    Criss cross crash! What about a big ass 200stories tall ramp with an elevator and a loop to loop at the bottom?

      Yeah diamond interchanges kick ass. They made me nervous the first time I used one, since it was the kind where you end up driving on the opposite side of the road. But just follow signs and you’ll get where you need to go and there’s almost no risk compared to the garbage interchanges you usually see around interstates.

      I wouldnt bike on that painted bike lane across a right turn slip lane designed to make cars slow down as little as possible coming off the freeway

      There should be a protected bike lane in the median with a dedicated signal where the diamonds cross

        Those aren’t bike lanes. They are merging guides for the cars. So yeah it’s still lacking but better than a cloverleaf.

        Edit: sorry, there are bike lanes. I hadn’t noticed that there were two colors on my mobile

        Since there are traffic lights, I personally would no be worried about taking my bike through

    I’m not saying it’s good (those bike lanes look horrible), but they put in a diamond interchange in my city and it’s ironically the best car infrastructure we have.

    To be fair this looks slightly worse than ours, ours has more separation for pedestrians, but I feel much less stressed out that I only have to look one way when crossing, and no cars should be able to go when I am.

    They still do. they’ll run a green arrow light, probably because they’re used to “right turn on red”. I have been tapped by a car I was playing chicken with at that light.

    But other than the presence of morons, I’d pick the FREEWAY INTERCHANGE over a normal city light any day. That’s crazy to say but it just goes to show how even slightly better designed infrastructure makes a difference.

    Those bicycle lanes are ass though.

    North American has this concept in roadway design where traffic engineers feel the need to make every roadway large. Think of interstate interchanges.

    There is also this need to try and design roadways as both roads and streets, while maintaining the flow of high speed traffic at the same. This leaves us with neither good roads or enjoyable streets.

    Roads get you from point A to point B without regard for what’s in between or along the route. They are meant to move large amounts of traffic with minimal to no lights/stops/driveways.

    Streets on the other hand are “destinations” and are meant for the people that live along them. Streets are traffic calmed, streets give the right of way to pedestrians. Streets have driveways, and multiple interaction zones between people on foot, on bikes, and on cars.

    A street cannot act as a road nor can a road act as a street.

    This image trys to turn the underpass into a street (which it can be), but it’s main function is still designed as a high-speed roadway. So this leaves us with a combination of the two (a strode) which neight is a good road or a enjoyable street for the local community.

    Some examples of simplified highway off ramps that connect directly into traffic calmed streets.

    1000015677

    City planing also plays a role here, and its usually has to do how our we build city centres right next to highway off ramps. This leaves no room for proper roadway design where you “stepdown” your roadway classification.

    Good planing would have a interstate (130-100kph) connect to a highway (100-80kph), which then empties into a high-speed road (80-60kph), which steps down to a road 50-40kph, and then transitions into a street (30-10kph).

    Instead we have interstate highways empty right into a city street.

      I always wondered if instead of a two lane road every block you could have a city where it’s a four lane road every two blocks, with a single lane pedestrian/bicycle street alternating every other block there isn’t a road.

        Edit: who the heck wants to walk on the shoulder of a gigantic road like that too… wtf

          It is. There are traffic lights in front of the crossing for pedestrians and the bicycle lane is parallel to the car lane and logically both of the can only have a green light if the cars from the left have a red light and also the pedestrian have a green light for crossing.

        No, there are 2 spots where cars turning right cross a cycle lane going straight, without a traffic light.
        One of them is on the lakes coming from the left, the other on the lanes in the background coming towards the viewer.

          Theres a rule that no one follows on the roads, when turning right (or left for that matter) you come to a complete stop and then proceed. This applies even if there is no stop sign or the light is solid green.

          The only exception to this is if your signal light shows a green arrow pointing right, or left.

          The location in the image pointed out above tells motorists they can proceeded at full speed, run over the pedestrian at the crossing, run over the cyclists (that has the right of way), and drive head first into traffic in a effort to murge as quickly as possible.

          There should (at the minimum) be painted yeild the right of way marking on the road. Both before the pedestrians crossing at the off ramp and right before the bike lane crossing, which should be painted continuously.

          Kind of like this. 1000015681

          Though paint is no substitute for proper roadway design.
