Introduction
The different phases of urban development are related to the
economic development of transportation. The 20th and 21st
century, mass industrialization led to a car-centric development and walking or
cycling became impractical
Each of these transport air pollutants affects human health
differently. Carbon Monoxide (CO) results in anaemia and cardiovascular
diseases, Sulphur Dioxide (SO2) when combined with particulate matter and
moisture causes lung diseases, Nitrogen Oxide (NO) causes irritation of upper
respiratory tract, development of anaemia as well as heart diseases, Lead
causing long-term adverse impacts such as haematopoiesis derangement and
damages to liver, kidney and the immune system are some examples. A passenger
car absorbs more than 4 tonnes of atmospheric oxygen annually, releasing
approximately 800 kg of carbon, 200 kg of various hydrocarbons and 40 kg of
nitrogen oxides
Another negative impact of motorized transport on humans is
traffic-induced noise. In urban areas, road traffic is the major source of
noise and as the intensity and speed of traffic rises, the noise level
increases. Apart from the irritating effect, noise also causes stress and a
rise in blood pressure in individuals. The noise level is influenced by several
factors such as traffic flow intensity, composition and speed, engine type,
type and quality of road surface, percentage of green space and spatial planning
decisions. Speed reduction, redistribution of intense traffic flows around
residential areas by introducing sanitary protection zones, etc are some
measures to control noise pollution.
Beginning with Jacobs as early as 1960s, many urban
reformers and global institutions have highlighted the value of urban
environments. They have led to numerous movements that advocated environmental
sustainability and healthy lifestyles. Promoting the use of private vehicles
for travel along with several other reasons such as use of internet and its
services and automation of labour processes have led to population becoming
hypodynamic, characterised by reduced activity. It is one of the causes of
depression, diabetes and obesity
Policy makers and planners around the world are putting all
efforts to create livable cities. Sustainable urban mobility offers efficient,
cost-effective transport options giving access to key destinations and services
with reduced levels of energy consumption and pollution. An integrated and
balanced development of all transport modes is one of the main characteristics
of Sustainable Urban Mobility Plans (SUMP) and also a key goal in the strategic
EU policy
The International Physical Activity and the Environment
Network (IPEN) project establishes a relationship between physical activity of
people with the environment they live in. The main determinants are distances
from residences to shops or schools, street density and land use distribution. Active
mobility, including walking and cycling in combination with public transport or
as single trips, is being promoted by health professionals and World Health
Organisation (WHO) to tackle problems of physical inactivity. Active mobility, also
referred to as ‘active transport’, ‘active transportation’ or ‘active travel’
have different infrastructure requirements. They are high-capacity modes of transport
which has proved to increase the flow of people without substantial space
consumption. Active mobility creates employment, makes our cities more
attractive, reduces congestion on roads and helps tackle costs of health
services related to physical inactivity. Policies at national and local
government levels should be introduced to incorporate walking and cycling infrastructure
in transport plans
Kochi, the capital city of Kerala is the most densely
populated city region in the state has a population of 2.1 million
Transport network in Kochi consists of water, rail and
land-based modes. Buses account for more than 40% of trips though it comprises
only 2% of vehicles in the city. The modal split as per 2011 census is 4%
walking, 15% cycling, 67% public transport and 14% personal car. Estimates show
that there is one car for every five individuals in the city compared to eight
at the state level. However, introduction of Kochi Mobility Hub and Kochi metro
system has increased the awareness of public transport framework and its
position in sustainable mobility. Kochi is also part of the Ecomobility
Alliance, which is a group of ambitious cities who aim to create and implement
urban mobility strategies that prioritize environment and the people.
Analysis
Similar to other Indian cities, Kochi faces a chronic
traffic congestion with auto-rickshaws serving as the intermediate public
transport (IPT). Kochi’s transport sector accounts for 20.2 percent of Particulate
Matter (PM) 2.5 concentration in the city. The most noteworthy contributor to
the city’s transport related emissions at 93 tons per day are auto-rickshaws.
It is responsible for significant amounts of harmful pollutants per day,
including carbon monoxide (3.1 million grams), PM 2.5 (1.48 million grams) and
nitrous oxide (3.84 million grams)
The ‘Smart Mobility through Zero Carbon Footprints’
introduced in 2015, also aimed to provide access to public transport for
citizens within 250 metres of their residence or workplace, encouraged walking
and cycling across the city, ensured better accessibility to senior citizens,
women and children to public transport and make Kochi’s public transport
pollution free by 2020. The Master Plan of Kochi has included a comprehensive
transport development plan to improve the transport infrastructure.
Walking and cycling are common and basic modes of transport
around the world. Providing good quality infrastructure for walking and preventing
pedestrian collisions should be thus, an important and achievable policy goal.
The 2009 report by World Health Organization (WHO) analysed the causes of
accidents and policies in cities and concluded that pedestrians, cyclists and
motorcyclists are highly unsafe, specially without the protection from
motorised vehicles. To reduce the number of road traffic deaths and to promote
NMT by the Decade of Action for Road Safety, it is critical
to make walking and cycling safe. There are policies at the state and central
government such as parking policies, hawker policies, the National Urban
Transport Policy (NUTP) 2006 under the National Urban Renewal Mission (NURM),
Kerala Road Development Policy (Draft), 2009 and Transport Policies for Kerala,2011
that give priority to construction of cycle tracks and pedestrian paths to
enhance safety of users and promote the use of NMT.
Estimates show that the cost to provide pedestrian
infrastructure for 1 kilometre is only one thirtieth of that involved in making
a flyover of the same length, whereas the number of pedestrians will be 10
times more than private vehicle users. The pedestrian count study done by
Health Bridge, during week days and weekends show that irrespective of peak or
non-peak hours, the number of pedestrians at any segment in the city is 2000 or
above. The walkability index is 0.53 according to a study by National
Transportation Planning and Research Centre (NATPAC), in 2013. These numbers call
for attention for adequate active transport provisions.
Poor planning and lack of poor apathy for pedestrians has
led to insubstantial or non-existent pedestrian infrastructure in Kochi,
especially for persons with disabilities. Footpaths are characterized by broken
slabs covering drains, uneven surfaces, encroachments by vendors and hawkers
and garbage disposal. The Panampilly- Nagar walkway, known as streetscape,
launched by the Kochi Metro Rail Limited (KMRL) in 2016, has been in a
dilapidated state for the past few months. Similarly, the recently renovated
Marine Drive walkway belonging to the Greater Cochin Development Authority
(GCDA), has turned into a waste dumping yard because of lack of provision of
waste bins.
Active mobility is a common form of physical activity and
empirical evidence shows that the quality of walking and cycling in a community
affects their physical fitness and health substantially. Apart from the health
benefits like weight management, developing core and leg strength or reducing
stress levels, cycling also influences cityscapes and mobility cultures. In
January 2021, the Cochin Smart City Mission (CSML) built cycle lanes on six
arterial roads in the city as part of the ‘India Cycles 4 Change Challenge’
with the support of the German Agency for International Cooperation (GIZ). They plan to scale up
cycle tracks all over the city with time.
Kerala government had earlier this year launched key road
infrastructure projects under the CSML under which 35
roads in Kochi city and the West Kochi are being renovated. Vasco da Gama
Square, Dutch Palace entry area, Marine Drive walkway and Open-air auditorium
at Fort Kochi are some of the chosen roads to be renovated. Six among these
roads are upgraded as smart roads with dedicated utility ducts, road furniture
such as walkways, cycle tracks, signages, bus bays, zebra crossings and smart
road features.
Proposal
To increase the awareness among public, active mobility should be ideally
established as an integrative approach to promote safety, healthy and liveable cities.
To address low walkability in Kochi, law enforcements for maintenance and
cleaning of footpaths should be adopted. This would include quality checks of
footpath surfaces and pedestrian infrastructure. A permanent hierarchy of
streets should be developed and NMT only streets shall be designated as per the
Indian Road Congress (IRC) 103 guidelines. Permanent installation and
maintenance of basic facilities like drinking water, toilets, emergency booths
and strict enforcements against tampering of these items should be ensured.
Wayfinding signages to indicate resilient and safe zones, local hospitals and
emergency services can also be helpful to pedestrians. Periodic public
consultation is also necessary to build awareness among citizens.
Walking and cycling must be encouraged and facilitated as a
primary mode for short trips within the neighbourhood and city. Dedicated and
demarcated cycle lanes must be assigned and potential spaces in front of
buildings, streets and vacant public land for permanent parking infrastructure
has to be identified and developed. Introducing incentives for adopting NMT
could also attract more people and develop this practice.
Conclusion
Traditional planning often assumes that the primary goal is
to maximise travel speed while minimizing physical effort in urban areas, where
majority of the world’s population currently reside. Mobility has become the
key dynamic of urbanization with its infrastructure being the foundation of
urban form. Despite the increase in investments and initiatives in urban
mobility, accessibility to places, activities and services is becoming
increasingly difficult. Cities today are characterized by accessibility crisis
and negative externalities.
Active mobility, i.e. walking and cycling are not only
healthy on an individual level but they are also cheap, carbon-neutral and
space-saving when compared to other modes. However, their share in the modal
split is still comparatively low in many global cities. The willingness to
change individual behavioural patterns is also requisite in triggering
behaviour changes in urban mobility. Either, people are unaware of walking and
cycling alternatives to common mobility habits or the provided services and
developments do not meet expectations of people who eventually refuse to accept
them.
Kochi, the densest urban agglomeration in Kerala faces
infrastructure deficits in ensuring pedestrian rights. Strategies to encourage
active mobility and development of associated infrastructure should be a
priority in future investments and city mobility plans. To increase the
participation of city dwellers in active mobility, authorities should ensure dedicated
lanes for walking and cycling, traffic calming measures, well maintained and
lighted footpaths, easy access, checking illegal on-street parking,
streetscaping, implementing street vendor policies, integrating different
public transport modes and conduct awareness programmes.
