Ada Case Study

The city of Seward, Alaska, has been addressing ADA accessibility issues around town. The city has recently completed work that will make it easier for people with disabilities to get around town. Sidewalks have been replaced or repaired, curb cuts have been fixed, and some damaged ramps and old railings have been repaired. The city has also increased the number of handicap parking spaces and installed yellow bump dots for the visually impaired. While these repairs now meet ADA compliance requirements, advocates for people living with disabilities say that the city still has a long way to go.

All municipalities are now required to adopt a comprehensive ADA transition plan, and they stand to lose their federal funding if they do not have a plan in place. The advocates are working with the city’s assistant manager in adopting a transition plan that would document and address each of its handicap accessibility issues over time, and regularly evaluate progress towards ADA compliance.

One of the priorities should be the Seward City Hall. A current problem with accessibility is where the handicap-accessible parking spaces are located. They need to be relocated next to the side entrance near the backdoor ramp, so people will not have to wheel or walk around to the back of the building from where the parking spaces are located. There are changes that also need to be made at the Seward Police Department and Seward Jail to make it easier for the disabled to utilize the facilities.

The city has made progress with recent improvements at the Seward Community Library Museum, and they are also working to provide greater handicapped parking areas at city paths, ball grounds, campgrounds, and parks. They recently installed compacted hard-pack D-1 gravel to provide at least the minimal required wheelchair access in these parking areas.

A lot more work will be needed to make more city facilities truly accessible to people with disabilities, but the improvements are already making a difference for the people of Seward. Disability advocates will continue to work with the city to help with the transition to ADA accessibility. It will take time and money, but the city of Seward is working toward a future where everyone will have access to all city facilities.

The paper describes the design and implementation of a distributed Ada system. Ada is not well defined with respect to distribution, and any implementation for distributed execution must make a number of decisions about the language. The objectives in the implementation described here are to remain as close to the current definition of Ada as possible, and to learn through experience what changes are necessary in future versions of the language. The approach taken to distributing a single program is to assign library units that compose it to nodes of the distributed system. In a formal sense the semantics of a program is independent of the distribution because the semantics is interpreted to include all possible behaviours that result from different distributions. However, the functionality of the distributed program may then depend on the distribution in the sense that program behaviour may be impacted by the time required for communication among the distributed modules, or parts of the program may continue to function in presence of failures. The implementation technique converts each distributed module into a standalone program that communicates with its correspondents; each of these may then be compiled by an existing Ada compiler. Issues discussed include the ramifications of sharing of data types, objects, subprograms, tasks, and task types. The implementation techniques used in the translator are described.
