Feature: Car - Max speed restrictions
OSRM will use 4/5 of the projected free-flow speed.
Background: Use specific speeds
Given the profile "car"
Given a grid size of 1000 meters
Scenario: Car - Advisory speed overwrites maxspeed
Given the node map
| a | b | c |
And the ways
| nodes | highway | maxspeed | maxspeed:advisory |
| ab | residential | 90 | 45 |
| bc | residential | | 45 |
When I route I should get
| from | to | route | speed |
| a | b | ab | 47 km/h +- 1 |
| b | c | bc | 47 km/h +- 1 |
Scenario: Car - Advisory speed overwrites forward maxspeed
Given the node map
| a | b | c |
And the ways
| nodes | highway | maxspeed:forward | maxspeed:advisory:forward |
| ab | residential | 90 | 45 |
| bc | residential | | 45 |
When I route I should get
| from | to | route | speed |
| a | b | ab | 47 km/h +- 1 |
| b | c | bc | 47 km/h +- 1 |
Scenario: Car - Advisory speed overwrites backwards maxspeed
Given the node map
| a | b | c |
And the ways
| nodes | highway | maxspeed:backward | maxspeed:advisory:backward |
| ab | residential | 90 | 45 |
| bc | residential | | 45 |
When I route I should get
| from | to | route | speed |
| b | a | ab | 47 km/h +- 1 |
| c | b | bc | 47 km/h +- 1 |
Scenario: Car - Directional advisory speeds play nice with eachother
Given the node map
| a | b | c |
And the ways
| nodes | highway | maxspeed:advisory | maxspeed:advisory:forward | maxspeed:advisory:backward |
| ab | residential | 90 | 45 | 60 |
| bc | residential | 90 | 60 | 45 |
When I route I should get
| from | to | route | speed |
| a | b | ab | 47 km/h +- 1 |
| b | a | ab | 59 km/h +- 1 |
| b | c | bc | 59 km/h +- 1 |
| c | b | bc | 47 km/h +- 1 |
