![]() And even if this slightly neurotic “Cruise Control Game” really didn’t save much time or gas, it kept me mentally-alert on a drive with very few attractions. Striving to stay in the right lane of this two-lane freeway left a passing lane open for those that wanted to zoom by and risk getting a ticket. Making small adjustments to speed, instead of larger brake-taps and gas-mashes, put our gas mileage at about 25.7 mpg, compared to around 24. So I try to keep that in mind - and keep my lead shoe very close to the slow and fast pedals. I am afraid that leaving my foot off of the pedals decreases my reaction time, if I need to react to a sudden slow down. My biggest insecurity with cruise control is the lack of use of my right foot. The difference between human and computer efficiencies may sometimes be infinitesimal, but the challenge was not. Hitting the brakes turns off cruise control and also hurts gas mileage more than just lifting on the gas. I would try hard to not mash the brake pedal. When we approached slower cars, I would dial down the cruise control speed with my left thumb ahead of time. These kept me engaged in the silence of the car’s cabin. There were three goals on this straight-shot ride to Savannah: increase gas mileage, stay in the right lane as much as possible, and hit the brakes as little as possible. I choose nine miles per hour over the limit, because 10 and above is usually what stands out to law enforcement. The speed limit is 70 miles per hour on I-16, so I set the cruise control for 79. I hit the reset button on the steering wheel, erasing the bad gas mileage-average that city-driving created. So on Thanksgiving Day, while the Macy’s Parade crept along in New York City, I concocted a new car game as we cruised I-16 leaving Macon. I enjoyed that challenge on that trip and a few other road trips since. My new relationship with cruise control bore a “game” where I watched the “miles per gallon” gauge increase instead of my previous game of filing down the “ETA” on my Google Maps navigation. See this picture for example.Last spring, I wrote about a road trip where I landed a speeding ticket in our new car. actually, only a few cars can move at a time - just like in the block sliding problem. So, is there at least some approximate algorithm to do this?īy traffic jam I do not mean a situation where the traffic is going on very slowly, but otherwise is still going on, but a situation where cars are actually blocked by other cars, and cannot move forward, or backwords. So far, the 'sliding blocks' game/puzzle seems to me to be a simpler version of the traffic jam problem (some variants of the game are even called Rush Hour), but it seems that this kind of problem is PSPACE-complete (which is even harder than NP-complete), according to I have googled 'traffic jam solve algorithm', but I've found results about preventing jams (not solving jams once they occurred), or results about mathematical modelling of the traffic jams (or mining other kind of data from a traffic jam) - which is not what I'm looking for. Is there an algorithm for solving a gridlock (traffic jam)? Given a gridlock situation, this algorithm should tell which moves each car should make, and in which order the cars should move, so that the congestion is eliminated and the cars can go in the direction they intended to.
