A stretch of the main road between here and Swindon has suffered from the veerge being chewed up by trucks falling off the edge of the adequately wide road. So for the last few days, they've been filling the resultant trench with hardcore, and today , moving the verge back on top of it.

Theory says, that as traffic increases, you need longer waits, and longer greens, as each changeover adds a period with no-one moving, increasing the queues. These people don't seem to know this, and react, like many, with more changeovers as traffic increases. 15 minutes to travel 1 mile. Exacerbated by 30 cars through one way, 6 the other. This then leads to many jumping the red, which delays the other end, who then jump the lights, until one end gets a double green, as it hadn't celared before the changeover again. Meanwhile, lad sits in his truck, headlamps on, dazzling the passing traffic, staring into his phone, oblivious to the traffic.
