Modifying speed data in OSM files

Living in rural Devon, we are surrounded by many roads that have a nominal speed limit of 60mph on which that would be a wholly inadvisable speed to travel, with likely speeds generally falling closer to the 20-40mph range.

For some journeys, this could have a significant impact when calculating the journey time using r5py and valhalla, which (presumably) assume free-flowing traffic at the maximum permitted speed for the road.

Tip

If you’re a bilingual R/Python user, you could choose to switch over to r5r at this point as they natively support modifying max car speeds, both at a granular level or applying a more general scaling factor to certain types of roads.

Trying this out

Let’s now show the impact of this change. First, let’s do the calculation on the unedited file.

Generating origins and destinations in the expected format

Let’s just calculate a single route we know covers a lot of minor roads.

Travelling from Cullompton to Cheriton Fitzpaine takes us along a large number of minor roads, so is a good test case.

Let’s travel from EX15 1HN to EX17 4JG.

origins = pd.DataFrame([{'id':'EX15 1HN', 'longitude': -3.3964515912457207, 'latitude': 50.85510704952628},
                        ])

origins = geopandas.GeoDataFrame(
    origins,
    geometry = geopandas.points_from_xy(
        origins['longitude'],
        origins['latitude']
        ),
    crs = 'EPSG:4326'
    )

origins
id longitude latitude geometry
0 EX15 1HN -3.396452 50.855107 POINT (-3.39645 50.85511) 
destinations = pd.DataFrame([{'id':'EX17 4JG', 'longitude': -3.6102812023506217, 'latitude': 50.844712763862496},
                             {'id':'Exeter Airport', 'longitude': -3.413323770890914, 'latitude':50.73714162801647},
                             {'id': "Cornish Arms Tavistock", 'longitude': -4.146750479096123, 'latitude': 50.551448737522115}])

destinations = geopandas.GeoDataFrame(
    destinations,
    geometry = geopandas.points_from_xy(
        destinations['longitude'],
        destinations['latitude']
        ),
    crs = 'EPSG:4326'
    )

destinations
id longitude latitude geometry
0 EX17 4JG -3.610281 50.844713 POINT (-3.61028 50.84471)
1 Exeter Airport -3.413324 50.737142 POINT (-3.41332 50.73714)
2 Cornish Arms Tavistock -4.146750 50.551449 POINT (-4.14675 50.55145)

Routingpy

First, let’s calculate the travel for our unedited pbf file.

transport_network = r5py.TransportNetwork(
    "../../datasets/devon-260422.osm.pbf",
)

travel_time_matrix_car = r5py.TravelTimeMatrix(
    transport_network,
    origins=origins,
    destinations=destinations,
    transport_modes=[r5py.TransportMode.CAR]
    )
travel_time_matrix_car
from_id to_id travel_time
0 EX15 1HN EX17 4JG 28
1 EX15 1HN Exeter Airport 28
2 EX15 1HN Cornish Arms Tavistock 62

Comparing these with real-world travel times, it looks like they’d be reasonably accurate for early morning free-flowing traffic, though optimistic in some cases and pessimistic in others.

travel_time_matrix_car_valhalla = build_time_matrix_valhalla(
    origins_gdf=origins,
    destinations_gdf=destinations,
    valhalla_config_path="../../datasets/devon-260422_valhalla.json",
    costing="auto"
)

Let’s take a look at a detailed breakdown of this journey.

Warning

This point-to-point router isn’t really r5py’s strong point! So these routes may look a bit squiffy - but they do show us something useful for our experiments, so I’ve left it in.

This is explained in the following github issues: https://github.com/conveyal/r5/issues/863, https://github.com/r5py/r5py/issues/386

We haven’t used the point-to-point routing server for many years and it is not actively maintained. This dates from a time when we were exploring use of R5 as a replacement for OpenTripPlanner, but there has since been a clearer division of roles between the two projects with OpenTripPlanner 2 handling passenger-facing and point-to-point routing, while R5 is specialized in many-to-many urban analytics use cases. The point-to-point routing code paths do work somewhat differently than the one-to-many routing we use heavily for travel time mapping and accessibility calculations. We have not (yet) removed the point-to-point functionality in case anyone finds it useful, but realistically we probably won’t spend time exploring issues with this part of the codebase.

detailed_itineraries = r5py.DetailedItineraries(
    transport_network,
    origins=origins,
    destinations=destinations,
    transport_modes=[r5py.TransportMode.CAR],
    snap_to_network=True,
)

    ax, # the figure we created using our plot method
    crs=detailed_itineraries.crs.to_string(), # we can pull the CRS out of the geodataframe!
    )

Repeating this with the modified matrix

Now let’s repeat this with our new matrix.

transport_network_modified = r5py.TransportNetwork(
    "../../datasets/devon-260422-modified.osm.pbf",
)

Our travel times appear to be unchanged.

travel_time_matrix_car_modified = r5py.TravelTimeMatrix(
    transport_network_modified,
    origins=origins,
    destinations=destinations,
    transport_modes=[r5py.TransportMode.CAR]
    )

travel_time_matrix_car_modified
from_id to_id travel_time
0 EX15 1HN EX17 4JG 28
1 EX15 1HN Exeter Airport 28
2 EX15 1HN Cornish Arms Tavistock 62

What about the detailed routes - even if they’re probably not right?

detailed_itineraries_modified = r5py.DetailedItineraries(
    transport_network_modified,
    origins=origins,
    destinations=destinations,
    transport_modes=[r5py.TransportMode.CAR],
    snap_to_network=True,

)

These have changed!

detailed_itineraries_modified
from_id to_id option segment transport_mode departure_time distance travel_time wait_time feed agency_id route_id start_stop_id end_stop_id geometry

cx.add_basemap(
    ax, # the figure we created using our plot method
    crs=detailed_itineraries_modified.crs.to_string(), # we can pull the CRS out of the geodataframe!
    )

Repeating with our traffic-altered file

Finally, let’s repeat with our traffic-altered file.

transport_network_modified_traffic = r5py.TransportNetwork(
    "../../datasets/devon-260422-modified-traffic.osm.pbf",
)

Once again, our travel matrix times are unchanged.

travel_time_matrix_car_modified_traffic = r5py.TravelTimeMatrix(
    transport_network_modified_traffic,
    origins=origins,
    destinations=destinations,
    transport_modes=[r5py.TransportMode.CAR]
    )

travel_time_matrix_car_modified
from_id to_id travel_time
0 EX15 1HN EX17 4JG 28
1 EX15 1HN Exeter Airport 28
2 EX15 1HN Cornish Arms Tavistock 62

But our detailed itineraries have changed.

detailed_itineraries_modified_traffic = r5py.DetailedItineraries(
    transport_network_modified_traffic,
    origins=origins,
    destinations=destinations,
    transport_modes=[r5py.TransportMode.CAR],
    snap_to_network=True,

)
detailed_itineraries_modified_traffic
from_id to_id option segment transport_mode departure_time distance travel_time wait_time feed agency_id route_id start_stop_id end_stop_id geometry
0 EX15 1HN EX17 4JG 0 0 TransportMode.CAR NaT 21388.334 0 days 00:26:54 0 days None None None None None LINESTRING (-3.39673 50.85504, -3.39672 50.855...

ax = detailed_itineraries_modified_traffic.plot(column="to_id")

cx.add_basemap(
    ax, # the figure we created using our plot method
    crs=detailed_itineraries_modified_traffic.crs.to_string(), # we can pull the CRS out of the geodataframe!
    )

NoteWhat’s going on?

It looks like routingpy uses some other way of calculating travel time when using its matrix function.

And they’re not bad! But it does mean we won’t be able to use this method for things like traffic modifications either.

Valhalla

Let’s compare with valhalla, a routing engine that’s much more focussed on car travel times.

In the past, valhalla had to be set up in a fairly daunting way, but we now have the pyvalhalla option, which is much more approachable!

prepare_valhalla_network(
    osm_path="../../datasets/devon-260422.osm.pbf",
    output_dir="../../datasets/",
    output_name="devon-260422_valhalla.json"
)
Using existing Valhalla build
{'config_path': 'C:\\lokigi\\examples\\datasets\\devon-260422_valhalla.json.json',
 'tile_dir': 'C:\\lokigi\\examples\\datasets\\devon-260422_valhalla.json_tiles',
 'traffic_path': 'C:\\lokigi\\examples\\datasets\\devon-260422_valhalla.json_traffic.tar'}
travel_time_matrix_car_valhalla = build_time_matrix_valhalla(
    origins_gdf=origins,
    destinations_gdf=destinations,
    valhalla_config_path="../../datasets/devon-260422_valhalla.json",
    costing="auto"
)
travel_time_matrix_car_valhalla
from_id to_id travel_time_minutes distance_km
0 EX15 1HN EX17 4JG 21.783333 26.503
1 EX15 1HN Exeter Airport 14.166667 17.259
2 EX15 1HN Cornish Arms Tavistock 54.383333 89.2

This has worked!

Although compared to google maps, it seems quite optimistic - more so than r5py was.

We can now repeat this with our modified files.

prepare_valhalla_network(
    osm_path="../../datasets/devon-260422-modified.osm.pbf",
    output_dir="../../datasets/",
    output_name="devon-260422_valhalla-modified"
)
Using existing Valhalla build
{'config_path': 'C:\\lokigi\\examples\\datasets\\devon-260422_valhalla-modified.json',
 'tile_dir': 'C:\\lokigi\\examples\\datasets\\devon-260422_valhalla-modified_tiles',
 'traffic_path': 'C:\\lokigi\\examples\\datasets\\devon-260422_valhalla-modified_traffic.tar'}
travel_time_matrix_car_valhalla_modified = build_time_matrix_valhalla(
    origins_gdf=origins,
    destinations_gdf=destinations,
    valhalla_config_path="../../datasets/devon-260422_valhalla-modified.json",
    costing="auto"
)

This looks a little better - but it’s still optimistic, and the journey to the Cornish Arms has actually become a tiny bit faster, which is unexpected!

travel_time_matrix_car_valhalla_modified
from_id to_id travel_time_minutes distance_km
0 EX15 1HN EX17 4JG 24.066667 20.382
1 EX15 1HN Exeter Airport 16.1 23.31
2 EX15 1HN Cornish Arms Tavistock 54.35 89.2

And finally, let’s do this with our very heavy traffic file that assumed all traffic would only be travelling at 60% of the listed road speed.

prepare_valhalla_network(
    osm_path="../../datasets/devon-260422-modified-traffic.osm.pbf",
    output_dir="../../datasets/",
    output_name="devon-260422_valhalla-modified-traffic"
)
Using existing Valhalla build
{'config_path': 'C:\\lokigi\\examples\\datasets\\devon-260422_valhalla-modified-traffic.json',
 'tile_dir': 'C:\\lokigi\\examples\\datasets\\devon-260422_valhalla-modified-traffic_tiles',
 'traffic_path': 'C:\\lokigi\\examples\\datasets\\devon-260422_valhalla-modified-traffic_traffic.tar'}
travel_time_matrix_car_valhalla_modified = build_time_matrix_valhalla(
    origins_gdf=origins,
    destinations_gdf=destinations,
    valhalla_config_path="../../datasets/devon-260422_valhalla-modified-traffic.json",
    costing="auto"
)
travel_time_matrix_car_valhalla_modified
from_id to_id travel_time_minutes distance_km
0 EX15 1HN EX17 4JG 35.05 18.699
1 EX15 1HN Exeter Airport 25.466667 23.309
2 EX15 1HN Cornish Arms Tavistock 88.566667 88.944

So we can conclude that valhalla definitely responds to the maximum speed tags in a way that routingpy doesn’t - though it’s still not a perfect fix.

Tip

Routingpy remains an extremely good option if you are interested in public transport.

Valhalla is probably the better choice if you are looking for car travel times.

Valhalla does also have the benefit of having no java requirements whatsoever - so it’s easier to install in locked down environments.

For some projects, you may end up using a mix of both!

Let’s do one more modified file to see if we can make a difference.

This time, we’ll apply our same substantial slowdown to unclassified roads.

On top of that, we’ll add the assumption that all journies are slower than the posted speed limit on average, so we’ll bring speeds down to 90% of reality.

Advanced valhalla route inspection and debugging

We can do a bit more debugging…

from valhalla import Actor

result, summary = valhalla_detailed_route(engine=Actor("../../datasets/devon-260422_valhalla-combined-modified.json"),
                        origin=(origins.iloc[0].latitude, origins.iloc[0].longitude),
