Land Use Plan for My CityOrf 467 Transportation Systems AnalysisFall 2007/8 Assignment #3Land Use Plan for My CityPreliminary layout Due: Wednesday, Oct 10, 2007; Trip matrices are due Wednesday Oct 17, 2007The objective of this assignment is for you to confront at least a few of the issues faced in addressing thetradeoffs between urban form, land use and transportation prior to us trying to do it for real for all of NewJersey. You are to work cooperatively with the members of your group. It is your job to layout the land use plan of your city (please give it a name) which has the followingfundamental characteristics (which you may augment ONLY if you can justify the change to me!):1. City boundary is square with sides 10.119 miles long. (total area 102.4 square miles)2. A river runs through the city (you locate it)3. There are several lakes, and planned open space areas. One lake is about 1.6 sq. mi. others are about0.5 sq. mi. Open space is appropriately sized so that in total, about 30% of the space is totallyundeveloped.4. You shall use a Quad-tree approach to developing your traffic assignment (and land use) zones. ThisQuad tree will be up to a depth of 5 allowing for up to 1024 zones, the smallest of which is 0.316 x0.316 miles = 0.1sq. mi.5. Of course you aren’t expected to maintain land use data at the maximum depth throughout the entirecity. In the dense urban centers (of which there exists 2 or 3 (your choice)) you do want data at thehighest detail. In the outlying areas you can have a greater spatial aggregation. You may aggregateover areas that have contiguous land uses. For example, if you have large areas of open space, theycan be aggregated into one zone. Similarly for large suburban residential areas, or industrial tracts.In all you should maintain about 60 individual zones covering your entire area of which about 10should be vacant land uses that encompass your river, lakes, and undeveloped open passive space(This does not include recreational areas that attract patrons.). Each zone is Rectangular!! 6. Your 50 or so developed areas will range in size depending on the depth of the Quad-tree. 7. For each one you will need to specify the amount of each type of land use that it contains. You willmaintain these data in the form of an array (spread sheet). Elements of this array include:Quad-tree designation ( a sequence of up to 5 numbers each having a range of 1-4). For example231 is the 1st quadrant of the 3rd quadrant of the 1st major quadrant. So if you decide to call thelower left quadrant the 1st and proceed counter clockwise, then this is the lower left of the upperright of the lower left quadrant!Leave room for x and y coordinates for the centroid of each zone.Area of the zone (depth 5 zones have areas of 0.1 sq. mi., depth 4 zones are 4 times as large, etc.)# of residential units (which must be converted into total population (also function of residentialdensity), number of workers, number of school aged children, number home workers)School enrollmentRetail floor spaceRestaurant floor spaceOffice floor space (converted into # of employees)Industrial floor space (converted into # of employees)Recreational activity space, by type (golf course, movie theater, sports stadium, etc)8. Your city is self sufficient! This means that there is employment for all that work, there is schoolingfor all children, there is restaurant space for all that eat out, there is recreational space for allrecreational activity. There is a balance! Thus, you are going to have to juggle the numbers aroundor make one zone the balancing zone! 9. Let’s try for a population of about 250,000, with some central zones having populations of as much as40,000 people per square mile. Your residential zones should have populations of 4,000 – 10,000.Some 40 or so zones should include residential land use. Other land uses should be morePage 1 of 2 01/13/19 Orf 467 Fall 2002/3concentrated in fewer zones, although many residential zones will also include some non-residentialland use. Anyway, it’s your design! You make the call. Due: Wednesday Oct 1010. The next objective is to estimate the number of trips, by type (and time of day) that a re produced andattracted by this development.10a. Each group is responsible for generating the a trip matrix for each one of the following 4 trippurposes: a. Home-based work, b. Home-based Shopping/eating/recreation c. Home-basedSchool and d. non-home base trips. To make this a little easier, we will assume that the non-home based trips have productions areproduced and attracted in all but residential areas. Their attraction rates will be one-half of theirattraction rates for home based trips and they will have production rates that are equal to theattraction rates. Because each zone will have an equal number of P and A there will tend to be alarge number of intra-zonal trips. This is somewhat realistic because linked trips tend to beshorter (you are more likely to grab beer at a watering hole that is very near where you workbefore you go home.!?10b. Estimate total daily person trip miles for each trip type and total for your city. To simplifythe computation use (1.2 x straight line distance) as the distance between zone centroids andapply that to each trip Due: Wednesday Oct 24Page 2 of 2 01/13/19 Alain L.
