REGIONAL STRATEGY PROJECT

MIDWEST CITY STUDY LOCATION Chicago, IL DATE 2018 SCALE Midwest Region MY ROLE Lead urban planner

This research project identified and analyzed major population and lifestyle trends that impact urban development in the Midwest region of the U.S. The study revealed three macro trends within the region: a shifting population, challenges of de-industrialization, an increase in connectivity and demands for life quality. While migration to the nation’s urban city centers remains a defining micro trend, Midwest cities continue to lose population as people relocate to South and both coasts. The research was a high level overview that help the team evaluate the impact of its current project works within the broader context of the region, and make effective strategies for future opportunities.

WORKPLACE RESEARCH PROJECT

WORKPLACE FOR COMMUTERS LOCATION Philadelphia DATE 2017 SCALE Philadelphia Metropolitan MY ROLE Lead urban planner

In 2017, a client considered to add a new regional office to help shorten employees’ daily commute distance. These employees are currently based in 3 major and 12 other offices. Based on a comprehensive list of current employees’ home zipcode and their current work locations, the study quantified the total number of employees who reduced commute distance, and the total distance of mileage saved. This research helped the client to decide which new location can best benefit employees.

ASSUMPTIONS • Zipcode boundaries are based on TIGER/Line Shapefile, 2015, 2010 nation, U.S., 2010 Census 5-Digit ZIP Code Tabulation Area (ZCTA5) National • For all employees, commute start point are based on the center of each Zipcode district centroid. • 99.5% people who commute drive cars. All commute distance is calculated by straight lines (from zipcode centroid to workplace point), not specific driving route.

2. VISUALIZE THE DISTANCE DIFFERENCE • For the 1643 Spring House based employees, re-calculate the direct distance from home zipcode address to Spring house, home to Fort Washington and to Depuy West Chester. And repeat the same process for 807 Horsham based employees, 841 Malvern based employees and 118 other place based employees. • By visualizing the commute pattern it can be noticed that, for each individual employee, the wider angles, the more different from their original direction. The closer to the centroid of all homes, the better for employees on average.

3. BENEFITS COMPARISON If Depuy West Chester is chosen as the additional workplace, 804 of the total 3,409 employees would be able to shorten their commute distance. • The 435 employees who currently based in Spring House can save 12.2 miles on average. • Employees who based in Horsham, their average saved commute mileage is the highest. • The 229 Malvern based employees didn’t shorten their commute distance significantly.

EXISTING

• Fort Washington option can benefit the largest group of employees, which can help as many as 1,330 employees shorten their commute distance. • However, Fort Washington is very close existing offices Spring House and Horsham that people who already work here would not necessary relocate to save a few miles due to operational efficiency. • Depuy can help 804 employees to save their commute distance with a total mileage of 7,710. It can help capture employees who commute from southwest to Spring House or Horsham.

• Further comparison for locations will need to include operational management factor at a departmental scale.

PUBLIC REALM RESEARCH PROJECT

USING GIS TO MEASURE THE QUALITY OF URBAN PUBLIC SPACE LOCATION City of Chicago DATE 2016 SCALE City MY ROLE Lead urban planner

This project aims at providing designers an intelligent tool working through a process to decompose urban design terms into factors that can quantitatively measure how good a public space is, analyze them, and construct a new grading system with these new usable indicators. Currently, lacking of effective and objective measurement for quality of urban public space has prevented collaboration between urban public space design and geographic information system. Urban designers usually use perceptual terms when describing and assessing a place. Public urban spaces in the city of Chicago are selected as a sample for tool-building and demonstration. The product can be applied in the real world for three purpose: case study, preliminary site analysis and design decision-making.

ABSTRACT Lack of effective and objective measurement for quality of urban public space has prevented collaboration between urban public space design and geographic information system (GIS). Urban designers usually use perceptual terms when describing and assessing a place. The current project aims at providing designers an intelligent tool working through a process to decompose these urban design terms into factors that can quantitatively measure how good a public space is, then analyze them, and construct a new grading system with these new usable indicators. The indicators included in this project are land use, demographics, neighborhood, transit network, retail and space feature. Public urban spaces in the city of Chicago are selected as a sample for tool-building and demonstration. The product can be applied in the real world for three purpose: case study, preliminary site analysis and design decision-making.

CONTEXT With the world’s population growth and cities urbanization, people who live in the urban area care more about the space quality that they live in every day. As urban designers or planners, we always try to find a way to make our cities more livable and attractive. Perceptually, public spaces are usually seen as an influential urban feature in evaluating the city’s living quality. Many of them are geographically located at a dominant place in the city, while either historically or culturally remarkable. So the success or failure of these public spaces matters a lot to the life quality of local neighborhoods. Urban designers has been exploring the ways of how to effectively assess a public space for some time. Among the methods, Kevin Lynch’s <The Image of City> reveals one of the most famous one--by survey. The book presented some results of how observers take in information of the city. He reported that users understood their surrounding in consistent and predictable ways, and then forming mental maps, which are mostly consisted of five basic elements—paths, edge, district, node and landmark. However, surveys and analysis by designers are more based on an instinctive and perceptual way of evaluation, thus they have limitations to some extent. Firstly, they are helpful for describing the overall qualities of a space that whether it is comfortable, appealing, intriguing and memorable or not, but people may not think about which elements really make this place work. Secondly, surveys usually take long time to get effective and enough feedback. Urban design projects are usually time intensive or of large scale, it is unfeasible to take surveys every time in depth. So in order to have a better understanding of the rational reasons which contributed to the success of a public space, urban designers need a quantitative tool for measurement.

18


This project is an individual research project aiming at exploring how Geographic information system can be effectively used in design realm. Inspired by the design and case study works from Public Realm Studio, the quality of public space is crucial to a city since successful public spaces can add great value to adjacent properties and to the city. Through the Advanced Topics in GIS class, a refined model to better scale the quality of an urban public space was developed.

PURPOSE The research proposed a way of evaluating public spaces by using multiple measures that could be quantified by GIS. Since the tool is created for urban designers, first of all, find out the key perceptual words that designers would consider to use in describing or assessing a public space. Secondly, check out each term that how physical factors can be decomposed from the general terms. In the process, GIS database will provide these basic factors like physical forms, socio-economic and environmental feature. Thirdly, analyze the decomposed factors, and use regression method to test which factors can be used as effective indicators. By integrating all customized indicators, we can construct a grading system used for quantify the space quality. This method could be used for case analysis, and in design process, it could be used as tool for site evaluation, alternative plans design and test, and decision-makings.

19


APPROACH: 1. Term translation There are 5 categories for indicators that we will potentially use in the measurement. Below Land Use Mix—Land Use—Vacancy, mix of land use. People—Demographics —Neighborhood density, education attainment, household income, and age.
 Accessibility—Transit network—including metro stations, bus stations, and transfer stations, bicycle network, and pedestrians. Proximity to energy and resource—Retail—Healthy food density and accessibility which includes fresh grocers and farmers markets, cafes, restaurants and shopping. Space quality—Space feature—Enclosure, imageability, building condition, block, street or building scale, attractiveness.

2. Data preparation After we translate perceptual terms into all fundamental factors for measurement in urban design realm, we need to see if these elements could be found from GIS database or collected from other sources. Below is a summary table that describes how each raw data from GIS database will be used and translated into urban design language. In this step, data interpolation only means the preliminary decompose, converting and recompose.

3. Data analysis After all potential factors prepared, the second stage is to analyze each of their relevance to the quality of urban public space. So regression will help us in identifying the degree of relevance and the likely weight for each of the factor. Firstly, dependent variable y should be well selected. In this study, park scores based on Google reviews will be chosen as a scale of people’s opinion upon the quality of the space. There are two reasons for that: Firstly, the study aims at building a bridge between perceptual assessment and objective factors. Secondly, urban public space is used for serving people who live in an urban life, so people themselves are the best scale to assess the quality. In this step, I selected parks which have more than 5 people’s grades for it, and these places include civic parks, community parks and neighborhood parks. The score range is among 0-5, based on people’s average review grade. Since the precision is only 1 decimal figure, I re-scaled the range into 0-20 so that the regression result can be more reasonable.

Y DEPENDENT VARIABLE

Park score

Park buffer

Secondly, for each independent variables x, the data in park’s buffer area are selected. To achieve that, region group should be applied to all parks so that each of them will become an individual island. Then use zonal statistics to create a buffer area for the park. In this dataset, grid cell’s size is 30m*30m, which means 15 cells’ buffer can simply cover 2-3 blocks away from each study park. After that, apply zonal statistics to calculate the factor’s mean value, or variety value, or minimum value based on factor features. Therefore, each park has a series of data from different factors for the preparation of regression. 22

What needs to point out is the last category, space quality data. For enclosure, in this regression analysis, the ratio between ‘surrounding average building height’ and ‘park area’ is used to measure the enclosure feeling. However, in individual cases, a better way to depict enclosure is to use viewshed function in Arc Toolbox. Firstly, build a tin layer based on selected buildings height information. Then convert the tin layer to raster file, and reclassify the layer to make the building topology sharper, in order to depict viewshed more accurate. And same steps to adjacent trees and other vegetation. Finally choose an appropriate point where people usually clustered, and apply viewshed to generate a sight layer for this public space. This method is not applicable here is because, model builder can never select a single point for all places. Imageability is based on the distance to city’s important assets and landmarks. And attractiveness is based on the number and distance to public arts. Historic or modernity feeling is based building’s age.

RESULTS Sampling function in GIS is applied to collect each park’s data. Each park’s score together with its series of independent variables are used to build up a regression model in IBM SPSS. In this case, multiple regression is one of a good analysis type. This is because, firstly, the model is based on multiple variables and the research is to explore the relationship between the people’s assessment to a public space and all other objective factors. Secondly, multiple regression allows people to determine the overall goodness of fit, and the relative contribution of each of the predictors to the total variance explained, which means the ‘relative contribution’ of each independent variable can be generated. The assumption made to run this regression is, dependent variable should be measured on a continuous scale rather than an ordinal scale. Below table is a part of the original data entered into the regression software. Next step is to interpret data from the regression result. The R represents the multiple correlation coefficient, while R square represents the proportion of variance in the dependent variable that can be explained by the independent variables. In this case, R is 0.736, indicating a good level of prediction; and R square is 0.541, meaning that our independent variables can explain 54.1% of the variability of the dependent variable.

Y predicted=B1*X1+B2*X2+…..Bn*Xn For example, for every unit increased in poverty ratio, we expect a -0.5 unit decrease in the park review score, holding all other variables constant. Similarly, for every unit increase in the variety of zoning types, we can expect a 1.194 unit increase in park score. For t and Sig. columns, they are the t-stat and their associated p-values used in testing whether a given coefficient is significantly different from zero. Usually a p-value smaller than 0.05 indicates the factor is significantly different from 0. In this result table, only ‘Building Height’ factor is over 0.05. So this factor is proved to be not statistically significant so that should be removed. In conclusion, in terms of the data collected, variety of zoning types, distance to bike routes, distance to CTA Stations, all of which have a positive effect to the quality of parks. While population density, poverty ratio, building ages have a negative coefficient to the Y variable. Chart below is a correlation analysis between poverty ratio and park score.

DISCUSSION Though the regression result show that the model is of a good fitness. However, in the research process, there are still a lot of issues that are unable to be well solved and lead to some deficiencies of the model. Firstly, lacking of enough sampling data. Since the park review score are based on Google, some famous and big parks usually get a large number of reviewers contributing to the assessment. Theoretically, the larger number of reviewers, the better results can be obtained. However, there are still a lot of small neighborhood parks lacking of effective scores from enough reviewers. Therefore, to improve this model, getting more samples should be one of the most important aspects. Secondly, due to the different size of parks, bigger parks usually get more samples in data collecting, thus have more influence to the final regression result. In City of Chicago, this problem would not cause too much imprecision because selected parks are all from the city area, which means usually the bigger park it is, the more influence it will have on the city. However, assuming another city possess a very big riverfront park in rural area, and it works as only a protection or a buffer to the river, rather than contributing to people’s urban life, we have to customize the model then. Thirdly, there are still some perceptual terms cannot be well translated. For example, enclosure is actually an important concept in urban design realm. However, purely using building height is not enough to depict this factor. As mentioned above, viewshed should be more appropriate to describe this term, but this function is better applied in a single public space assessment, there are limitations for the citywide scale.

PRACTICE AND APPLICATION The grading system can be applied in urban design and planning realm, as an important tool that used for measuring the quality of a public space. The first application is to evaluate existing open space and public space, learn lessons from the correlations between indicators and success, and explore potential development in the future. Below is an example of how the grading system applied in Millennium Park. In this case, viewshed function is applied. Secondly, it could be used for preliminary site analysis, discovering site strengths, deficiencies, opportunities and challenge for design. Since design projects usually have a short term, this tool will help designers learn the site in a quick but accurate way. Thirdly, in design process, the method could be used for scheme comparison and decision-making. In competitions and project bidding, the method could also be used as a measurement that probably is more convincing.

UPENN FOOD TRUCKS ON SNOW DAY By given the assumption that people at Penn generally walk at a speed of 5 feet per second on Hard Surface conditions but only half as fast over Green Space and 1/10 as fast when walking in the Street, while Buildings and Water are impassible. Because of a recent snowstorm, all speeds were changed to 13 1/3 feet per second. Given the 3 lunch trucks and 40 typical customers, we will determine how this new condition will affect trucks, customers, and landscape in between them. Q1: How many customers will be gained or lost in a snowstorm for each truck?

Before

After

1. Create two friction grids for the campus condition of before after snow. Reclassify the original layer, set the categories as seconds per foot taken to the food truck. 2. Use focal statistics (maximum) to enlarge the pixels which represent the customers and food trucks. Then region group the food truck only layer.

3. Apply cost allocation for both layers of before and after snow to see which customers are in each of the truck's zone.

4. Use zonal statistics (sum) to count the customers in each zone.Generate how many customers each truck gain or lost due to the snow.

Value

34

-2 -1 3

5. Results: The southwest truck gained two customers. The north truck gained one customers. The southeast truck lost three customers.


Q2: How much travel time will be saved or lost due to the snow? Before

After

1. Began with the before and after snow layer, perform cost distance to the truck only layer as the source data, and the friction layer as input cost data. Then generate how long time customers will cost in both before and after snow maps. 2. The length of time that customers saved or lost will be calculated by substract the before snow layer from the after snow layer. Negative values means times saved, and vice versa.

Q3: How many more or less customers will be traversing on the pixel on their way to lunch? Before

After

1. Started with the time cost layer, generated two before and after snow layers via flow direction.

2. Then apply flow accumulation to visualize the customer paths to the food trucks. Finally, substract the before-paths from afterpaths by raster calculator. Negative values means less customers will choose the paths, and vice versa.
