crowdsourcing the city
elevator usage in crosby
This project is about the usage of elevators. It is to find out ‘what drives people to take the elevator?’. Elevator is not just another feature in a building, it is about vertical circulation. I am amused about the different parameters that drive the users of a three (or four) story building to use an elevator, either on a regular basis or otherwise.
Survey process:
Survey was done in the elevator for 3 times a week from 9 am to 9 pm. The days of the week were:
Thursday Friday Sunday
The reason for the selection of these particular days were:
a) The two year students have thier studio on the third or the highest floor level of Crosby hall.
b) I wanted to have atleast two week days in my survey
a) The three-and-a-half year stu-dents have thier studio on the second level of Crosby hall.
b) Friday is the last day of the week, hence the enthusiasm is at a different level.
c) I wanted to have atleast two week days in my survey
a) Its a weekend and I wanted to have either of the weekend days in my survey.
b) People get back to studio work on Sundays after enjoying the Friday evening and Saturday.
The survey was done by sitting in the elevator voluntarily.
Everytime some one entered the elevator, I filled out a survey for by questioning the elevator user while they reached thier destination. The form was:
I based my survey on teh following parametrs:
Age Fitness Time Gender
Results:
I analysed the collected data on the basis of:
a) Age of a user - students or facultyb) Fitness level of a userc) Time- of the day and weekd) Gender of the user
The comparison and data analysis:
a) Gender
Fitness level amongst male users Habit of taking the elevator by male users Direction of the elevator usage
Elevator usage on thursdays Elevator usage on fridays Elevator usage on sundays
Fitness level amongst female users Habit of taking the elevator by male users Direction of the elevator usage
Elevator usage on thursdays Elevator usage on fridays Elevator usage on sundays
b) Time of the day
Fitness level of the morning users Males-Female users Habit
Time of the week Direction
Fitness level of the afternoon users Males-Female users Habit

Fitness level of the evening users Males-Female users Habit

c) Fitness level of the users

Male-Femal who don’t excercise Age Time of the Day Habit Direction
d) Time of the week

Friday-users fitness level Male-Female users Time of the Day Age
Sunday-users fitness level Male-Female users Time of the Day Age

modelling the system
The model of the system was to represent the inter-relationsip of three basic parameter I choose which played a crucial role in the system. The three parameters were:
a) Gender dependencyb) Time of the day dependencyc) Fitness level of a person dependent
To model out the system I made 3 attempts:
a) First attempt:
I tried having the three parameters depend on one anaother which coul be represented by the length of the wire pulled to move a measured weight by a certain distance, which could be measured by the measuring scales on the either side. But due to the materiality I failed in this model.
b) Second attempt:
Once I got the right materials in place to represent my system, I discovered that it was a very affective system. It had a lot of flaws and was unble to show the inter-relationships and dependancy I wanted to represent.
Hence I again tried to get the components of my model system right to be able to represent the system correctly. The basic components of a moving pulley are:
Length of the rope travelledto pull the weight up
The diameter of thepulley wheel
The wight attached to be pulled up by the moving pulley
c) Third attempt:

transposition- Bike Hike
Similarity between Bike usage and elevatoe usage
Limited to certain people of the building
Limited to certain people of the society
Usage influenced by time of the week and time of the day
Habit dependent
Weather/ season influences the
usage
Age dependant
Usage dominated by male users
Fitness dependant
Hence I finalised the Bike usage to be the most appropriate transposition. Both are dynamic systems and overlap in a lot of areas as shown above.
To proceed with this I did information study online, listning to court hearings on Bike Usage in NYC. I went through a lot of statistics with different modes of transportation and comparison over the year.

Site Study
To carry out this more effectively, as site study was necessary. I choose and limited my self to the West side be-cause the West side was one potential area where I could find all the four different kinds of bike pas which are present in NYC.
Hence I choose a weekend day and a working day, hired a bike and went up and down West side. The pictures below show the four different kinds of bike lanes in NYC.
Along the Hudson- dedicated and saperate bike
lanes
Along 106th street- designated
bike lanes
Along Cnetral park and 10th ave- only signage indicating bike lanes
On Broadway- dedicated and protected bke lanes

b) Cars in the Bike Lanes
Chornological of the process Bikes with camera attached
The camera can be issued by a Bike management auhtority. This camera is easyly fixable at the front handle bar of the bikes. Once the bike is in the bike lane (only), it will detect the car in front of it and start recording. The car’s license plate can be captured, sent via internet to the DMV Traffic Voilation Authority. Unless the car was not being parked, it will get a ticket. This has another advantage apart from the cars and cabs to be out of bike lanes, it will help keep the biker in bike lanes only as it seems to be a big problem in NYC.

Scope of Improvment:
a) I can look at the project from a very different point o view still keeping the bike lanes in mind.b) I can look at the improvement of bike lanes from a very urban scale. I can bring about changes at the city level, and re-designing the steet system on NYC.
