oad networking is an essential aspect of transportation and a difficult problem that has emerged in the urban communication technique. A excellent road network can play an powerful role in a smooth communication method. But it demands evaluation of many thematic parameters and components which are to be analyzed and to derive from them a strategy to put together a much better network such as provisions for greater road attributes, as road networking is connected to attributes of roads, landscapes, population and kind of urbanization. In the context of Guwahati city, fast haphazard urbanization took location throughout the past. Almost certainly, it occurred due to the lack of a suitable master strategy and non-implementation of the existing master strategy that needs more cooperation of the individuals with the municipal administration. As a outcome, urbanization has peaked with no consequent improvement of the social and physical infrastructures like new roads, bridges, settlements, organizations and institutions, and so forth. There is no doubt that Guwahati city is increasing tremendously with a modern appear. Simultaneously, other major problems are also increasing day by day which are mostly of urban floods, increasing neighborhood temperature, degradation of hills and forests, shortage of open spaces, and more importantly, escalating visitors snarls in all parts of Guwahati.
Road congestion is the major difficulty in Guwahati due to which regular targeted traffic snarls take location in all elements of the city. However, the government has taken many innovative measures, being implemented step by step. These incorporate widening of GNB Road and GS Road, clearing of MG Road, setting up dividers on significant roads, building of a handful of flyovers at busy places, which are virtually successful remedies of quick-term measures. Moreover, management of the social infrastructure system like upgrading parking provisions, changing of school timing, shifting of bus station, greater traffic manage operation, and so on, are successful actions that have been taken up by the authorities.
In common, avoiding targeted traffic congestion and saving time is immediately proportional to lower of pollution in the urban atmosphere. The guiding aspects of road alignment and smooth network are the two essential parameters that aid in the management of smooth targeted traffic operation. The way of communication is also an essential element to ease traffic flow. The physical infrastructure like roads, railways, monorails, underground metros, flyover, ropeways, and tunnel are the types of land and subsurface communication units in the metro cities depending upon feasibility and necessity. From the point of terrains and landscape of Guwahati city, there is a lot more scope for preparing a much better communication network for the city.
In the city, the site visitors congestion has been a main issue prevailing for the final few decades. Lack of proportionate attributes of roads, population explosion, peak amount of automobiles, fast urbanization, place of social infrastructures, complex acquisition of lands, habitations ahead of construction of roads, shopping location with out parking place and so forth are the elements responsible for the visitors congestion. It has been identified that in 150 sq km of core area of Guwahati, practically 60 sq km (44%) is covered by the denudational hills and remaining 56% i.e. 76 sq km lies in the alluvial plains. Hillocks occupy a significant portion of the city, which no doubt add to the organic landscape. A bird’s eye view of the city shows only 16 km in between the Saraighat Bridge and Narangi Tiniali along the east–west aerial distance. Likewise, it is only 9 km in between Lokhra and Umananda Ghat along the north-south course. The crucial city roads like Lokhra Road, Fatasil Road, RG Baruah Road, VIP Road and several link roads are connecting the suburbs to the main city. These city roads are directed towards the central Guwahati zone and meet the two major roads — GNB Road and GS Road. It is a single of the significant factors for high visitors volume in these two roads. It could be noted that the primary city roads are aligned in north-south course. There is only one significant road, which is the GNB Road (cum MG Road) that connects the city ends among Narangi and Jalukbari, except the NH-37 that has followed east-west trend.
The distribution of population size is also a concern for a smooth communication network. The city’s 4 components are basically northeast, southeast, northwest and southwest. Communication among the southwest and the northwest parts of the city does not have a easy road network. An innumerable number of city roads are accessible in the northeast portions and this portion has to take enough load of automobiles from each and every quarter of the city’s targeted traffic. As a outcome, traffic problems are continuously rising on these two key roads, namely GNB Road and GS Road. From the preliminary research it has been found that at least 1 main road is essential in the east-west trend through the middle corridor of the city.
There is a quite tiny scope for development of a road in the east-west alignment among the portion of NH 37 and GS Road due to heavy density of settlement. In the quick-term measures, Kahilipara Road might be employed as a busy road if it extends in the western path. If the higher Dispur area can be linked with Maligaon area through the Kahilipara Road then there is a maximum probability of decreasing traffic congestion on GS Road and GNB Road. About 95% of the city buses run by means of these two roads. This is only because of shortfall of road alignment in the east-west trend.
It may be talked about that from the preliminary observations, a 2.2 km length of roads getting the tunnel length of about 1.five km would be the most successful measure in minimizing the current distance of critical areas of Guwahati city in in between southeast and north-northwest. A 1.5-km tunnel through the Fatasil hills would be most efficient in lowering the current distance of about three.7 km among the Fatasil Ambari and LCB College, four.six km between Dispur and Maligaon, 7 km amongst Lalganesh and LCB College and around three.five km amongst Six Mile and LCB School respectively. Moreover, there will be a maximum probability of reducing about 20% traffic volume on the busy GNB Road and GS Road. This route alignment would reduce the visitors jam in the central part of the city like Fancybazar, Kumarpara, Gopinath Nagar, Paltanbazar, and so on. It is high time to search for an choice route in the proper geographical place giving specific emphasis on linking of East-West corridor by taking complete advantage of the Kahilipara Road, link road of Fatasil and Lokhra Road for establishing far better communication among the central, southeastern and southwestern elements of the city. This is also critical from the point of strategic geographical area and the demographic pattern. The proposed tunnel web site can be simply created by minimum damage of public property rather than constructing a road on the plains.
It may possibly be talked about that there is a narrow road named Dilip Huzuri Path that connects Fatasil and Maligaon places by means of the Fatasil Hill. Maximum utilization from this road would be a fruitful measure concerning the visitors snarl near the Paltanbazar locality. Aside from, at least a two-lane road tunnel by means of the Fatasil hills is urgently essential maintaining in view the various benefits due to diminished distances amongst the northwest and southeast components of the city, saving time and income. The road tunnel beneath the challenging rock terrain in the surface level is a achievable selection and the related departments may come forward positively with the investigation and feasibilities. This mega infrastructure inside the tough rock terrain could be really safe and resistant to seismic activities than the valley fill deposits. It is also a very viable choice for easy availability of raw materials for mega infrastructure.
From the preliminary spot survey, it has come to light that around 20 to 25 per cent of men and women travel by mass transport technique towards the western side of the city beyond the Maligaon area. The southern portion of Guwahati is also emerging as a main urban place due to setting up of distinct mega social infrastructure like stadium, bus terminus, educational institutions, trade and commerce outlets, and so forth. There is a maximum probability for growing site visitors volume on the National Highway-37 keeping pace with fast advancement in its contiguous locations. The proposed road tunnel would undoubtedly aid in reducing traffic congestion in the NH-37 in the near long term. The tunnel option to ease targeted traffic can also be fruitful in other hills like Kalapahar, Japorigog, and so on.
Space technologies can offer existing road database of Guwahati which can help in transportation preparing, style implementation, upkeep of transport project apart from targeted traffic management. A correct visitors management program may be carried out to uncover an effective navigation/transportation system in the city of Guwahati to make it a soothing spot for road users.
