3 Introduction Lahore the second largest city of Pakistan and largest city of Punjab Expansion of Cities due to migration With the expansion of city, various problems are originating: Travel time loses Environmental degradation Fuel and economy losses Different researches suggest to plan cities in such a way which promotes smart growth which eventually control all losses

4 Literature Review Spatial pattern of human activities in definite point at a particular time is defined as urban form (Anderson et al., 1996). A dramatic change in urban form in world happened when automobile hit the market and heavy investments have been made on road network led accessibility of inaccessible areas (Maoh & Kanaroglou, 2007). This expansion creates a lot of problems like traffic congestion, high prices near work zones, fuel losses etc.

5 Literature Review Monocentric cities could be found in European, Chinese and Japanese metropolitan areas whereas North American urban areas American and Canadian, in contrast, are mostly decentralized and low density neighborhoods (Rodrigue, 2006). Urban form investigated by density, diversity and design of particular area (Axisia J.J, 2009). Different researches investigated about the urban form and its relationship with different transportation variables, Travel Patterns, health activities etc No research have been conducted in Punjab to investigate the Urban form of cities.

6 Objectives The research objectives are as follows: To compute the urban form variables for Lahore and Neighboring cities. To compare the urban form of Lahore city on two different levels (Town and Union council). To investigate the urban form of neighboring cities of Lahore.

7 Methodology Data collection Data Analysis Investigation of Urban form Software used for analysis is Arc GIS 9.3

8 Data Collection Lahore Urban Transport Master Plan 2012 Urban form Variables on Union Council and Town Level Shape file for each city was developed on Arc GIS 9.3.

9 Data Analysis Investigation of Urban Form: Population Density: Population Density (P.D) = Population/Area Employment Density: Employment Density (E.D) = Employment/Area Mix Density Index: Mix Density Index = (P.D*E.D)/(P.D + E.D)

10 Data Analysis Entropy Index: E.I = - P k.ln(p k )/ln(k) P k = Proportion of Land use k K = Number of Land uses Accessibility Index to Population: A.I(Pop) = Population of area i /(Travel time from area j to i) 2 Accessibility Index to Employment: A.I(Emp) = employment of area i /(Travel time from area j to i) 2

17 Accessibility Index to Employment

18 Result By investigating all urban form variables computed in this research on Town level, it was concluded that Lahore in monocentric in nature.

23 Accessibility Index to Population

24 Accessibility Index to Employment

25 Results By investigating all urban form variables the urban form of Lahore bridging towards sprawling.

26 FEROZEWALA

28 Employment Density

29 Mix Density Index

30 Entropy Index

31 Accessibility Index to Population

32 Accessibility Index to Employment

33 Results By investigating all urban form variables, it is concluded that Ferozewala has polycentric Urban form.

34 MURIDKE

35 Population Density

36 Employment Density

37 Mix Density Index

38 Entropy Index

39 Accessibility Index to Population

40 Accessibility Index to Employment

41 Results Muridkey has monocentric urban form.

42 PATTOKI

43 Population Density

44 Employment Density

45 Mix Density Index

46 Entropy Index

47 Accessibility Index to Population

48 Accessibility Index to Employment

49 Results Pattoki has monocentric urban form.

50 Conclusion and Recommendations Lahore has moncentric urban form when investigated on Town level and bridging towards sprawl when investigated on Union council level. Ferozewala has polycentric whereas Muridkey and pattoki, have monocentric urban form when investigated on Union council level. It is recommended to investigate Urban form on Union Council Level. It is recommended for policy makers in field of Transportation, Health, education and environment etc to develop relationship with urban form and policy accordingly. Masters plans of cities may be develop by considering the urban form.
