You should collect information related to the different transportation modes in the area: pedestrian, light rail routes, ferry, bus routes, communter rail and inter-city rail. Remember that the changes around Sirkeci represent a major change to the character of the area and also an opportunity to restructure the area for transportion. The area is a significant intermodal transfer center between buses (transfer center located on the other side of the western side of the Galata Bridge), ferries, light rail, communter rail and inter-city rail. What about the presnet coordination between the modes at this location? Also, there is a major bus transfer center on the periphery of the area near the Covered Bazaar that might be considered and studied. Buses run along Kennedy Caddesi--is this street under-untilized and could this be an area for an exclusive bus lane.
Mehmet brought up the idea of this area being a car free zone----which is being considered by the Metropolitan Governement. What are the problems relating to its implementation and how could they be mitigated?
In inspecting the street network, you should inspect the functional classification of the streets in this area. Where are there streets that are entirely pedestrian, transit-only, narrow with mostly pedestrian activity but allowing vehicular traffic, arterials, collectors etc. Also, what accomodation has been made for persons with physical handicaps.
We have a GIS database for this area that includes the bus routes, streets and land use. This should be utilzed and reclassified for the needs of your section.

Büyükçekmece lake represents an important drinking water resource and supplies apart from other reservoirs the inhabitants of Istanbul with fresh water (Başak & Alagha, 2004: 1). But the quality of the provided water is suffering from the unplanned and rapid increase of Istanbul. The growth of Istanbul into its periphery causes major land-use changes. The area sourrounding the Lake faced, according to Geyman & Baz, a growth rate of built-up areas (housing density less than 60m) from 1,149 ha (1995) to 1,639 ha (2005) (Geyman & Baz, 2007: 7). The city is facing an enormous demand for housing caused by high migration rates. To supply these demands, the urban sprawl reaches up to the watersheds. This leads to reduction in water quality and other environmental impacts. Around the Büyükcekmece lake developments being noticed, comparable to the past evolution of the area of Kücükcekmece lake which are already researched by DEMiRCi et al..
In the past, district municipalities and other in planning processes involved institutions tried to regularise the growth and the risks evolving out of the growth. The efforts which should reach the intended goals were adopting planning methods and strategies, land-use regulations and zoning in form of new laws. But in fact this does not lead to the desired goals. Unfortunately, the outcomes were quite contrary to the original intention. Geyman & Baz came to the point that these efforts, „encouraged such activities, further stretching and degrading local natural resources because these developments suffer from improper and insufficient infrastructure facilities“ (Geyman & Baz, 2007: 2).
To follow this train of thought, I would suggest in face of the urgency in solving this problems and protect the watershed, it is necessary to invent adequate planning structures institutionally fixed.
The next step is to facilitate the land demanding groups of interests with sufficient infrastructure in the already used areas. The intention is to use the areas in the city that have been made available more sufficient and thereby protecting agricultural and untouched territories.
Besides, the government should work on breaking the primacy of Istanbul. The city already bursts at the seams and economic underdeveloped regions should also benefit from the prosperity of the economic growth. Breaking the huge flow of migrants to Istanbul, the solution may be governmental business development with the aid of subsidies.
At the moment, the water quality of Büyükçekmece-Lake is up to the standards of European Community and World Health Organization. But it will be necessary to discuss adequate solutions with all involved groups of interests. To diminish the pressures Büyükçekmece-Lake is facing it will be essential using above mentioned thought-provoking impulses.
