There would be no at-grade intersections, driveways, traffic lights, crosswalks or at-grade railroad crossings. Montpelier's downtown is relatively compact and pedestrian-friendly, with sidewalks and crosswalks throughout the downtown area. Other investments should include installing crosswalks, road markings, benches, shelters and sidewalk art installations. Many crosswalks are also equipped with warning blocks. Warning blocks are also installed before some crosswalks in the Jalan Thamrin area. In some areas, blocks serving a directional function are installed within crosswalks. Unlike many other countries, however, blocks are not installed before crosswalks. A few laws may prohibit riding in crosswalks. A HAWK beacon is used only for marked crosswalks. Marked crosswalks are indicated at a minimum by a pair of white lines. In some cases stop or yield lines are used in advance of mid-block crosswalks. Colored crosswalks might have themes that reflect the immediate area. These crosswalks are planned to be installed by the end of 2017. In France, it is not mandatory that crosswalks exist. Tijuana uses landmark installations before crosswalks that are similar to those used in California.
