A map of buildings designed by Frank Lloyd Wright in Oak Park

I would like to hear feedback on the design of this map I made for school. It shows the location of buildings in Oak Park, Illinois, by American architect Frank Lloyd Wright.

The map is accurate; the building listing is from Oak Park Tourist. Feel free to print out the map and go on your own walking tour!

I created this map based on data provided to me by my GIS for Planners class instructors. Also in the assignment they gave limited background on who is commissioning the map, who will use the map, and the information it should describe and display. As the class has progressed, the assignments have become more open ended.

However, in making maps, there are always certain elements you cannot do without. Map makers include a scale bar, north arrow, and source information so that their map appears trustworthy. A legend is most often required, but many times maps can be designed intuitively so that users do not require a legend. I have attempted to design this map like that: I excluded a legend. Map users should be able to discern that the black and gray lines represent streets and also that the larger map with the gray background is a zoomed in portion of the smaller map.

I have posted other maps to my Flickr that you can also browse, some I made because of assignments, and others for personal interest and practice.

Impacts of Intelligent Transportation System elements on bus operators

The assignment: “Describe the impact of the following ITS components on the bus operator.”

The class: Transportation Management

Background: Intelligent Transportation System (ITS) is the application of computers and electronics to vehicles, highway and transit systems to improve the efficiency, effectiveness and safety of the systems. Many elements of ITS are “behind the scenes” (like centralized dispatching or traffic monitoring), and others are “front line,” in view of the users or customers (like Bus Tracker/NextBus or paying a fare with a proximity card). Some of these elements will have an impact on the bus operator themselves. In this assignment I describe what those impacts are, organizing the short paper by each element and their intrinsic advantages and disadvantages.

The following Intelligent Transportation System components each have multiple advantages (A) and disadvantages (D) for the bus operator (driver).

  • In-Vehicle Automated Announcements
  • Transit Signal Priority
  • Security Cameras
  • Emergency Alarm
  • Centralized Dispatch
  • Internet “Bus Tracker”

In-Vehicle Automated Announcements

A: This component allows the operator to concentrate on driving the bus as well as the safety and comfort of the passengers. It may reduce the stress of the operator because they are no longer responsible for keeping track of the street names, activating the public address system, and announcing stops.

D: Some bus operators, particularly those who have been with the company for a long time and own embrace certain traditions, may feel this technology is a way to make their job obsolete. Some bus operators may feel it erodes the personal relationship bus operators have with their customers. Others may feel that announcing stops required a certain skill on which they could compare or compete with others; new bus operators won’t develop this skill or find alternate ways to develop customer relationships.

Transit Signal Priority (TSP)

A: This component can reduce the tedium of a bus operator’s job of accelerating and decelerating because the bus can sustain higher speeds and stop less often (at signals, but passenger stops) when it is given priority at traffic signals.

D: This component may eliminate the bus operator’s job. If the transit agency can operate fewer buses on a route with TSP at the same headways and level of passenger convenience, bus operators could be reassigned to other routes, or laid off completely. Operating a bus at a higher speed could increase the potential for traffic collisions without having time to adapt or appropriate training.

Security Cameras

A: Security cameras can help protect the bus operator in case of an on-board incident that harms them by either exonerating them, rewarding them for their exemplary behavior in handling the incident, or by assisting law enforcement and prosecutors in pursuing justice against the perpetrator.

D: Recordings may catch bus operators not performing as required and could be used against them in disciplinary proceedings.

Emergency Alarm

A: The emergency alarm has the capability of calling for help from the agency’s control center and from local law enforcement to come to the aid of the bus and operator. Depending on the simplicity of activating the alarm, this ITS component has the potential to speed aid to the bus operator and allow the operator to concentrate on the incident at hand instead of spending time communicating to the dispatcher; the incident could be crucial requiring the bus operator’s full attention.

D: Agency management may feel that the presence of an emergency alarm reduces the need for law enforcement or security patrols on buses while the bus operators would prefer to have a high level of security patrol to deter vandalism or potential criminal incidents that either harm the operator or their customers. To ensure this ITS component doesn’t influence an increase in crimes, the agency must base any decision about change in the level of law enforcement and security patrols on factual data and studies and collaborate with all parties (bus operators included) about recommendations or proposals.

Centralized Dispatch

A: This component provides a single point of communication, to and from which all messages will be sent. The bus operator will most likely communicate with a single person (or staff position) at the control center, who will be responsible for answering the operator’s questions en route, handling emergencies by calling the appropriate personnel, and ordering live route or operation changes.

D: The bus operator may have a poor relationship or lack camaraderie with their assigned dispatcher that might place a strain on the effective operation of the bus and the route. For example, the bus operator might not fully follow the dispatcher’s directions if there exists a mutual or one-sided distrust or dislike. However, this would most likely have a negative impact on the bus operator’s performance rating.

Internet “Bus Tracker”

A: The “Bus Tracker” system is based on automated vehicle location (AVL) technology, which includes a geographic positioning system (via satellite) to pinpoint the bus’s exact location. AVL can create a timeline of the bus’s travel and identify the times at which the bus stopped and started. The data from this timeline could be used as evidence to exonerate the bus operator in an incident in a situation where a customer or other person accuses the bus or its operator of doing something wrong.

D: The Bus Tracker could also be used against the bus operator by showing evidence that they did do something wrong. The timeline data (which would show schedule adherence and could identifying running ahead or behind) can be used as a measure of the operator’s work performance and serve as evidence in disciplinary proceedings. AVL could also determine if the bus operator took an unscheduled break or went off the route.

Additionally, I see a case where customers who follow and come to depend on the Bus Tracker website are influenced by their dependence to change their relationship with the bus operator or the transit agency. For example, if the Bus Tracker displays inaccurate time information (one time, or consistently), the customer may become upset with the bus operator (who would most like not be at fault for any delays or inaccurate time information) or the transit agency. Bus operators aren’t always equipped or trained mentally or physically to handle upset customers.

Do you have any other ideas about the impacts of these ITS elements on bus operators (drivers)?

Bike friendly neighborhoods, in Chicago and beyond

Local professional bike commuter and amateur racer Brian Morrissey has written a series of guides to Chicago neighborhoods with a particular bicycle friendliness.

Think of these great neighborhoods to visit on your bicycle (they have bike facilities, bike shops, and they’re especially easy to get to) and spend some time there eating good food. I consulted Brian on one of the neighborhoods, where I lived for two years. I’ve written about Pilsen on my blog several times (and here). Even without all the wonderful burritos and the friendliest bike shop, I’d still call it my favorite Chicago neighborhood.

Here’s the list of Brian’s guides to Chicago’s bike friendly neighborhoods:

What neighborhood should he write about next?

What makes a neighborhood bike friendly? Let’s find out!

First, we’ll ask the League of American Bicyclists. The LAB uses a rating system akin to LEED certification of green buildings. And cities want to achieve bike friendly status just as much as developers want to achieve “green” status. Bicycle friendly communities must be able to demonstrate achievement in the five “E” categories.

  • Engineering – Infrastructure, facilities, bikeways, bikeway network, and accommodation of cyclists on roads.
  • Education – Programs to teach bicyclists, motorists; availability of information and guides.
  • Encouragement – How the community promotes bicyclist; BMX track, velodrome, Bike to Work Week, wayfinding signs.
  • Enforcement – Connecting law enforcement, safety, and bicycling.
  • Evaluation & Planning – Data collection, program evaluation, bike plan, and how to improve.

Next we visit Bicycling magazine to learn how they consider the Best Cities for Cycling (full list). The editors’ criteria is not as transparent as LAB, but I’ll take a crack at decoding their articles.

  • Visibility – Bicycling wrote this about Portland, Oregon: Just hang out in a coffee shop and look out the window: Bikes and riders of all stripes are everywhere.
  • Facilities – Chicago made the list, “Still The Best:” Richard Daley…has ushered in a bicycle renaissance, with a growing network of bike lanes, a bike station with valet bike parking, showers and indoor bike racks.
  • Ambition – Bicycling commended Seattle for having the goal to “unseat Portland as the best U.S. city for cycling.” Their bike plan calls for expanding the bikeway network to 450 miles.
  • Culture – In San Francisco, a lawsuit brought bikeway construction to a halt, but Bicycling says “[t]he local bike culture has stood strong, and the number of cyclists increased by 15 percent last year alone.”
  • Education – Because of Boulder’s Safe Routes to School Program, at least “one school reports that 75 percent of its students now bike or walk to school.”

Finally, on our journey to find out what makes a community or neighborhood “bike friendly,” we come to me. I’ll tell you it’s a combination of the built environment (infrastructure) and its wider connections (bikeway network), as well as the residents who bike and don’t bike (like motorists).

  • Infrastructure – A city must build on-street and off-street bikeways that increase the perception of safety. (I was unable to find any conclusive studies that attribute the presence of bikeways to lower fatality and injury rates, but I didn’t find anything that reported the contrary is true, so that’s good.) Secondly, when you arrive to your destination, you should find secure bike parking.
  • Network – When you built on-street and off-street bikeways, you must ensure they connect to each other. It’s discouraging to come to the end of a bike lane when it doesn’t reach your destination or another segment of the bikeway network. A good network leads to important and popular destinations, like major work centers and schools. Bicycling is more prevalent in areas with colleges and universities, see Baltes report (PDF). Almost as important as creating a network is publishing information about your network – where does it go and what should I expect to see or find on my route? A paper bike map showing the locations of local bike shops, parks, and schools goes a long way to assuage nervous bicyclists.
  • People – Lick your finger and put it up to the air to test the attitudes of those around you and how they feel about bicyclists sharing the streets with pedestrians and motorists. Residents supporting or hampering positive change to make bicycling a common activity or transportation and improve the safety of bicyclists is the most important way to determine how “friendly” a community is to bicycles and their riders.

If you’re familiar with those neighborhoods in Brian’s guides, try to apply the criteria sets from League of American Bicyclists, Bicycling magazine, and myself and do your own analysis of the bike friendliness in those neighborhoods.

What do you think makes a community bicycle friendly?

Making cycling normal: Cycle chic movement

Making Cycling Normal is a three-part series about how to increase the rates of people riding their bikes for everyday trips. Increasing this rate, also called the “modal split” or bicycle’s “mode share,” is a common goal amongst bike plans in major cities around the United States. No city in the United States has a bike mode share higher than 5% of all trips, or even all trips to work, where the rate reaches 40% in some European cities.

Cycle chic is an internet-based movement to promote “normal” cycling. At the root of normal cycling is riding your bike in your everyday work, school, or wherever clothes. No lycra, spandex, or bringing a change of clothes. Some may say it’s bicycling in fashionable or elegant clothes, but the dress up concept is open to individual interpretation.

Cycle chic began with photographer Mikael Colville-Andersen’s website called Copenhagen Cycle Chic, a blog where he posts photos of bicyclists in the capital city of Denmark. The photos tend to be of women dressed in trendy and fashionable clothing. The goals are promoting the city of Copenhagen, and riding one’s bicycle is a completely normal activity and mode of transportation for any trip no matter its purpose (and the Danes ride their bikes in all weather, with the cycling rate apparently only dropping 20% through winter – see Mikael’s photo below).

Mikael travels around the world promoting cycling culture as part of a company called Copenhagenize Consulting and also as Danish individual. He also writes a blog called Copenhagenize where he discusses the issues prevalent to bicycle and motorist cultures.

The cycle chic blog model has been imitated by bicycling bloggers around the world. Amsterdamize does the job for that Netherlands city. There’s also Los Angeles, Chicago, London, and Moscow. Visit Los Angeles to find a list of plenty more cities. If you find your city, get to know your local Cycle Chic Ambassador. Check out this blog’s author (me) test riding a Dutch bike from a local retailer in some fashionable clothing at a party. A former coworker, Christy, inspired me to start adopting cycle chic.

I don’t think there’s a cycle chic blogger for Milwaukee, Wisconsin, yet, but I think this guy could start it up (sorry for the blur):

How will these blogs increase cycling rates?

The blogs and their authors promote cycling as something you can do without gear, special clothes, or a significant lifestyle change. In their own ways, and targeted to readers in their own cities, they discuss how people can incorporate bicycling into their lives where normally a bus, train, or car would transport them. They show that bicycling can be fashionable, popular, and not something that “other” people do.

However, this stylish promotion of cycling will only go so far. Bicycle trip rates will also increase when cycling is safer (part two of the Making Cycling Normal series) or when we educate people about bicycling (part three).

UPDATE: Dottie from Let’s Go Ride a Bike (Chicago’s local cycle chic blogger) has picked up on a similar topic, how to promote cycling (and part two), and Cyclelicious has reblogged the topic and Dottie’s article.

Google Maps and Earth is the poor man’s GIS

For over four years, Google’s geography products have become the most popular geographic information systems on the Earth (no, the earth). Google is now as much a platform of GIS for computers and users as ESRI, the number one GIS software maker.

To continue its corporate goal of organizing the world’s information, Google has made sure to also organize the world’s (and other realms) geographic information.

Google’s free tools and products manipulate, map, reproduce and analyze geographic information:

  • Maps – the simplest source of satellite imagery for the public, although Microsoft’s TerraServer was probably first
  • Street View
  • Transit – including travel directions for trips on Transit
  • Ocean
  • Earth desktop software – includes Moon, Mars, Sky
  • My Maps
  • Yellow pages-style business listings
  • Driving and Walking Directions – including automobile traffic overlay
  • Keyhole Markup Language (KML) – a file format based on XML that allows for the easy sharing and portability of data about locations. I wrote about it here.
  • Maps API – this allows developers to include maps in their own applications and websites as well as build features on top of maps

These applications now allow anyone in the world with an internet connection* and a computer to start thinking about the world and neighborhood in which they live in terms of space, distance, the environment, land use, and most important of all the relationships between real life places and these greater themes. But not only will these instruments influence the thinking of individuals and the groups to which they belong, but they will give people tools to create.

What have people created with Google’s GIS tools?

I created a map that shows the locations of open grated metal bridges on bikeways (featured in the bike map) in Chicago. This is important to bicyclists because open grated metal bridges can be hazardous to them, especially those with high centers of gravity or narrow tires on their bikes. Bicyclists will most often encounter these bridges on trips into and out of the Central Business District. This map will help bicyclists find routes that avoid these bridges. Precipitation exacerbates the danger, especially if it’s actively raining, or snow isn’t melting.

UPDATE 12-03-10: I was looking for information on an upcoming Chicago Cyclocross meet and I found a great example of using the tools Google has created for everyone. See a screenshot of the map below:

I’m posting this image to show how easy it is to create a map that tells a story. The story here is a guide on how to be a participant or spectator at the meet. It points out places where people can park, cannot park, and where the restrooms are in relation to parking or the race course. See the full map.

What have you created? Leave a comment below.

Evolution of Google’s GIS toolbox

I believe that Google will continue to expand its array of GIS-related applications, and also expand their existing ones. I would like to see them create new connections between the applications they’ve already created. For example:

  • Google can mimic the attribute table essential in desktop GIS software (like ESRI’s ArcGIS, qGIS, or GRASS) by integrating their Docs web application with My Maps. I want to save my information in a Google Docs spreadsheet (either inputted directly online or uploaded from my computer), then create a custom map and assign a location to each of the records in my spreadsheet. Then, using tools shared between Docs and My Maps, I can automate the creation of colored points and lines for the records based on categories or numbers in my spreadsheet, much like the classification and symbology tools of desktop GIS software. For example, on my “open grated metal bridges” custom map discussed above, I want to create a spreadsheet with a column that has a yes or no value to the question, “Is the bridge treated?” All records with “yes” will have green dots, and all “no” values will have blue dots.
  • The reverse situation could also be made possible by an integration between My Maps and Google Docs. Let’s say I’m a clerk at my church and I need to group the congregants into geographically close clusters for purposes of assigning community service work. I’ve inputted all of their addresses into My Maps and added a point for every house. There’re only 40 houses on the map and I can see see about 5 clusters (to keep it simple I won’t introduce arithmetic means of finding clusters). I use a selection lasso in My Maps and select the points in my first cluster. Using a new Classify function I label these points part of Cluster 1 and color them purple – I also assign Cluster 1 to work at the nearest park. I continue for the remaining four clusters, assigning each cluster to help clean a different park. Once I’ve completed grouping the houses, I tell My Maps to generate for me a spreadsheet that lists the names and phone numbers and clean up time for all the congregants. Now I can quickly call everyone in Cluster 1 and give them their community service assignment which is convenient to where they live.
  • Google should open up its many data layers. Google has many data layers in its table of contents: They recently added real estate data, but they also have the locations of transit stations and bus stops (including timetables and route information), the addresses and phone numbers of businesses (like the Yellow Pages), as well as terrain in some cases and bike trails in others. If the data in these layers were open, map users could perform some basic analysis like counting the number of check cashing businesses within 1 mile for a study of banking behavior in low-income neighborhoods. Or a map users could find the gain in elevation on a bike trail over 4 miles to determine their ride’s difficulty. Another map user could use the transit information to calculate the level of bus service in a neighborhood by counting the number of stops available and the number of buses scheduled.

I’ll have to figure out a way Google can extract revenue from these features if I want to convince Google to produce them, but sometimes the company builds products and features before it figures out how to make money.
