A node is formed by agglomeration ofcommercial activity around one or more adjacent roadjunctions. In the Kerala context where urban ruralcontinuum persists, each LSG is having at least onenode. In most of the cases area served by one nodegoes beyond the boundary of the LSG within which it islocated. In certain cases the nodes may be located atthe meeting point of the boundary of one or two LSGs.A separate study for nodes is necessitated since thenodes have entity independent of the LSG area. In thischapter on the hierarchy of nodes, urban and ruralgrowth centers of the District are identified.

9.1 EXISTING HIERARCHY OF NODES:

The hierarchy of a node is identified by theextent of activity taking place in the node. The extentof the activity is measured by a proxy indicator denotedby the hierarchy of roads (based on the administrativestatus) meeting at that place (the methodology isexplained in IDDP Kollam)

The hierarchy of the nodes in the descending order ofweightage is shown in Figure 9.1.

Vth order nodes _ all the remaining nodes selected forthe study are included in the category of V order junc-tions. A list of the nodes within the Palakkad District isgiven in the Table 9.1

Chapter -9HIERARCHY OF NODES

Accordingly the nodes (selected) of the Palakkaddistrict can be categorized into five.

Fig 9.2 Spatial Distribution of nodes

9.3. SUGGESTED FIRST ORDER NODE

Due to the meeting of roads of higher statusat Kannadi junction, Kannadi panchayat has highervalue and is derived as first order junction. Butconsidering the population distribution, centrality andadministrative status the highest node has to beprovided within Palakkad Municipal area. So the firstorder node is adjusted as to Palakkad which serve the

entire district.

9.4. SUGGESTED SECOND ORDER NODES

The second order nodes have to fulfill thefunctions of a city centre mentioned in the Town&Country Planning Organization (TCPO), Govt of Indiaguidelines for commercial facilities.

As per TCPO guidelines, city centre has to catera population of 3 Lakhs.

The service area is assumed to have a hexagonalshape, the area of which is determined by taking intoaccount the population density of the service area andthe population to be served. Since the populationdensity in midland and high land region of the Districtdiffers, area of hexagon in each of these regions varies.(fig.9.3)

The spatial distribution of nodes is shown on in fig 9.2

Fig 9.3 Size of service area polygon in different area Fig 9.4 Service area of existing second order nodes

The service area of the existing second ordernodes are shown in figure 9.4. From the figure it is clearthat the western and southern parts of the district arenot served by a second order settlement. The Pattambi,Ottappalm, Mudappallur, and Vallangi, four prominentnodes in the region are selected as the second order(proposed) nodes for these regions (Figure 9.5).Figure9.5 shows Kannadi, Nell ipuzha, Melepat tambi,Ottapalam, Mangalam and Vallangi as the suggestedsecond order nodes.

Fig 9.5 Suggested second order nodes Fig 9.6 Service area of existing third order nodes

9.5 SUGGESTED THIRD ORDER NODESAs per TCPO guidelines the third order nodes

have to fulfill the function of a Community centre forcommercial facilities. The community centre has tocater a population of 40,000. But due to dispersedsettlement in the district, the service population of theIII order nodes is taken as approximately 80,000. Asexplained earlier, service area of third order nodes inhexagonal shape is derived for each region.

The existing third order nodes with their servicearea is shown in figure 9.6.

9.6 INFERENCE

Palakkad is the first order node of the district

acting as a commercial centre serving the entire district.

The suggested second order nodes are Melepattambi,

Nellipuzha, Kannadi, Ottappalam, Mangalam and

Table 9.2: Hierarchy of nodes (proposed)The unserved area shows the necessity of a

third order node there and the modified situation with

new third order nodes are shown in figure 9.7.

The third order nodes are Goolikkadavu,

Kongad, Shornur, Koppam, Thiruvazhiyode,

Nagaripuram, Koottanad, Chittur and Kambrath challa.

The suggested hierarchy of nodes is shown in Table 9.2
