Divvy Bikes Outside Smoke Daddy

This is an analysis of the station use for Divvy bike-share stations in the Wicker Park and Bucktown neighborhoods (they blend together and it’s hard to know if the club or bar you’re going to is one neighborhood or the other).

Numbers represent a discrete trip, from one station to another (or the same station if the trip was greater than 3 minutes, to eliminate “hiccups” where the bike left the dock but didn’t actually go anywhere). Customer means someone who used a 24-hour pass and subscribers are annual members. Gender is self-reported on a member’s DivvyBikes.com user profile.

17 stations listed.

Metra) and North/Wood stations.

Based on the popularity of the Ashland/Armitage station, which is right outside the Clybourn Metra station – a very popular train stop – I think there might be a residential service gap near Saint Mary of the Angels School. I recommend a Divvy station at Walsh Park this year because the Bloomingdale Trail will open and terminate there.

Notes

Not all of these stations were online when Divvy launched on June 28, 2013, but I haven’t yet looked into the history to see when each went online. Therefore direct comparisons are not appropriate until you have a trips per day number. Then, seasonality (very cold weather) has its own effect. At the very least, all stations were online by October 29th, with the final addition of the Lincoln Ave & Fullerton Ave (at Halsted) station.

Can someone use “R” to make a time series chart on the entire trips dataset so we can find the best cutoff time to eliminate “hiccups”?

Query used: SELECT count(`trip_id`), usertype, gender FROM `divvy_trips_distances` WHERE (start_station = ‘Claremont Ave & Hirsch St’ or end_station = ‘Claremont Ave & Hirsch St’) AND seconds > 180 GROUP BY `usertype`, gender

Mapping a campground that doesn’t exist: a before and after view of OpenStreetMap

December 27, 2013 / / 8 Comments

Pretty soon there will be a campground shown in OpenStreetMap, and added to its geocoding database, when I’m done adding it.

I temporarily become addicted to mapping places on OpenStreetMap. In my quest to find and map all campgrounds in Chicagoland – in order to publish them in the Chicago Bike Guide – I came across a campground that was constructed this year and opened in August 2013. This is the story of figuring out how to map the Big Rock Forest Preserve campground in Big Rock, Illinois.

I found on the Kane County Forest Preserve District website that the organization operated a campground at Big Rock Forest Preserve. I couldn’t locate the campground in Google Maps by the address the website gave. I couldn’t find it in OpenStreetMap, either, because no one had mapped it, but it’s there now.

When I searched for the park by name, Google Maps zoomed me to the main entrance of the park, but I still couldn’t see a campground. I downloaded the forest preserve district’s park map (always as a PDF) and followed the roads in Google Maps until I came across the campgrounds approximate position. There was a new road here so I followed that to find a campground under construction.

Google Maps shows the campground and artificial lake under construction.

Google’s imagery of the under-construction campground was taken on May 23, 2013 (get the date from Google Earth). This was great because now I could open JOSM, a powerful desktop OpenStreetMap editor, and locate the site, load Bing’s imagery and start tracing the campground to upload to OSM.

Bing’s imagery in JOSM, the OpenStreetMap-editing app, doesn’t show the campground.

The problem was that Bing’s imagery – and this is typical – was outdated. I could easily compare the imagery side-by-side and based on other landscape features (like the forest edge) guess where to trace the campground, but OSM needs better quality data. Enter MapWarper.

Compiling and mapping Chicago-area campgrounds

December 26, 2013 / / 0 Comments

I’m adding Chicago-area campgrounds to the Chicago Bike Guide to entice new users and to espouse the enjoyment of medium-distance bike camping (which I’ve now done officially once, earlier this year).

<The Chicago Bike Guide is available for Android and iOS.>

I’m taking a systematic approach to finding all the publicly-owned campgrounds in the area by looking at primary sources.

First, though, I’ve used Overpass Turbo to create a list of all existing campgrounds in OpenStreetMap. You can see a gist of these places.

Camp sites at Greene Valley forest preserve I mapped.

Camp sites at Greene Valley forest preserve I mapped.

The next method is to find out which campgrounds are operated by the county forest preserves, which are usually well-documented on their respective websites. Then I will look at state parks in Illinois, Indiana, and Wisconsin, operated by states’ respective Departments of Natural Resources (DNR). Next I will look at national parks and finally commercial campgrounds.

The app will display campground information such as alcohol rules, if cabins or lodging is available, and how you can get there (which trails or train lines).

I’ve so far mapped the campgrounds in two ways, as nodes and as areas. At the Greene Valley forest preserve in DuPage County, for example, I’ve mapped the 11 individual camp sites (see map), but at Blackwell forest preserve in the same county, I’ve mapped the area as the camp site (see map).

Blackwell has over 50 sites in a discrete area and it’s more efficient to map them as a single node, while Greene Valley had far fewer sites but scattered over a couple areas.

Stop locking your bike at the Clybourn Metra station overnight

Existing bike parking at the Clybourn Metra station

This is a resolution.

WHEREAS, I love GIS.

WHEREAS, I was reading this blog post on the Azavea company blog about bike theft prediction and trends in Philadelphia.

WHEREAS, I analyzed bike theft location in Chicago in 2012 and the Clybourn Metra station emerged as the most frequent Metra theft location.

WHEREAS, I searched the Chicago Stolen Bike Registry for “clybourn” and several thefts have been reported to the registry in 2013.

WHEREAS, I believe the Chicago Police Department still doesn’t allow searching of their database for bike thefts thus leaving the CSBR as the premier source of data.

WHEREAS, I am watching this show called The Bletchley Circle wherein a group of four fictional women who cracked codes in World War II are solving a murder mystery in 1950s London.

BE IT RESOLVED that you should not leave your bicycle parked at the Clybourn Metra station overnight as it is a terrible place to leave a bicycle parked. Why? No one is around most of the time to socially secure your bicycle.

New bike parking at the Clybourn Metra station

This is a great place to get your bike stolen. In the dark. Overnight. With no one around to see it happen. 

NIMBYs can’t have it all: Student instructor at West Town Bikes supports wheel-friendly park

August 15, 2013 / / 0 Comments

Lebster, far left, three students at West Town Bikes, and executive director Alex Wilson, head to Open Streets on State Street. 

Update August 27:  Lebster was interviewed by RedEye reporter Leonor Vivanco today.

Lebster Pabon, an instructor at West Town Bikes in Humboldt Park (it used to be in West Town!), attended an important Chicago Park District board meeting yesterday and brought one of his high school students and that student’s mother. They spoke up to support what would be the city’s first wheel-friendly park, where people can skate, bike, and… which would be new to Chicago… use wheelchairs in the park. Neighbors of the Bloomingdale Trail were in attendance to oppose the park.

Lebster called me to say that another attendee spoke up to say he would like to bring his grandchildren to such a park, and that a board member added he has to take his kids out of Chicago to use bikes in a park like this. Lebster mentioned that since it’s at the end of the Bloomingdale Trail it would be very accessible: ride up Rockwell from West Town Bikes, a low-traffic “side street”, hop on the Bloomingdale Trail, and ride 10 minutes over to Walsh Park. When asked if the park would attract people from other suburbs, Lebster said it would attract people from around the country because it could host events.

Finally, a Chicago Park District board member asked if bikers and skaters coexist. Lebster told me he said, “Yes, the culture is very disciplined in skate parks”. I’ve witnessed it myself and I didn’t expect it, imagining that teenagers are unruly. Rules aren’t needed, though, as each person has learned to take a turn in the park and then respect the time and talent of the other skate park users.

This is a very special and unique moment for young Chicagoans who are active outside as this proposed park would be the first to accommodate bicycles and wheelchairs. The Chicago Park District’s first core value is “Children first”. The website says, “Our most important task is to bring children and families into our parks and give them great reasons to stay and play for a lifetime”. Lebster’s contributions to the meetings, and the conversations around the park, were integral to that value and the District’s mission.

About West Town Bikes

West Town Bikes and I have a good history. I came into contact with the organization in 2006, the year I moved to Chicago. I joined a scavenger hunt in October that ended at the shop. I met a lot of people there that have shaped my bicycle advocacy future, including Kevin Monahan, who put John Greenfield and I together after which we started Grid Chicago, Jim Freeman, Kevin Conway, Gin Kilgore, and countless other people. West Town Bikes is also the host and a sponsor of my annual Cargo Bike Roll Call events.
