I notice myself thinking quite differently behind the wheel of a motor car compared to how I think at the controls of a motorcycle or on a bicycle.</p> <p>Car driving makes me feel entitled and distant, like an absentee landlord. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=13290#post-162275 Fri, 15 Aug 2014 10:42:19 +0000 crowriver 162275@http://citycyclingedinburgh.info/bbpress/ <p>@sallyhinch, aye but you're not sitting in a ton of steel, glass and rubber travelling at 50mph, are you? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=13290#post-162246 Thu, 14 Aug 2014 22:12:15 +0000 sallyhinch 162246@http://citycyclingedinburgh.info/bbpress/ <p>To be fair, my mind is fairly often not on the job on my bike too... hopefully only on the quieter roads, but miles can go by without me noticing some days </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=13290#post-162242 Thu, 14 Aug 2014 22:00:52 +0000 HankChief 162242@http://citycyclingedinburgh.info/bbpress/ <p>It will be crowded in their minds as many have it concentrated on what their phone is telling them, what the radio is playing, what to have for tea etc. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=13290#post-162241 Thu, 14 Aug 2014 21:51:44 +0000 sallyhinch 162241@http://citycyclingedinburgh.info/bbpress/ <p>OR even the 'minds' of drivers! </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=13290#post-162236 Thu, 14 Aug 2014 20:08:40 +0000 dougal 162236@http://citycyclingedinburgh.info/bbpress/ <p>But who can <em>really</em> get in the minds of drivers? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=13290#post-162234 Thu, 14 Aug 2014 20:03:39 +0000 HankChief 162234@http://citycyclingedinburgh.info/bbpress/ <p><em><strong> Why are speeds higher with centre lines?</strong></p> <p>Getting into the ‘minds’ of drivers is not easy. A theory is that centre lines and hatching can provide a psychological sense of confidence to drivers that no vehicles will encroach on ‘their’ side of the road. There can also be a tendency for some drivers to position their vehicles close to a white line regardless of the traffic conditions, believing it is their ‘right’ to be in this position. Centre line removal introduces an element of uncertainty which is reflected in lower speeds.</p> <p>Although not identifiable in the data, it was noted on site that speeds of individual vehicles appeared to be particularly lower when they were passing other vehicles travelling in the opposite direction. This supports the theory that uncertainty and additional cautiousness is responsible for the speed reduction</em> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=13290#post-162229 Thu, 14 Aug 2014 19:28:19 +0000 chdot 162229@http://citycyclingedinburgh.info/bbpress/ <p>"</p> <p>Conclusion</p> <p>The data recorded in this study and subsequent analysis shows that there was a statistically significant reduction in vehicle speeds as a result of removing central markings on the carriageway.</p> <p>It is important to note that not all roads would be suitable for removing central markings, particularly where the markings highlight a particular hazard. If the technique is being considered, careful analysis of the site will be required to determine if it is appropriate.</p> <p>"</p> <p><a href="http://www.tfl.gov.uk/cdn/static/cms/documents/centre-line-removal-trial.pdf" rel="nofollow">http://www.tfl.gov.uk/cdn/static/cms/documents/centre-line-removal-trial.pdf</a> </p>
