Using images or content with text Use a single clear image or graphic that illustrates your point Keep your points short and succinct Use bold for emphasis Dept. Name
DMURS Practical Implications Traffic Congestion (3.4.2) No new roads for cost and environmental reasons Maximise efficient use of road space (Fig 3.25) Max link capacity at optimal speed (Fig 3.26) Accept some level of congestion Planning and Strategic Infrastructure Department
DMURS Practical Implications Signing and Lining (4.2.4) Traffic Signs Manual Advises against over-provision of signs (1.1.10) shall or must, should and may (1.1.12) Minimise signage, esp. on local streets Naked streets in UK (Fig4.16) Lining less obtrusive than signs Better to have self-regulating design Planning and Strategic Infrastructure Department
DMURS Practical Implications Street Furniture (4.2.5) Place with care within cross-section Retain historic items Minimise pedestrian guardrails Segregation encourages speed Implies design problem Use street furniture (Fig 4.19) Planning and Strategic Infrastructure Department
DMURS Practical Implications Materials and Finishes (4.2.6) Define space, calm traffic, and improve legibility Reduce the need for barriers, signing and lining Can be expensive Hierarchy (Fig 4.26) Planning and Strategic Infrastructure Department
DMURS Practical Implications Pedestrians and cyclists (4.3) Footway widths 1.8m 4.0m (Fig 4.34) Pedestrian crossings (4.3.2) Zebras for moderate flows (Fig 4.37) Informal (raised?) courtesy (Fig 4.38) Avoid staggered crossings Minimise crossing distances Provide refuges (with PBUs at signals) Planning and Strategic Infrastructure Department
DMURS Practical Implications Junction Design (4.4.3) Balanced approach not just car capacity Ped crossings on all arms Reduce kerb radii Omit left turn slips (Fig 2.8) Include ped, bike, bus delays in optimisation Minimise cycle times Avoid large roundabouts Difficult for peds and bikes Consider compact roundabouts Planning and Strategic Infrastructure Department
DMURS Practical Implications Visibility distances (4.4.4) Much lower than DMRB (Table 4.2) Alignment (4.4.6) Arterial and Link Streets: retain directness Local Streets: speed reducing curves (Fig 4.65) Planning and Strategic Infrastructure Department
DMURS Practical Implications On-street parking and loading (4.4.9) Function Commercial viability of centres Calm traffic Reduce parking on footpaths Design Maximum 15m continuous length Distinct from carriageway Perpendicular on one-side only Verge / buffer adjacent to cycle lanes Planning and Strategic Infrastructure Department
DMURS Practical Implications What Streets will look like Permeable neighbourhoods No more distributor roads with high walls Narrower carriageways, wider footpaths Tighter radii Shorter cycle times at traffic signals No left turn slip roads at signals No large roundabouts No pedestrian barriers More on-street parking
