• Crosswalk – portion of a roadway ordinarily included within the prolongation or connection of the lateral lines of sidewalks at intersections, or any portion of a roadway distinctly indicated for pedestrian crossing by lines or other markings on the surface.

• Intersection – area embraced within the prolongation or connection of the lateral curb lines, or, if none, then the lateral boundary lines of the roadways of two highways which join one another at, or approximately at, right angles, or the area within which vehicles traveling upon different highways joining at any other angle may come in conflict.

• Official traffic-control signal – any device, whether manually, electrically or mechanically operated, by which traffic is alternately directed to stop and to proceed.

DEFINITIONS



DEFINITIONS• Right-of-Way – privilege of the immediate use of the

highway.

• School District – territory contiguous to and including a highway for a distance of two hundred feet in either direction from a schoolhouse in a city.

• Traffic – pedestrians, ridden or herded animals, vehicles, streetcars, and other conveyances either singly or together while using any highway for purposes of travel.

• Vehicle – every device in, upon, or by which any person or property is or may be transported or drawn upon a highway.



DEFINITIONS

VEHICLE/PEDESTRIAN TRAFFIC LAWS

• Important Vehicle Laws to Know:– Vehicles entering stop or yield intersections

must stop at clearly marked stop line or before entering the crosswalk [I.C. 321.322]

– Yeild to Pedestrians within intersections or crosswalks [I.C. 321.327]

– Driver's of vehicles shall exercise due care to avoid colliding with pedestrians upon a roadway including observing children [I.C.321.329].

– No Stopping, standing, or parking on a crosswalk, sidewalk or in front of a ramp or curb cut [I.C. 321.358]

http://search.legis.state.ia.us/NXT/gateway.dll?f=templates&fn=default.htm







When required to stop, vehicular traffic must stop before entering the crosswalk or behind a clearly marked stop line [I.C. 321.322]

6





When traffic control signals are not in place, the driver of a vehicle shall yield the right-of-way to pedestrians in crosswalks or any unmarked crosswalk at an intersecion [I.C. 321.327]

7





Every driver of a vehicle shall exercise due care to avoid colliding with any pedestrian upon any roadway and shall exercise due care upon observing any child upon the roadway. [I.C.321.329]





No parking on a sidewalk, in a crosswalk, in front of a curb cut or ramp or within 10’ of a flashing beacon, stop sign, or traffic-control signal on the side of the road [I.C. 321.358]

• Pedestrian laws to know:– Pedestrians are subject to signals [I.C. 321.325]– Pedestrians shall walk on left side of road [

I.C. 321.326]– Pedestrians have the right-of-way where traffic

control signals are not in place or in operation [I.C. 321.327]

– Pedestrians crossing other than at crosswalk shall yield right-of-way to all vehicles upon roadway [I.C. 321.328]

VEHICLE/BICYCLE TRAFFIC LAWS

• Bicycle Law– Every person

propelling a device by human power has all of the rights and all of the duties applicable to the driver of a vehicle [I.C. 321.1 & 321.234]





TRAFFIC SIGNS, SIGNALS, AND MARKINGS

• Traffic Control Devices Include:

– Traffic signs

– Traffic signals

– Pedestrian signals

– Pavement markings

• Must satisfy five basic requirements:

– Fulfill a need;

– Command attention;

– Convey a clear, simple meaning;

– Command respect from road users;

– Give adequate time for response.



19

TRAFFIC SIGNS, SIGNALS, and MARKINGS

• Early Traffic Control Devices:– 1911, a centerline is painted on a

Michigan road

– 1914, the first electric traffic signal is installed in Cleveland

– 1915, the first STOP sign appears in Detroit

– 1916, the Federal-Aid Act requires that a State have a highway department before it can get Federal money

– 1918, Wisconsin is the first state to erect official route signs as part of its maintenance functions

– 1920, the first 3-color traffic signal is installed in Detroit



20

TRAFFIC SIGNS, SIGNALS, and MARKINGS

• Background Law:

– I.C. 761-130.1(321) Constitutes the Manual on Uniform Traffic Control Devices (MUTCD), 2003 ed. As the manual and specifications a uniform system of traffic control devices in Iowa.

– 130.1(1) Gives exceptions to manual for specific for school zones regarding portable or part-time stop signs:

• Emergency and temporary traffic control purpose

• At appropriate school crosswalks.



Uniformity

• Reasonably safe and effective traffic control through uniformity:

– Policies– Practices– Standards



Definitions• School Area – Those streets and highways abutting the grounds of

an active educational institution that includes school property. Only streets and highways that are adjacent to a school are included in the school area.

• School Zone – That portion of a street or highway located within a school area that is subject to a reduced speed limit at certain times of a day. A school zone is defined by traffic control devices and normally adjacent to school property. It may be established at other locations when justified by an engineering study. School zones are not to be applied in a blanket manner for all streets and highways within a school area.

• School Crossing – An official school student crossing on an adopted school route plan of a school safety program. Any crossing not so officially designated is termed a “pedestrian crossing.”



MUTCD

23

SCHOOL AREA TRAFFIC SIGNS

• Standard

– shall be retroreflectorized or illuminated.

– shall have a yellow or yellow-green background with a black legend and border.

– should be placed where messages are most effective without restricting lateral clearance or sight distances.

– Placement should consider highway design, alignment, vehicle speed, and roadside development.

• The School Speed Limit assembly shall be

– fixed-message sign assembly

– changeable message sign.

• A Speed Limit Sign Beacon also may be used, with a WHEN FLASHING legend, to identify the periods that the school speed limit is in effect.
