become a later thought out scheme.  
Similarly car ownership should be regulated. Vehicle regulation should be should be multilayered; distinguishing between different kinds of ownership. For example Singapore fixes an annual quota for vehicles which can be used without restrictions while it has another type of vehicle permit which can be used during off peak hours. In case of former a annual quota is fixed and people are decided through a competitive bidding.
Further details for implementing these can be worked out after discussing with various agencies.
The issue of two wheelers is not discussed separately as they share same infrastructure with cars but use them more efficiently. Hence no specific restrictions are envisaged immediately.

3   Public Transport by Rail and Road – Inter city and intra-city

As cities grow in size, as is the case with Amaravati, intra-city and intercity transport and their integration becomes important. For intra-city transport the plan considered three options – conventional bus, BRT and elevated rail system. For intercity transport the plan refers to the high speed rail system proposed by Indian Railways in its vision 2020 document and specifies a corridor for high speed rail. The plan does not refer to any other intercity transport system for the capital city.  In this section the proposed plan is critically scrutinised to show its inefficiency and also lack of understanding of contemporary transport systems in India and the areas around the Capital region. Alternate public transport plan is proposed which grows as the city grows, needs far fewer resources and symbiotically builds on the existing transport infrastructure.

3.1        Intra-city public transport systems: A critical appraisal and alternative options

The operational characteristics of an elevated metro system, a BRT system, and a surface rail system are presented in the Table below.
Table: Construction cost and capacity created for different public transport systems

Assumptions: All the figures are for peak performance of the system.
Elevated rail; A 6 coach train running at a frequency of 3 minutes
BRT: A 3 unit articulated bus running at a frequency of 45 seconds on a dedicated single line corridor.
Surface rail: A 16 coach train running at a frequency of 5 minutes.
Source: Compiled from Ravibabu and Phanisree (2014)
As seen from the above investment in surface rail system can create infrastructure capacity 20 times that of an elevated rail system and the BRT creates capacity 5 times of the elevated rail system. Thus for the same investment the 147 kilometre metro rail system planned for Amaravati city can be replaced with surface rail system of 1470 kilometers which would have a capacity of 2940 kilometer metro system.
As city of Amaravati is planned to be built from scratch on nearly virgin land it would be advisable not to build any elevated systems but to plan for surface rail and BRT corridors. Elevated corridors should only be considered where space is a major constraint and thus become unavoidable in already built areas. Hence, in Amaravati it is essential to plan for a surface rail system from the beginning and build elevated systems as critical links when they become inescapable. Building surface rail system also enables integration with the neighbouring rail systems. Next section brings out how integration with adjacent rail systems can be done to produce a robust intra-city and inter-city transport system.

3.2  Inter-city transport system; Need and strategy for rail connectivity

As per the master plan Amaravati city will be connected to other cities either by road or an high speed rail. As the pre-feasibility study of the high speed rail on the Chennai Vijayawada is still not commissioned, whether and when the high speed rail would be operational is highly speculative – and looking at the overall scenario of construction of high speed rail in India the system will not be built in the immediate future (next 10-20 years). Thus Amaravati would be the only city in India with a two million plus population without connectivity to the conventional rail system. This should be corrected if the city is to be planned as a green city.
In addition to the connection to the rail systems close by it would advisable to connect the existing towns to the new capital city to provide an avenue for affordable mass transport.
The table below gives towns and their distance from Thullur village – an important and central village in capital region.

Different rail routes in and around Thullur village along with the distances from the village to suggested junction points are given below:
·        Guntur – Nadikudi line – 24 - 27 km joining near Sattenapalle
·        Guntur - Dhone line by extending Sattenapalle spur by another 20 kms joining at Narsaraopet
·        Vijayawada - Hyderabad line –18 to 20 kms joining near Kondapalli
·        Vijayawada - Visakhapatnam line by extending Kondapalli spur by another 15 -17 kms joining at Ganavaram
·        Vijayawada - Guntur – 17 to 21 kms joining near Mangalagiri
·        Vijayawada ­- Chennai line – 6-15 kms – by extending Mangalagiri spur joining at pedavadlapudi or any other convenient station

Thus by providing a total rail length of around 250 to 275 kms the towns and rail lines in close vicinity would be connected to Amaravati capital city. As these connections are in addition to the proposed road and high speed connectivity they would provide a wide variety of transport options to come to Amaravati city.

3.3  Integrating inter-city and intra city rail transport infrastructure

The rail line plan, superimposed on the road structure plan proposed in draft


master plan (CRDA, Figure 4.18 in page 37) is given in Figure 1. Approximate distance of the rail lines works out to:
·        Inner ring: 60 kms
·        Outer ring: 120 kms
·        North South corridor – 50 kms
·        East west corridors -2 corridors: Total length 80 kms
·        Spurs to adjacent cities/towns and railway routes: Approximately 190 kms
·        Total length: Approximate length – 500 kms

Amavarathi area map: With proposed rail connections

Investment for constructing 500 kms of the surface rail works out 50 km of elevated metro cost – as the costs are one tenth; are 35 % of the total metro system planned (0.35 * 147 = 51.5). 
The above are a rough estimate and the actual track length can be assessed based on detailed surveys but the deviation would not be more than 10%. Assuming the higher figure of 550 kms and also assuming that part of the system would be elevated - especially at the junction locations and at water bodies;  costs would still not be more than 50 % of the amount spent on the elevated system. The remaining 50% investment can be used for improving the connectivity to the capital region and in other parts of the state.
As seen above as the capacity created on a surface rail is 2 times of an elevated system; a 500 kilometre surface rail network will have capacity equal to that of a 1000 km metro rail; i.e. nearly 7 times of the proposed elevated track of 147 kms (147*7 = 1029 nearly equal to 1000) deploying half of the resources.
Hence the proposal is to plan a surface rail with good connectivity in the complete city. Alongside the surface rail system if a well laid out cycle, pedestrian and BRT network is developed the city should aim for very high levels of public transport use. Mumbai has around 80 % of public transport share and the same can be planned for Amaravati.
Additional spin off benefits are affordability and economic viability compared to the elevated metro owing to the lesser investment required and higher capacity created.
Surface rails can be developed strategically. Initially as the city would be smaller two lines would be developed to serve both the intercity and intra-city traffic. Initially, urban trains would be run to 5 minute frequency in the peak hours and 10 minute frequency in off peak hours. As the demand for urban traffic grows number of lines would be increased to four; where two lines would be used for urban and long distance traffic and two lines would be used exclusively for urban traffic. This transition can happen when the city size grows beyond 2 million – estimated to happen after the 20th year. However, a 40 metre land – required for four lines; would be reserved along the corridor.

3.4 Land requirements for rail

Development of Amaravati capital region is divided into three phases spread over an area of 391 sq kms. Out of this area the master plan does not assign any land area for rail development though elevated metro rail and high speed rail are planned. While the elevated metro could be planned to run along road medians; high speed rails running on the road medians is beyond author’s ken. Thus provision of land for high speed rail is essential but is still not provided in the plan.
While railways are not provided land in the development plan roads are provided
3892.4 hectares (9.94 % of the total land). Interestingly and paradoxically, elitist sport like golf is assigned 383 hectares (0.98 %) of land in the master plan.
As we have established earlier that provision of surface rail is important for the Capital region. Out of the 500 kms proposed around 310 kms would be within urban areas and 190 kms - spurs connecting adjacent towns and rail lines; would lie outside Amaravati region. Land required for the 310 kms of urban traffic is assessed based on the following assumptions:
·        Along the 310 km rail alignment: 40 metre wide corridor to build 4 rail lines– two lines for intra-city traffic and 2 lines for intercity and intra-city traffic.
·        Stations for urban traffic at 310 stations (@ 1 station per km): 400 metres in length and 40 metres in width
·        Major terminals (for inter-city traffic and yards) 8: 2 kms in length and 100 metres in width. (around 50 % part of the land – related to yards;  can also be planned outside the Capital region)

Land required is estimated to be 1896 hectares accounting for 4.8 % of the total land. On first impression it may appear as a large requirement as the original plan did not have provision for the land. However, the following two arguments – first based on transit oriented development and increased floor area ratio (FAR), and the second based on equivalent road space required to create same capacity; will be used to establish that the land proposed to be provided is much less compared to the benefits that accrue to the city.
Provision of rail corridor will create an important transit corridor enabling Transit Oriented Development (TOD). A key feature of TOD is permission of higher density of construction in the TOD corridor. For example, in Delhi in the Metro corridors the FAR was increased from 2.5 to 4 in the influence zone – defined as 500 meters wide on either side of the corridor (Press information Bureau, 2015). What it implies is that the builder is allowed to add 1.5 sq mts of built up area (increase from 2,5 sq mts to 4 sq mts) for every 1 sq meter of land. If we apply the same logic the total area in the influence zone of Amaravati rail transit corridor would be 310 sq kilometres (310 km multiplied by 1 km width) or 31,000 hectares. Even if we assume an increase of FAR by 1 unit (1 sq mt of additional built up area for every 1 sq mt) and assume that 25% of the land is available for development on the corridor the additional built up area would increase by 7750 hectares (25% of 31,000).   Thus a very conservative estimate shows that sparing 1 sq mt of land for rail development would increase built up area by 4 times.
Second way to look at the issue is the efficiency of space usage in terms of capacity created. A surface rail line will have capacity of 60,000 per direction if it is a double line and as the proposal is to provide 4 lines (quadruple lines) the total capacity would be 1,20,000 (1.2 lakhs) persons per direction per hour. As against this, the capacity of 40 meter wide road under different traffic conditions, given in Table below, varies from 36,300 to 9,600.  The Table shows that to create same capacity land required for roads varies from 330% to 1250% of the land required for rail.

Thus reserving land for rail corridors would be an efficient use of space and the plans should be modified to include the land required for rail.

4   Terminals, Parking and Transport Hubs

Terminals are an essential part of public transport infrastructure and they are required for commercial services such as passenger and cargo handling and non-commercial services such parking of vehicles to be available for service and the MRO (maintenance, repair and overhaul) activities for vehicles. Parking for private transport including cycling is another critical component of transport infrastructure.
The draft plan refers to transport hubs as terminals for interchange of passengers, areas to meet the shopping needs of commuters and also meet the parking requirements. The plan, however, does not cover the various principles to govern transport terminals and parking. Policies to promote the basic principles of people’s first and consistent with the national urban transport policy are enunciated below.

4.1 Extant practice and the implications

Traditionally terminals are planned in a disintegrated manner and as per the needs of each mode of transport. Within the mode, most of the large terminals, usually located in the heart of cities, are self-contained – they have facilities for commercial and non-commercial activities. Terminals of different modes are dispersed not only inconveniencing commuters but also discouraging use of public transport. Further, in many of the terminals located in the heart of the city MRO activities are also located and is a wasteful use of precious land resources as the activities can be located in the suburban locations but still meet the operational needs.
Hence the following would be followed while designing terminals:
·        Commercial activities (booking of passengers and goods) of all modes are located as closely as possible
·        Inter-city terminals are closely located and inter-linked and intra-city terminals are linked as much as possible
·        All the inter-city terminals should be designed as large commercial complexes with sufficient shopping and parking space
·        Intra-city terminals are two types: and inteminals
·        Provide parking for all types vehicles in the terminal or close to the terminal
·        Provide spaces for MRO activities on the suburbs keeping minimal emergency facilities in the heart of the city

Parking is a critical issue which can be leveraged to achieve the desired objectives of increased use of public transport and non motorised transport, and reduced motor vehicle usage. With reference to car and motorised two wheelers some of the policies to be followed are:
·        Linking mandatory availability of parking slot for vehicle registration: All motorised vehicles owners - both cars and motorised two wheelers; should show a parking slot for granting license for the vehicle. Though it looks revolutionary it is possible to implement in Amravati city by leveraging technology. It is essential that computer systems of road transport authorities and city planning authorities are interlinked. Such a system is in force in Aizwal – capital of Mizoram.
·        Ban on street parking
·        Provide maximum parking at the proposed transport hubs.
·        Increasing parking rates to reflect realistic land rates and vary the fee as per demand. People using public transport may be given concessions in the parking fee - graded as per the extent of public transport use.
·        Concessions to physically challenged, elderly and those with restricted mobility in parking access and provision of battery operated public vehicles to meet their needs.
·        Smooth access to parking areas for trolleys and other manual goods carriers to parking slots.

Similarly, cycling policies should help in increased use of non-motorised transport and public transport. Some of the proposed policies are:
·        Provide cycle parking slots as close to the place where parking is needed; at work spots, at transport terminals, and in residential areas.
·        All transport terminals including small bus stops should have cycle parking facilities
·        Parking should have nominal fee (nearly free) but regulated to ensure that the resources are not exploited by the unscrupulous.
·        Fully loaded cycle parking facilities should be provided in all transport hubs and also at other places so that the facilities are not more than two kilometres apart. Some of the facilities to be provided at these points are; shower and change rooms, lockers, cycle sharing and hire, and cycle repair. Even cycle sales points can be provided optionally.   
·        Rain shelters for cyclists should be planned as a part of the parking facilities. Rules should be so designed to prevent misuse.
·        All work locations should have cycle parking with shower and locker facilities. For larger employers they should be provided by the organisation and smaller can subscribe to common user facilities planned by third party or government.

5  Conclusions

From the foregoing it is seen that the plan has some positive features as it provides for hierarchy of roads, provides for pedestrian and cycle pathways sorely missing in many other cities, and BRT corridors.
An important weakness is the choice of costlier elevated rail corridor for mass rapid transit system without assessing a low cost surface rail system. Further weaknesses are not giving overall perspective for implementing the pedestrian and cycle ways proposed in the plan and this weakness gets accentuated if one reviews implementation of urban transport plans in various cities in the across the country. Plan for intercity transport is an Achilles heel with complete reliance on the proposed vision plan for high speed rail system and the conventional bus system ignoring connectivity to the Indian Railway network.
The article gives outline of the policy measures required for addressing these concerns and the implications for transport planning for the city. It suggests that cycling and pedestrian paths should have the highest priority in planning the road network. The pathways should each be 3.5 metre corridors on either of the road for all streets wider than 40 feet and 2.5 metres for all other corridors. The NMT corridors should have provide shortest connectivity and with at grade crossing to extent possible.
The article also gives how the proposed 147 km rail corridor can be replaced with 500 km rail network costing 50 % of construction cost proposed for elevated metro. Out of this 310 km would be serving the urban transport needs of the city and 190 km would be rail lines to adjacent cities and or rail systems. 500 km rail network would create a capacity of 7 times proposed metro rail at half the construction cost. The proposal requires around 1896 hectares of land which at first glance would appear to be very high. However, the land is only one fourth of additional built space added as consequence of transit oriented development. Alternately the land requirement is one third to one twelfth of the road space if the roads are to be built for the same capacity.
The plan gives outlines of integrated transport terminals which should include services for all modes, parking and shopping in one location.
