I would like to get the road network length in OSM for the Africa and a dataset by Country. And for each country the length within the boundaries of the selected key urban areas like the capital, largest cities, or major port cities. In addition to length I would like to get data on road class (primary, secondary, tertiary), road surface type (paved, unpaved); road condition (good, fair, poor); and if possible an estimate of the traffic level in average number of vehicles per day (0-30, 30-100, 100-300, 300-1000, 1000-3000, more than 3000 veh/day). Assuming many countries have limited data in OSM, has some already done an estimate of network length using alternative sources?. Thanks, Alberto
