Guidance: 04 If the pavement on an approach in which these detectors are to be installed is cracked,the project should include resurfacing of the areas where the detectors and lead-in cables are to be placed. Support: 05 Typical installation details for inductive loop and magnetic detectors are shown on the Standard Plans.The longitudinal location(setback)of detectors relative to the limit line depends on the speed of traffic and the type of detector operation desired. See Table 4D-101(CA)for suggested setback from Limit lines. Section 4D.104(CA) Bicycle Signals Support: of A bicycle signal(see Figure 4D-112(CA))is an electrically powered traffic control device that may only be used in combination with an existing traffic signal. Bicycle signals shall direct bicyclists to take specific actions and may be used to improve an identified safety or operational problem involving bicycles. Refer to CVC 21450. Standard: 02 Only green,yellow and red lighted bicycle symbols,shall be used to implement bicycle movement at a signalized intersection.The application of bicycle signals shall be implemented only at locations that meet Caltrans Bicycle Signal Warrants(see Section 4C.102(CA)). 03 A separate signal phase for bicycle movement shall be used. Guidance: 04 Alternative means of handling conflicts between bicycles and motor vehicles should be considered first. 05 Two alternatives that should be considered are: A. Striping to direct a bicyclist to a lane adjacent to a traffic lane such as a bike lane to left of a right-turn-only lane. B. Redesigning the intersection to direct a bicyclist from an off-street path to a bicycle lane at a point removed from the signalized intersection. - 06 A bicycle signal phase should be considered only after these and other less restrictive remedies have had an adequate trial with enforcement and with the result that the collision frequency has not been reduced Section 4D.105(CA) Bicycle/Motorcycle Detection Standard: 01 All new limit line detector installations and modifications to the existing limit line detection on a public or private road or driveway intersecting a public road(see Section 1A.13 for definitions)shall either provide a Limit Line Detection Zone in which the Reference Bicycle-Rider is detected or be placed on permanent recall or fixed time operation.Refer to CVC 21450.5. 02 All new and modified bike path approaches to a signalized intersection shall be equipped with either a Limit Line Detection Zone or a bicyclist pushbutton,or else the phase serving the bike path shall be placed on permanent recall or fixed time operation.A bicyclist pushbutton,if used,shall be located on the right side of the bike path and where it can be reached from the bike path.See Section 9B.11 for bicycle regulatory signs. 03 At new signalized intersections or when the advance detection is being replaced at existing signalized intersections,phases with advance detection only shall be placed on permanent recall. Support: 04 The requirement to detect the Reference Bicycle-Rider in the Limit Line Detection Zone is technology-neutral. Option: os The detection zone in a bike lane may be narrower than 6 feet.See Figure 4D-111(CA). os A Bicycle Detector Symbol may be used.See Sections 9B.13 and 9C.05. 07 A bicyclist pushbutton may be used to supplement the required limit line detection. Support: oa See Section 9B.10 for bicycle regulatory signs.
