Time and Schedule

CAMBUS time is established by Variations from your time piece or mobile device may occur. The drivers make every effort to safely operate on schedule, however, delays may occur due to unavoidable events or conditions including inclement weather, traffic, road construction, etc.

Bus Stops

All CAMBUS stops are marked by signs. For safety and reliability of service, riders may only board and exit at designated stops. Times posted at bus stops are departure times. Operators may every effort to safely operate on schedule. Unavoidable factors may impact this ability and your understanding is appreciated.

Due to large blind spots caused by trees, buildings, signs, and the bus itself, it is not always possible for operators to see riders approaching the stop from a nearby building or vehicle. To ensure boarding, riders are asked to be at the stop a couple minutes before the departure time. Riders can use the Transit mobile app to assist in determining when to be at the stop.

Boarding and Riding

Boarding - To help our services operate efficiently, riders are asked to board at the front doors and exit at the back doors. Be advised, all riders must stay behind the painted yellow line while the bus is in motion.

Riding - Please remember that eating, drinking, vaping, and smoking are not allowed on CAMBUS vehicles. Please be respectful of driver instructions. If possible, ask any questions you have for the driver when you board or at a bus stop; avoid asking questions when the bus is in motion so that the driver can focus on safely operating the vehicle.

Requesting a Stop

CAMBUS has two types of stops in the system.

Mandatory stops are stops where bus operators always stop to board and alight riders. Buses also sometimes have layovers at mandatory stops to prevent the bus from running ahead of schedule.

Optional stops are stops that are only served when a rider pulls the stop request cord and/or someone is waiting at the stop.

It is recommended that riders always pull the stop request cord about a block before the stop they need, even if it is a stop the bus always stops at. The stop request cord provides a visual and auditory cue to the driver to expect riders to disembark at the next stop.

Requesting Assistance

Operators are available to provide assistance to riders including:

  • Kneeling the bus to allow for easier boarding
  • Deploying a ramp for easier boarding, or to board a mobility device
  • Providing directions and system information
  • Answering questions about CAMBUS services
  • Requesting a priority seat for a rider

Drivers anticipate when additional assistance may be needed. Sometimes the need for additional assistance is not always apparent to the driver. If you need assistance, please make a request to the driver.

CAMBUS drivers make an effort to look for riders approaching the bus. However, limited visibility around bus stops exist due to buildings, trees, and campus signage, among others. The buses themselves also present large blind spots, particularly to the rear of the bus. For these reasons, CAMBUS may not always be able to wait for riders approaching from areas other than the bus stop. CAMBUS asks that riders are at the bus stop prior to the bus departure time to ensure boarding. Your cooperation with this also helps to ensure service delays are kept to a minimum.

To help determine when to leave a building or your vehicle to head to the bus stop, we recommend using the live bus map feature in Transit. Learn more about the Transit mobile app here.

CAMBUS provides information about detours and service in changes in several ways. Below is a list of options riders may use to learn about changes, and our recommendations for getting the most current information.

CAMBUS website

All service changes and most detours are posted to the CAMBUS website. Service changes and detours are typically posted about a week in advance, where possible. Emergency detours or service suspensions, such as for severe weather or an accident impacting our service area, may not be available on the website.

Transit mobile app

All service changes and all detours are communicated through the Transit mobile app, including emergency detours and service suspensions. Service changes and detours impacting a route will be visible on the individual route screen in the app. Riders may also “favorite” the routes they ride to receive push notifications (similar to a text message) to notify them of upcoming or current detours and service changes.

Viewing route information in the Transit app and subscribing to service alerts through the app is the best way to get the most current system information.

Facebook and Twitter

CAMBUS maintains a Facebook and Twitter channel (@uiowacambus). Most service alerts and detours are posted to these channels. Some emergency or sudden detours may not be posted to the social media channels. Riders are strongly encouraged to use the Transit mobile app to receive the most up-to-date information.

All CAMBUS vehicles that are out for service that day go through a “clean-up” process on weeknights. This means that most buses are cleaned each weeknight, unless they didn’t go out that day.

Cleaning practices include:

  • During the nightly “clean-up” process, buses interiors are cleaned with general cleaners before receiving a disinfectant spray over the entire interior of the bus. Bus exteriors are also washed.
  • At least once every 48 hours, the interior of each bus receives a UV light treatment that kills bacteria and viruses.
