Quantitative School Bus Stop Risk Assessment of Redlands, California



This was a Major Individual Project for the University of Redlands working with Claiborn Lewis Phillips in 2005.



















The purpose of this Major Individual Project (MIP) was to identify public school bus
stops in the city of Redlands with certain risks. Those risks being violent crimes, drug
related crimes and the homes of convicted sex offenders. The MIP made use of the
Kernel density function along with the Getis-Ord Hotspot function in ESRI’s ArcGIS 9.1
software. These functions were both used alone and combined. The Kernel Density
function was used alone to derive a density surface that would be reclassified to produce
a risk surface that would identify the risk of the school bus stops. The Hot Spot Analysis
(Getis-Ord Gi*) with and without (z-score) Rendering were use in combination with the
Kernel Density function. The pairing of these two functions, Kernel density and Hot
Spot Analysis, was utilized to produce surfaces that would act as visual aids to better
identify hot and cold spots. These surfaces were generated by using the Hot Spot
Analysis functions to compute the Getis-Ord Gi* (with and without rendering) values.
Those values were then used as the Population field for the Kernel density function that
produced Hot Spot/Kernel density surface. These results were used to produce maps to
aid police officers, and school officials and produce an IMS site to inform the parents of
the community.

Using GIS to Manage the Redlands Bicycle Classic


This is Marilyn Dreuker's MSGIS Major Individual Project from 2003.

For 19 years, the City of Redlands has been hosting the Redlands Bicycle
Classic which is considered one of the most fun races in the U. S. by some
cyclists. This national event has endured longer than any other cycling event in
the U. S. For 6 days, this professional cyclistsí race takes place not only in
Redlands, but also in the cities of Riverside, Highland, and Yucaipa. The race in
April 2003 had almost 250 riders covering a total distance of approximately 348
miles for the menís races and 280 miles for the womenís races. There were nearly
1000 volunteers and an estimate of 50,000 spectators. (Oberjuerge 2003).
There is no question that credit for the raceís success has to be given to the
race committee, made up of the Redlandsí community and the police department.
Their well-organized efforts to run things smoothly makes the race enjoyable for
everyone. But to plan such a big event as the Bicycle Classic, especially
managing the number of people involved and the associated problems, takes a
great deal of time and effort. Everyone would benefit if there is a more efficient,
easier way to manage security, spectators, traffic, and road closures when planning
for this type of event.
This project addresses a better way to solve this planning problem by using
GIS to integrate the data, visually display the information on maps and perform
visual and spatial analysis of the integrated data sets. Using GIS, the police
department can improve the effectiveness of the planning by displaying the
integrated data on a map to see where problems have occurred or are likely to
occur. Visual or spatial analysis can help with planning the logistics of the event,
planning for security and medical emergencies, easing traffic problems, and
maintaining order.
This report communicates how GIS can be used as a tool to help with the
planning and implementation tasks. It begins by looking at other GIS applications
that relate to this activity. It then provides a concise look at the goals, scope and
objectives of this project and specifies the design, development and analysis that
were taken to address the issues. The report contains the products that will be
delivered to the client ñ the Redlands Police Department. Finally, conclusions and
recommendations for further study are provided.

GIS Project Proposal #2 MSGIS


Why do this project?
The City of Redlands is an average-sized city that is rapidly becoming a representative example of ESRI’s market base. For this reason, Redlands stands to be the model city for the adoption of GIS technology. GIS has been a part of the police department’s regular business process since the mid 90’s, and there are two crime analysts and a database technician that will be available to facilitate your success with this project.

The City of Redlands holds an enterprise GIS license and is also a user of the Omega Group’s CrimeView, one of ESRI’s most active business partners. There is an explicit need for this project, and there is a culture of acceptance and data sharing with the Redlands Police Department and the City of Redlands. Here is your chance to work with an emerging field of GIS.

There are two very attractive features to partnering with us:
1. We are close enough to meet with frequently.
2. Your client has been through the U of Redlands MSGIS program, and understands what
the MIP process entails. Scope creep will be minimized and we’ll tailor your project to suit
your needs and interests.

20 Years of Crime
Crime analysis units work with pieces of data at a time.
Windows of time. Some procedures group incidents by the
most recent set of a week; some procedures compare one
month to the previous month; some compare 3 recent
months to the previous 3 months. This is a different
approach.

The Redlands Police Department has 20 years of geocoded crime
data, and there have been some changes over the
years. There are 2 sets of Census data available to correlate
values to (1990 and 2000). There may also be a possible
preliminary 2010 Census data set available.
Population has changed. Landuse has changed.
The infinite set of human variables are constantly changing what
is the effect?

Product
There is flexibility for what the data-product will entail.
The MIP and presentation will be the final deliverable, and
ideally we would like to see animations that depict the
changes that have occured over time. We can assist in the
development of these animations.
Support for your MIP will include regular access to our
network and our staff. For this reason, a light background
check will be necessary.

Wildfire Urban Interface UML


Renee has been working on a UML diagram to better understand how to model fire risk for her Major Individual Project at the University of Redlands MSGIS program. This is part of the conceptualization phase of the project, and this diagram helps to explain the relationship different entities have with each other. This phase helps her think through the process of geodatabase creation.

Disaster Mitigation Models for the City of Redlands

This is a Major Individual Project (MIP) project proposal by Renee Bousselaire from the University of Redlands MSGIS Program. We're glad to work with her, and will gradually add more content and rough examples of the models (with her permission) as they are developed.

Earthquake history shows that the southern San Andreas fault has earthquakes an average of once every one hundred and fifty years with a magnitude of 7.0 or greater. The last two major earthquakes on the southern San Andreas fault occurred in 1680 and 1812. Certain areas, close to San Bernardino County, are at risk because they have gone the longest without major earthquake activity (Jones, et al. 2008). Earthquake modeling has been conducted at the federal and state level for California, but the City of Redlands requires analysis at the city level. This project will demonstrate how ArcGIS spatial operators, ModelBuilder, and network functions can aid in disaster mitigation efforts for the City of Redlands, California. Based on predefined water pipeline breaks, the water response model will use geometric network features and Network Analyst to combine water pipeline and transportation networks to model which valves need to be turned off and how long it will take responders to reach the valves. The fire behavior model will use ModelBuilder and a variety of spatial operators to assign risk values to fuel loads, weather, and topography to create an output layer identifying probable fire locations. The models will serve as an introductory component of a larger disaster plan for the City of Redlands
