Technology, Operations and Decisions Sciences

1. Sustainable cities and transport

[a] Modelling cities and sustainability

• Developing mathematical models of land use and transport interaction (LUTI) (Adhvaryu & Echenique, 2012): Such models can be used to analyse the performance of combinations of urban form and transport policies under economic, environmental, and social sustainability criteria. Examples of planning policies are combinations of alternative land-use policies (eg, compact, dispersed, edge expansion, new settlements, etc) and alternative transport policies (eg, public transport improvements, highways investment, etc). To assess the sustainability of such policies, I have developed a mathematical model called SIMPLAN (Simplified PLANning) modelling suite (explained below). Such models have been extensively used all over the world to enhance the urban plan-making process. An application to Ahmedabad is shown in Adhvaryu (2010). Incorporating economics into models of cities aspects that strongly explain behaviour makes urban models more representative of the reality (as against the pure planning/engineering tradition of dealing with only physical aspects of cities). I am also interested in commercially developing simplified urban models (like SIMPLAN), for which the potential market could be governments in small towns and cities (both in developed and developing countries), who, to begin with could invest in developing such models with minimal resources.  Later on, if they wish, these could be easily updated as new data become available and easily upgraded if more resources become available, creating a long-term relationship with the clients. 
• Analysing the evolution of urban spatial structure (Adhvaryu, 2011b): Analysing the spatial structure of cities is important. It gives an indication of the trends the city is growing and proves useful in developing future scenarios for cities (in terms of alternative urban and transport policies).
• Critical review of development plans (Adhvaryu, 2011a): A critical review of the development plan is a precursor to developing a model for that city. It enables us to examine the approach critically in terms of what has worked and what has not. This analysis feeds into the formulation of more robust models.

• Visualisation of public transport accessibility levels that can be used in various policy decisions such as TOD and land use regulations, parking, affordable housing, and multi-modal integration. 

More about the applications of public transport accessibility levels (PTAL) in planning policy is available in the talk on "Public transport accessibility and planning policy: an Indian perspective" presented at the  hosted by Martin Centre for Architectural and Urban Studies, University of Cambridge, 28-Jan-2021 is available here.

[c] Investigating the relationship between energy use and urban environment and activity at both urban block and city levels

• Examples of urban environment and activities are density, built form, travel patterns, and type of land uses.

[d] Urban design aspects of city form and street patterns

• Investigating how, and if so to what extent, does physical design affect the way we make location and travel choices relating to housing, work, education, shopping, recreation, etc. 

2. Urban transport infrastructure - planning and design 

[a] Exploring alternative designs of road sections for a variety of urban uses

• Eg, residential, commercial, and mixed uses; accommodating transport infrastructure like bus-priority and busways, design of pedestrian-friendly and accessible streets, and accommodating non-transport uses such as hawking and vending; parking management

[b] Exploring the feasibility of bus-priority public transport systems in developing countries

• My MTech (URP) thesis explored the feasibility of busways in Ahmedabad (1995). In  2019, I co-authored a book chapter on critically analysing the Ahmedabad Bus Rapid Transport System that started operations in 2006 (see, Swamy, HMS., Adhvaryu, B., Sinha, S. (2019)).

[c] Planning and design of multi-modal transport hubs (for more see this article on MIEM students' studio work)

[d] Accident analysis (for more see this article)

[e] Design of accessible public transport infrastructure and developing criteria and methodology for evaluating transport infrastructure designs (Adhvaryu, 2006).

• My MSc Transport dissertation (2003) addressed the design of accessible public transport infrastructure.  Brighton Bus Station was used as a case study, with emphasis on bus station design in constricted areas (eg, historic city centres).  My interest here is to take up some unresolved issues for further research.

3. Advocacy for safe traffic

• During my tenure at CEPT (2001–04), I founded a voluntary agency called Safe Traffic Advocacy Group (STAG), which was involved in conducting several workshops, seminars, and public presentations for school children on traffic safety.  I believe that traffic situation in our cities could be only improved using a three-pronged approach—the 3Es explained as follows:
• Engineering: Developing confusion-free physical design of roads and junctions (including signals and signage) and adding new capacity and augmentations (if necessary)
• Education: Developing awareness and sensitivity towards other road users and safe driving habits, and
• Enforcement: Developing and updating traffic management plans, exercising greater vigilance by traffic police, stricter vehicle licensing, and ensuring road-worthiness of vehicles.

Urban modelling for enhancing master plan making: SIMplified PLANning modelling suite for Ahmedabad

An urban planning policy usually has two key components: the urban form and the transport system.  There can be a variety of theoretical possibilities of these two components and also how they can be combined.  Some typical urban forms and transport policies and their combinations are shown schematically in the figure below.

Policy-makers are usually faced with the decision of what planning policy to pursue in order to achieve the best possible future!  Using models that simulate urban dynamics, it is possible to test and assess alternative planning policies, thereby making the decision process more objective and transparent.  Examples are the full-fledged and complex land use—transport interaction models, which have been successfully applied in many cities of the developed world, demonstrating its effective use in assessing alternative planning and transport policies before finalising their master plan.  However, in the developing world, building such complex models is challenging due to lack of data availability and resource constraints.  Addressing such constraints, a SIMplified PLANning modelling suite called SIMPLAN has been developed for the case study city of Ahmedabad, India.  SIMPLAN is built using available census and some basic employment related sample survey data, and contains four sub-modules for spatial trend analysis, residential location, modal split, and alternative policy assessment framework.  SIMPLAN development is an attempt to build simplified yet robust analytical tools in the context of developing countries.

The four SIMPLAN modules are:

• Trend Analysis Module (TAM): a set of tools for analysing the evolution of the spatial structure of a city (for more details see Adhvaryu, 2011b)
• Residential Location Module (RLM): an econometric residential location model that uses average housing rents as part of the generalised cost in a gravity-type allocation function and currently deals with work trips. RLM estimates population distribution, by socioeconomic groups, as a function of employment location and residential floorspace (for more details see Adhvaryu & Echenique, 2012)
• Modal Split Module (MSM): a multinomial logit model to estimate the proportion of person work trips by different modes generated by the RLM (for more details see Adhvaryu & Echenique, 2012)
• Assessment Module (ASM):  After calibration, SIMPLAN can be used to assess alternative planning policies for a future/horizon year, with appropriate employment, dwelling floorspace, and transport inputs.  The key assessment criteria in are economic (consumer surplus in housing and transport), environmental (new land required and CO2 emissions), and social (distribution of economic benefits and mix of socioeconomic groups) (for more details see Adhvaryu, 2010). 

The main land use inputs to SIMPLAN are employment and dwelling floorspace by zones and transports inputs are average network distances and speed by mode. For Ahmedabad, three alternative policies for 2021 were tested: trend policy (business as usual), compaction policy and dispersal policy, with appropriate combinations of land use and transport inputs.

The main advantages of using this type of approach are:

• It allows planners to prepare policy alternatives with drastic variations and test these to see its effects in the future, enabling them to make more informed decisions for before arriving at the ‘most suitable’ policy to be pursued in the development/master plan (popularly known as DP).
• Outputs from the model are disaggregated by zones and therefore dovetail well with the next spatial level of planning, ie the town planning scheme (TPS).
• Quite importantly, since the model is spreadsheet-based, it is simple to understand and run.  All model runs can be out in-house by city planning officials on their PCs or laptops!  This avoids the ‘black box’ approach usually prevalent in planning projects involving mathematical modelling, wherein specific tasks are outsourced to private consulting firms.

The policies tested for the case study city of Ahmedabad for year 2021 include: [1] compact city with high-quality public transport [2] dispersed development with significant road capacity enhancement, and [3] trend policy, denoting a business as usual scenario in terms of supply of residential floorspace, development control regulations (DCRs), and public transport development (which acts as a reference policy to compare the policies developed by 'design').  Sensitivity analysis is also done to see the effects of change in the distribution of jobs. 

The critical review of the Ahmedabad Development Plan making approach (as in the Ahmedabad Development Plan for 2011) is discussed in Adhvaryu (2011a), establishing a need for a model-based plan-making approach.

Key SIMPLAN outputs (for Ahmedabad) indicate that dispersing cities proves to be economically beneficial to the society as a whole because households would tend to gain from the lower rents further afield.  Compaction policy performs better in terms of environmental aspects such as consumption of new land for development and vehicular emissions, but bearing in mind traffic congestion is currently not modelled, which could potentially reduce this advantage.  With regard to social aspects, it appears that any deviation from the trend creates a lopsided social mix, although compaction policy is a bit better than dispersal.

 As mentioned above, SIMPLAN is developed in a spreadsheet environment, with all key operations controlled by a visual interface using sub-routines written in Visual Basic Application code.  This creates a user-friendly graphical interface that makes the model simple to understand and operate by local planning agencies, and, in addition, provides them with the flexibility of updating the model as and when new data is available or a new round of census is conducted.

India is rapidly urbanising and is at a crucial juncture in its development.  The urbanisation phenomenon has both positive and negative effects.  It could be argued that appropriate urban development policies and planning methodology can use the potential positives to foster better equity of benefits from the booming overall growth.  On the other hand, if India does not capitalise on the potential advantages appropriately, then in the next few decades the negatives of urbanisation could amplify, worsening city living and becoming a stumbling block in its economic growth story.  It is believed that using a methodological planning framework such as SIMPLAN, cities in the developing world can prepare their own tailor-made policy that best satisfies their objectives, making the planning efforts count for improving the quality of life in cities.

A succinct overview of the SIMPLAN simulation modelling framework is discussed in Adhvaryu (2012).

2. NON-ACADEMIC APPS

Below are the non-academic apps I have developed to hopefully make the admin aspects easier (available on my website).

BaTeX: I like the simplicity of Markdown for small- to medium-length documents. However, I have struggled to find an application that meets my needs without requiring CSS tweaks, technical adjustments, or workarounds.

BaTeX is my attempt to build such an application: simple and fast. The simplicity comes from using Markdown, and the speed from being browser-based — meaning it runs entirely in your browser without consuming local resources. In addition, it provides a WYSIWYG, Word-like editing experience, with LaTeX support for mathematics, and PDF export — all completely free, with no features locked behind a paywall.

BaTeX (pronounced ba(h)-tek) brings together Ba and TeX. Ba stands for beautiful articles — written in Markdown with mathematics typeset in LaTeX — and carries a small personal signature through my initials.

eMergent: eMergent is an app that can send emails to several recipients with personalised messages and attachments - all at once. It is a standalone app, unlike some email addons that involve spreadsheet gymnastics!
