1) Bike Lanes:

  • Bike lanes are shared with vehicular traffic. Usually they are a cheaper option. Although the don’t offer any physical protection for the cyclist, most of the times using these lanes are stress free and safe. The ideal bike lanes are places with  1 + 1 lanes where there is no parking.

HW4-6

  • This picture shows three lanes with a bike lane in between two of them. The bikes are also allowed to turn right and therefore would have to travel in the car lane. both the car and bike use the same signal light at this intersection.

HW4-12

  • Although this bike lane feels safe and protected, it is still a bike lane. It has no physical protection for the bike. The only thing in between the bike lane and the travel lane is a 2 feet brick buffer, At the end of this lane in the picture there are no buffers. The bike lane is on the street next to the travel lane.

2)Bike Boulevards:

  • Bike Boulevards are roads with mix traffic. Mainly follow calm, local streets suited to serve through bicycle traffic while discouraging through motor traffic. Usually involves low speeds.

HW4-4

  • Cars are allowed in this street however there are alternative routes that discourage this street.  There are many speed humps along the road to ensure that the speeds of the vehicles is slow since it is shared with bikes. Also the brick road feels different than asphalt and makes the cars go slower than they would in normal asphalt.

3) Cycle Tracks:

  • Also know as protected bike lanes. Every form of traffic is separated. Bikes have a physical protection from cars. This protection could be parked cars, trees or any other buffer with a physical separation in between.

HW4-1

  • This picture shows a perfect example of a cycle track.  The narrow road ensures that cars slow down at crosswalks making it safe for pedestrians. Also the island crosswalk makes it easier for pedestrians since they only have to look one direction at a time when crossing. The bike lane is always protected by cars, trees or a large buffer with a curb.

HW4-5

  • This picture shows a two way bicycle track. It si mostly protected by a curb and a long row of trees. While ridding it, one does not worry at all about car traffic. It is also separated by trees and grass from the pedestrians.

4) Advisory Lanes:

Also known as suggestion lanes. These are meant for unlaned roads. The only suggested lanes are for bikes. However cars can use that space also. The central space is not a single lane; it is shared.


HW4-2

  • This two way road is right before a school zone so vehicles must be going at a slower speed. The slightly elevated speed hump makes cars slow down. There are also multiple speed hums along the road.

HW4-3

  • This advisory lane is inside the school zone. The narrow lanes make sure that cars go slow. There is also a pedestrian island so when crossing, a person only has to look one way at a time making it safer to cross. The island also works to slow cars down.

HW4-8

  • This is a very narrow two way advisory lane. Since the canal limits the length of the lanes, there is no space for a sidewalk. This road is not a problem since most cars avoid it and there is very low traffic.

5) Service Roads:

Also known as parallel roads Provides a low stress bicycle use along a main road. The road has low speed and little traffic.


HW4-10

  • This is a continuation of a service road. Cars are allowed on this road but since the road is blocked on the end there is little to no traffics. It is right in a school and since allot of children will be biking to school it was really important to make traffic as low as possible.

HW4-11

  • This service road is in front of a apartment complex where the only people driving in it are people that want to get to their apartment. The road is shared whit cyclist. Also speed humps and the brick road ensure that cars go slowly.

6) Bicycle Highway:

Bicylce Highways are stand alone bike paths. This is a safer and more pleasant environment. It is also faster.


Picture1

  • This picture shows a two lane bike highway. It is a significant distance from the highway and it is also elevated making it safe and comfortable to ride. It also has lights all along the lane so bikes can travel even if it is dark.
