1.Turn Restriction

Please verify every turn of a route to see if it is allowed by checking the traffic signs and arrows painted on the road.

1.1Traffic Sign/ Street Sign

The route makes a right turn into Elegance road. (14.896443,100.400628)

.

From the street imagery, we notice that right turn is not allowed.

 

Look for the traffic sign and the arrows painted on the road.

Only straight ahead is allowed.

 

.

.

1.2Double White Line

Continuous Double White Lines on the road indicates that the turn is not allowed.

..

Right turn is not allowed at the point where the double white lines started.

 

 

1.3Continuous Solid White Line & Broken White Line

Cars on the side of the solid white line are not allowed to cross the line to the other lane, while cars on the side of the broken white line are allowed to cross to the other lane.

 

In the example above, cars can cross from left to right lane but not vice versa.

.

.

 

Right turn is not allowed at the point where the double white lines started.

 

2.Cars Not Allowed
2.1Bus Only Lane

Some of the bus only lanes are not clearly seen on the map or street imagery.

The Des Voeux Road Central is a bus-only lane and cars are not allowed. There is

a sign indicating of this.

.

.

 

2.2Pedestrian Only

Some of the streets/ roads are only for pedestrian. Cars, buses, motorcycles are not allowed on this tyoe of roads.

.

.

.

The route starts at a path beside the ocean. Using Street Imagery we can see that the path is pedestrian only path.

The route here would be MNE – Cars Not allowed.

 

There are roads that restrict car access at all times. An example would be 渣甸坊in銅鑼灣

.

There are also part-time pedestrian only roads where cars are restricted to access in certain time of the day and/or certain day of the week.

An example is 北河街 between 鴨寮街 and 汝州街 in 深水

 

.

The example above is 赤柱大街 in which restricts car access from 7pm to 11pm on Friday and 11am to 11pm on Saturday and public holidays only .

3.Access Restricted

Refer to the GL 4.3.Access Restricted, If a route takes a shortcut through the parking area of a parking lot and does not end in an area associated with that parking lot, this is an Access Restricted MNE.

This route passes through a shopping mall parking lot and does not terminate in the parking lot, but get to a public road hence access restricted to be indicated.

.

.

..

4.Physical impossible

This route makes a left turn to the entrance of a shopping mall ( 22.421063,114.2258066).

From the street imagery, we notice that there are barriers at the junction and left turn if not allowed.

Note: Always check the route using street imagery to make sure no barriers.

.

.

 

The route keeps right to Edinburgh Place from Yiu Sing Street.

From the satellite view, we can see that there are painted barriers which indicate that the turn is not allowed.

Further confirm via street imagery, there are barriers at the junction and the turn if not allowed.

.

Check the route using street imagery to make sure no barriers.

Note:  Street imagery might sometimes be outdated and contains wrong

information. If the street imagery is too old (e.g taken several years ago), it would be a good idea to confirm with other reliable resources. You can also try to look at other street imagery near or around the area of interest to see if those are more up to date. The satellite imagery of the official government map of Hong Kong https://www.map.gov.hk/gm/ is a reliable source as it is frequently updated. The overhead satellite view is clear and detailed enough to see traffic features on the road.

For example this image was taken in 2011 and the park is still in place.

.

.

.

This image was taken in Dec 2016. It shows that the park is gone and a road runs through it.

An update satellite image from HK government map shows that the park is gone

(originally red line area).

6.Tips:
Please pay special attention to every turn, entrance and exit.
Always verify the route using satellite and street imagery of other map applications.
Some mapping applications and street imagery are convenient and somewhat reliable resources for confirming routes. However, we must pay attention to whether the information is update enough. Avoid using old street imageries and try to look for most updated ones.
Counter checking with other reliable official resources, e.g., https://www.map.gov.hk/gm/
http://hkerouting.gov.hk/drss/index.php?lang=E is advisable to check the route. Its basemap may not be up to date, but when querying for a route using start to end pin, (and adding points along the road that the route must take), the route typically looks up to date (i.e. the route may be up to date but the basemap may not, therefore it may look ‘off’ at times.)
