-
Have all recommendations from the previous stage been followed? If not, why not?
-
Is the desired speed compatible with the cross-section and other design elements and is the desired speed realistic?
-
Cross-section:
a. Has delineation of the carriageway with a kerb been proposed?
b. Is there adequate space for all groups of road users?
c. Is there appropriate separation between various groups of road users?
- Horizontal and Vertical alignment and visibility:
a. Does the proposed alignment satisfy any demands on visibility at junctions and sight distances on free sections?
b. Will sight distances/visibility be blocked by traffic signs, guardrails, bridge parapets, buildings, rigid obstacles or plantations (now and in the future)
c Can parts of the project constitute a risk, especially in combination (e.g. peaks in the vertical alignment plus sharp horizontal bends, crests of hills plus traffic signals)?
-
Are the lane widths, shoulders, medians and other cross-section features in accordance with standard design and adequate for the function of the road?
-
Check whether there are undesirable variations in cross-section design. Check cross-falls, which could affect safety, particularly where sections of existing highway have been utilized, or where there have been compromises to accommodate access to abutting properties.
-
Check the safety aspects of shoulder provision, including the provision of paved and earthen shoulders, the width and treatment on embankments and cross-fall of shoulders? Are the shoulders likely to be used by slow-moving vehicles or cyclists?
-
Check for the provision of climbing lanes in hilly sections where vertical gradients are steep for considerable length of the highway?
-
Junctions, interchanges and their design:
a. Will road users coming from all directions (including side roads) be able to see that they are approaching a conflict area? Are give-way lines, stop lines, turning lanes and ramps clearly visible?
b. Are existing conjoining and intersecting roads appropriately adjusted and matched to the new road (without sharp bends and gradients)?
c. Do the routes of road users through the junction seem clear for all directions and manoeuvres?
d. Is there sufficient space for all types of vehicles to undertake all manoeuvres?
e. Are the crossing facilities for pedestrians and non-motorised traffic adequate and safe?
f. Can parking cause problems?
g. Have roundabouts been considered?
(In urban areas, ghost markings and left-turning lanes with islands are safest; they prevent overtaking and assist pedestrians and cyclists who are crossing the road.)
-
Decide whether or not old, unremoved section of road can give undesired optical directions.
-
Special points at roundabouts:
a. Are all entrance lanes curved and is speed adequately reduced?
b. Will the central island be visible?
c. Are the measures taken for the benefit of pedestrians from a safe stopping distance and cycle traffic adequate?
- At the junction/transition to existing roads (especially from multi-lane to two-lane, dual to single carriageway):
a. Are there sudden changes of alignment?
b. Does the road standard change too rapidly, or can road users clearly see and recognize the transition in good time?
c Would a roundabout be able to mitigate any sudden changes in standards and alignment?
-
Are existing junctions and intersections adjusted and matched to the new road appropriately (without sharp bends and gradients)?
-
Are there any constructions that will be difficult to drain and are the cross-fall and any gutter gradient adequate at the critical spots?
-
Are there places where there is a risk of flooding?
-
Will overtaking be prevented at critical places (not simply by restrictions, but also by making it quite apparent that overtaking is prohibited)?
-
If signs and road markings have been proposed:
a. Are the markings consistent and are they adequate?
b. Has the quantity of information been kept at a reasonable level?
-
If markings have not been proposed: will special markings be necessary?
-
Is there any risk that cannot be "marked out of existence"?
-
Will there be any large sign constructions? If so; will guardrails or breakaway safety devices protect them?
-
Has it been proposed that lighting be located on the outside or inside of bends?
-
Will it be possible to carry out maintenance work (on lighting, gantries, plantations, etc.) safely and without using the carriageway or cycle path?
-
Is the landscaping design or plantation likely to lead to a lowering of safety with mature or seasonal growth? Is frangible vegetation appropriate?
-
Are there arrangements for safe access by emergency vehicles? Check the design of medians and barriers, and the ability of emergency vehicles to stop without necessarily disrupting traffic?
-
Pedestrians
a. Have pedestrian needs been considered?
b. If footpaths are not specifically provided, is the road layout safe for use by pedestrians, particularly at blind corners and on bridges?
c. Are pedestrian subways or footbridges sited to provide maximum use?
d. Is the avoidance of footbridges or subways possible by crossing the road at grade?
e. Has specific provision been made for pedestrian crossings, school crossings or pedestrian signals?
f. Are pedestrian refuges/kerb extensions needed?
g. Whether needs of disabled road users taken care of?
-
Have the needs of public transport users been considered? Are bus stops positioned for safety?
-
Is lighting envisaged in specified locations of the project? Are the difficulties of illuminating sections of the road caused by trees or over bridges, for example? Are there any aspects of the provision of the lighting poles, which would require consideration from the safety point of view in their being struck by vehicles?
-
Is adequate safe access to the work site available?
-
Are there any factors requiring specific road safety provision, including maintenance?
-
Are there any traffic management features, which would require special attention during construction or during the transition from construction to full operation?
-
Other checks made at discretion of auditor or client.
