User-friendly transit isochrone generator powered by OpenTripPlanner

DCP travelshed generator

A frontend tool for creation,display, and export of OpenTripPlanner isochrones in New York City

Available at nycplanning.github.io/travelsheds

Backend: An OpenTripPlanner server using data from OSM MetroExtracts for NYC, and GTFS Data for the New York City Subway. (More modes coming later)

Technologies: -MapboxGL.js for the web map -React.js for the cutoff selector UI component -CARTO for the subway lines raster tileset -Bootstrap, JQuery, Mustache

labs-travelsheds's Issues

.prj file not working properly

Issues with the manually-added prj mean that ArcMap still requires the user to select a CRS.

Add ability to search for an address and use search result as travel starting point

Add timeout for API Call

The site shows "building travelsheds" when the API call is initiated but if it errors or takes too long, there should be some kind of "oops, something went wrong" message displayed to the user.

Cannot click within isochrones

Driving doesn't work

Add reset or clear map button

Weird spikes on isochrones

What could be causing these irregular shapes, especially in 5-minute walking isochrones? On a grid like Manhattan's we should expect to see pretty regular shapes, but they seem to become less regular when doing a cutoff of 5 minutes.

Question posed to OTP community here

Flagging that I'm archiving this

@rtblair Just flagging that I'm archiving this because, well, I didn't know it existed at some point. The gh pages link 404s so I'm assuming it's safe to assume it's archivable

Add additional transit networks

Let's go beyond NYC Subways on the OTP Server.

Some quick wins:
-NJ Transit Commuter buses and trains
-PATH trains
-MTA Buses

If the last time cutoff is blank a travelshed will not be generated

appropriate transit layer for travel mode map context

it would be great when travel modes are selected, the appropriate transportation network shows. For example, bike travel mode should trigger the bike route layer and remove subway transit.

Issue to add labels

Add a Splash Screen

Maybe we should lead with a bit of text to let the user know what this is all about.

Downloaded Shapefile does not import to Carto

The GeoJSON imports correctly, but the SHP throws an error.

After deleting the .prj that is added to the zip by mapshaper, it imports correctly into carto

Add BETA Badge

Add a BETA Badge to the page until the product is developed further and ready for release

Add a Splash Screen

Maybe we should lead with a bit of text to let the user know what this is all about.

Sidebar does not scroll when there is overflow content

If you keep adding time cutoffs, content in the sidebar will get long and may extend beyond the viewable area. We should add overflow-y: scroll so it can be as long as it needs to be and the user can still access the download buttons.

Add Staten Island Railway

Can you please add the line for the Staten Island Railway as a layer in the map? It seems to be including the SIR in the subway travel data.

Thanks!

Add spinner to show something is happening

Some script references blocked within NYC domains

Hi - this thing is awesome, but the following script references are being blocked (on DOHMH network) because they are pointing at the blocked Facebook domain:

<script src="https://fb.me/react-15.0.0.js"></script>

<script src="https://fb.me/react-dom-15.0.0.js"></script>

... result is that in the app your almost instant travelshed generation appears to take forever (never completes)

Add population data and administrative boundaries

From Rudy in GSS:

If it is possible, I think it would be quite useful if a user of Travelshed could bring in an Administrative or Political district layer? The ability to include these districts could allow user to determine how many people live within a particular district that are within a certain distance of a proposed facility such as a school, senior center, etc. and other service provider.

We have wanted to add population data for a while now. Doing so will require some server-side resources, as we would need to be able to do a spatial query on the travelsheds. I would propose abstracting the OTP server behind a custom API which will talk to both OTP and a PostGIS database that has the census/population data and admin boundaries.

One api call would return the travelshed geometries as geojson with a properties object containing things like:

totalpop2010:
projectedpop2020:

etc

it could also break down in to census tracts/ntas, with counts for each.
